fcam & fcamera and HDRcapture Thread (Bugs, Ideas..etc)

[maxximuscool]

I've decided to make this thread to see how many people found any bugs with the fCamera app.

We can list it here and share our experienced with this cool new app.

Personally, I found something like this.

The screen flashing green when rotating.
I think this bug has been confirmed by the developer.

But if you have found any more please post it here.

===

I also would like to know how can i get HDR image with this app? I set it to HDR but the image captured is not muxed as one. All as separate files.

Also there is no Flash LED flash option at all. Camera sound is annoying lol. "Ding ding"!

Overall I like this app over the original camera, I can do so much more than the standard one. But there are still along way to go before it can replace the stock camera. :)

===

Keep the water pipe running !

[rm53]

for ready-made HDR, you need a different app from the FCam project, FCamera does not do this.

I found some minor problems: The month of the time stamp (used for naming the file) is incorrect (July is 06, should be 07).

As the raw files are really large (11MB) there should be an option to write only the JPEG formatted image in user-settable quality.

It should display appropriate warnings if the lens slider is closed before shooting, or not closed when terminating the app.

Behavior of the buttons on the right is a bit inconsistent, some update their shown A (automatic) value by itself, others only when pressing the camera button (like distance/focus).

Thank you FCam-team for that great app FCamera - can't wait for the other two apps to be pushed to Maemo Extras.

[mikemorrison]

There is no EXIF data in the output jpeg files. :(

[ericube]

Was a little bit excited when saw the news that we could shoot in RAW format on our N900. So did a wee bit test 2day, however, the results are so under expected.

I installed all the three apps, FCamera, Lowlight and HDRcapture. The FCamera shoots in DNG format, but when I preview the results in PS CS4 on my Mac, OMG, even much worse than the pictures taken by the default camera application. As I've got a really nice weather condition (good light condition) 2day in Glasgow, the results I tested is not accepted if Nokia calls this is 'something amazing'. All the pictures I took were in a very strange 'green' color, tried to modify them through Lightroom or CameraRaw on my Mac, it didn't help much to change the result.

I have to say, I love my N900, but the camera function is far behind my new iPhone4. iPhone4's camera result is amazing. So I used to think FCamera is the one that I can use to fight back, well, so far, it looks that I was wrong. Or maybe I missed sth about DNG format? Any pre-setup needs to be done before bringing them into PS or LR?

[sophocha]

I keep deleting photos under the Fcamera folder and once I open the application up they keep appearing again, so now I have a bunch of old files that are corrupted.Anyone has this problem?

[abadams]

We had a bad bug in our dng files we managed to introduce at the last minute that made everything cyan when viewed in photoshop. It's fixed and the update will be live soon. I think the green flash was fixed in our last update (this morning?). If not it will definitely be fixed in the next one - it's fixed in the version I have on my phone.

EXIF data in the jpegs is definitely on the todo list.

- Andrew (one of the fcam devs)

[abadams]

sophocha - fcamera stores a .dng file and a .dng.thumb file (which is a thumbnail, so that fcamera doesn't have to load the whole dng file just to browse through the images). I just discovered if you delete the .thumb file in the file manager without also deleting the .dng file, fcamera gets a little confused and shows an error message for that file. Could this be what's happening?

[maxximuscool]

When using the app, the battery draining really quickly. Is this a bug anyone else encounter?

[lsolano]

The screen flashing green when rotating.
I think this bug has been confirmed by the developer.


This is happening to my n900.

[maxximuscool]

Green Flashing when rotate has been fixed. Thanks to everyone help pointing it out earlier.

[d-iivil]

My device went into reboot loop after installing fcamera + driver. Got it back by flashing the rootfs.

Edit: seems like it was because fapman allowed me to install fcamera with Titan's kernel installed.

[pthomas22]

How do I view the dng files on a windows pc?
I have photoshop cs2 with the latest cameraraw plugin. It will open other dng files but not the ones produced by Fcam

[HoX]

If I use the default photo app, when I open fcamera I can only see a gray photo and I have to reboot the device to use it.

[toxaris]

Is that bug fixed yet?

[maxximuscool]

For now please avoid installing fCamera with Titan custom kernel.
fCamera is not compatible with Titan Kernel just yet. If you do install it then your device will be unstable or worst.

[junionwoon]

is the conflict between titan and fcamera kernels fixed yet??

longing to try out fcamera....

[sdstrowes]

I also would like to know how can i get HDR image with this app? I set it to HDR but the image captured is not muxed as one. All as separate files.
Try the hdrcapture app, which uses these libraries.

[sdstrowes]

Agree!

Saving RAW data is really cool, but I expect it's not a common use-case. I think that if the default behaviour were to save as JPEG (in a location the gallery will display it!), but with an option to also save as RAW, that the experience would be more immediately useful for users.

[peynaud]

How do you enable the flash when taking photos please? I've tried everthing... Flash works with the main software but not with Fcam.

:confused:

I have uploaded a fcam-drivers package for kernel-power

I always shoot Raw + JPEG on my Nikon DSLRs. The RAWs give me much greater latitude for post-processing tom-foolery, but it is handy to have the JPEGs for immediate posting to web galleries, social networking sites, etc. It would be great if there were an option to shoot in RAW and then do background/idle creation of the associated JPEGs. What would be even handier is to have an option to background create multiple JPEGs at different resolutions / quality levels for immediate posting.

There's already an option to save JPEG files as well - they get saved to the normal camera directory. Just drag down to get the config options, and its on the File Management tab.

[stickymick]

First the bugs.

As posted in the other thread by Berserk and myself - The date stamp on images taken with fCamera is 1 month behind.

I've found the application freezes momentarily during operation, which can lead to a bit of demented tapping of the screen, until you realise what's going on.

Now to the ideas/wish list.
Would it be possible to implement a widescreen mode like on the default cam?

And maybe some lens effects, if possible.

[janszoon]

Using the proximity sensor to make the controls appear would be awesome....that way you have a full screen display with you finger on the camera button. Then putting your thumb over the PS the would give you on screen controls. Please consider this all you smart coders.

[rotoflex]

A "dragging the shutter" mode would be nice, if incorporation of the flash is not a problem.

I am also enjoying fcam on my N900; thanks fcam developers.

[must4get]

FCamera is nice, Good work guys..
Please make sure you improve it and make a real good final app.

See some samples here. http://www.nokiatimes.com/2010/07/hdr-photos-and-manual-camera-settings.html

I noticed that every time I use the built in Camera app I had to restart the phone to use FCamera.

[gmuslera]

I noticed that every time I use the built in Camera app I had to restart the phone to use FCamera.

Its that happening to everyone? even reflashed my n900 thinking that that was happening because something i installed in the past or something related.

[maxximuscool]

This is quite weird, today I took the sunset photos to compare with my Camera but N900 picture turned out to be unbalanced in black and bad rendering. Never happened to me before. I think might be something to do with fcam-driver? Picture supposed to be amazingly breath taking but was ruined by the crappy contrast.

I think I'm going to try it again tomorrow after work and this time i'll use Automatic settings. :(

[BluesLee]

when i open the camera lens the default camera app does
not shoot up anymore. this must be related to fcamera, hdcapture
or lowlight app. maybe bless900 which i had to deinstall for the
above apps.

can someone help out?

Blues

[steph]

Hi guys, congrats on the beginnings of an app I know will go very, very far.

I did ask this in the Nokia announcement thread but it got drowned out, but would manual aperture control be possible? does the N900 even have a variable aperture or is exposure only controlled with sensitivity and shutter speed?

from looking at the exif from all my jpegs and a bit of googling it seems the aperture is fixed at f/2.8

[stickymick]

For some reason, since the last update, fCamera has been really thrashing my CPU.
Noticed this yesterday, after the update, when it was freezing momentarily during switching between screens and selecting options.

Decided to check "System Info Widget" today and the CPU was fluctuating between 70% & 100% while fCam was running in the background.

Anyone else seen this?

Hi! I had BlessN900 installed before. Removed without problems and since I'm using titan's kernel also installed titan's version of fcam driver.

I was playing with different options today and also took some pics with bundled camera app -- maybe I'm lucky, but I dont have any problems mentioned here - camera slider work OK (have set to start camera when slider opened, so I just quit default app and run fcamera), also, I tried to capture same motive with defult app and fcamera for comparison. As far I can tell, everything look as usual.

I didn't install lowlight, maybe is here the catch?

[deter3]

I got the same problem that freezing when switching between screens .I did not overstock . So I uninstalled the apps and wait for the fix .

[FarmerF]

a minor but confusing bug:
If you open the default camera app and switch to night modus and then close it and start fcam the display is completely gray (becomes green in hdr modus). To get the preview back you have to start the default app again and switch to auto mode.

Quality is generally quite well and with all the sliders you can make it that much better but the auto settings do not always give the ebst results (especially low light conditions).

--edit--

Another oddity I noticed, the raw images taken with fcam seem to be only 640x480 pixels, is that correct or did I miss a resolution setting somewhere? The corresponding saved jpg's are 2560X1944... If only I had known... Could have used the extra pixels http://talk.maemo.org/showpost.php?p=764908&postcount=506

[ewan]

Rather oddly the basic fcamera app is open source, but the Nokia built HDR and lowlight apps appear to be in non-free. That doesn't seem like a sensible decision for example apps.

[joshua]

hmmm nice great app

[FarmerF]

To expand a bit further on the above mentioned resolution problem:

The RAW images are around 10 mb which seems correct but in the gimp they take 2.9 mb memory which is odd. It almost seems as if the data is there but the file index is wrong (don't know the RAW format but I hope you can understand what I mean :))

Opening in UFRaw gives an error about not being able to use the camera white balance after which it hangs...

Also got some error about a TIFF directory something but can not reproduce it atm.

Lastly I'm still curious about other peoples resolution in the RAW images to know whether its just me or a general bug and will try with Photoshop later to see if that changes anything.

[yogi900]

Great apps..!!!

Any idea how to make panorama photos with this?

[FarmerF]

And the next part of this monologue :

The FCAM thing in a nutshell for non-developers seems to be the place to file bugs (go figure...) and the problems with dcraw are known and fixed (http://talk.maemo.org/showpost.php?p=763337&postcount=61) in SVN.

Will check with Photoshop as stated earlier and perhaps everything will be fine then.

[Switch_]

Will check with Photoshop as stated earlier and perhaps everything will be fine then.

Everything seems to work fine in Adobe CameraRAW 4.6 onwards, where Adobe included the *.dng extension that fcam works with. The only exception to this is that the picture metadata is incomplete and only contains (IIRC) ISO and...... Something else..... (!)

CameraRAW 4.6 is included in any Photoshop package from CS3 onwards, don't think CS2 had the RAW image capabilities. Also, the pixel dimensions are not 640 x 480 (307,200pix) as it is 2bytes per pixel, on a 5Mp CMOS, meaning approxiamtely 10,000bytes, leaving you with a 10Meg file. Include into this the remaining metadata etc and you are left with the correct filesize for the *.dng outputs from fcam.

Not sure why it is throwing up errors on the other programs you mention in your previous post but I always have (and probably always will) work(ed) in Photoshop....

Lowlight doesn't seem to save images anywhere, or if it does I can't find them... am I being stupid?

Same here, stock kernel no overclock no bless900.

To use the standard camera app after opening the lens you can depress the shutter button to activate the camera app.

The new FCam drivers don't seem to know anything about the lens cover sensor on the N900, so presumably they have somehow deactivated it when replacing the normal camera driver.

It's a shame it wasn't picked up as Nokia have apparently been working on this with the university guys - perhaps better N900/Maemo integration will come later (won't hold breath).

[Milhouse]

Lowlight doesn't seem to save images anywhere, or if it does I can't find them... am I being stupid?

Yes. :)

lowlight processes your pictures in the background, and it can take several minutes per photograph.

When the processing of each image is complete the jpg should appear in the MyDocs/.images directory (where they can be viewed in the Photos application).

[col37400]

ah ok. They aren't appearing in the images directory but maybe I'm not giving it enough time to process them.

[rotoflex]

I am also unsure if the process for lowlight or HDR has completed, and may be exiting before they are completed.

A status message of "Processing" and possibly "Completed" would be very useful.

[tzsm98]

It's good to get a feel for the community's experience with a new tool/toy. These bug discussions are interesting.

If you find a bug you can report it to the bug tracker for the application so it can be vetted, assigned and addressed.

https://garage.maemo.org/tracker/?group_id=1693

Is the bug page for part of the fCam application. Be sure the developers are aware of your unexpected experiences so this application can be molded into something that works as imagined.

Currently there only two reported bugs. One has to do with lack of feedback and the other with install issues when using the Enhanced Linux Kernel. .

Yes. In fact, in practical terms, this app is not really usable until some sort of status message is provided.

Especially as there is no way to switch to other applications and leave it to do its stuff in the background. You have to quit to use anything else on the phone.

[maxximuscool]

is it just me or after installed fcam-driver my N900 stock camera app taken pictures with more grain and light sensitive? Whereas the dark area will be blocks of black boxes and doesn't dethering properly?

I hope it is just me :(
If anyone experiencing this then I'll log the bug :) otherwise please move on!

[col37400]

I had the problem of opening the lens cover not activating the stock camera app today. It doesn't happen all the time. But I think it is related to the installation of Fcam so is a bug of some sort.

[toxaris]

Be aware.
I Unplugged my phone from the powercord this morning and notice that it was quite hot, or atleast warmer the usual.
Later today I notes that the battery drained very fast today so I started Conky to see it there was a process that might eating my phone. And yes HDRCapture did 100% CPU most of the time. And suddenly I remember that I used FCAM apps yesterday.
So when you have used some FCAM related apps, be sure to check processlist after.

[Ministeri]

fcams image browser is awesome.

It's way smoother and faster than default Maemo 5 Images app. Someone should replace default Images app with something like this. Swipe effect, zooming etc. are great!

[Milhouse]

And suddenly I remember that I used FCAM apps yesterday.
So when you have used some FCAM related apps, be sure to check processlist after.

Presumably by this you mean "I took a boat load of pictures with the hdrcapture app"?

As you've discovered each hdrcapture image takes a long while to process in the background. I never got a reply to my question as to whether FCam uses or can use any hardware acceleration but it could certainly use its help as the N900 battery probably won't last long enough to take more than a dozen hdrcapture images. Perhaps an option to delay background processing until the N900 is on AC power would be useful.

[andyph666]

is it not possible to view the pictures taken with fcamera? I've installed the fcam drivers, hdrcapture and lowlight but cant see where the viewer is? Thanks.

swipe up while in fcamera to view delete or share images if you dont have access to open dng files

swipe down to enable auto jpg

hdr pics go in camera, lowlight pics go in images -both as jpg, so should be automatically picked up from gallery

[col37400]

i keep getting notified of an update to the fcam drivers...but can't install it because of a conflict with the 'power users' kernel I also have installed.

[daperl]

Can it? Should be able to. The Standford class where this comes from did a project on this very subject.

Does it?

I think the answer is yes and no. If you're referring to JPEG creation on the dsp, I don't think they are. There just using Nokia's closed source libjpeg62 and it doesn't have any reference to /lib/dsp/jpegenc_sn.dll64P. But Nokia's closed source libjpeg62 does seem to be using NEON calls to help with the discrete cosine transform (DCT):

jpeg_fdct_ifast_neon
jpeg_idct_4x4_neon
jpeg_idct_ifast_neon

The debian version of libjpeg62 doesn't have these calls.

The jpg conversion doesn't seem to be a problem (the jpg images appear quickly etc, even when saving in RAW at the same time)

It's the background processing that appears as though it would benefit the most from hardware acceleration as this seems to be all CPU based - for instance, hdrcapture and lowlight both grind away in the background for sometimes minutes at a time and frankly kills the battery in short order.

POSSIBLE BUG:

PROBLEM: The notification LED next to the Screen stopped working after installing fcamera.
Other apps installed (related to camera) was livefocus and blessn900.
It still didnt work after uninstalling all of the above apps (incl fcam drivers).
the charging led doesnt even work when im charging no matter if its on or off... however... while restarting the phone i can see it blink one time in the before booting.



Other than that - MAGNIFICIENT APPLICATION! :)

[zimon]

Perhaps an option to delay background processing until the N900 is on AC power would be useful.
I agree! The fcamera interface would just tell there is some photos (HDR) which have been delayed and need to be processed in some later time.

Then command to finalize previously delayed works would be there somewhere. Manual command would be fine if automatic processing option is turned off, because the system cannot know if someone is about to fully charge the battery or just quickly get some extra juice on the road when the charger gets connected.

With HDR-photos, self timer with setable delay time is a MUST have feature. (Yes I have a tripod for N900.)

After installing the latest Fcam drivers/program from
app manager - install updates
Fcam wont start at all, Native camera app wont start at all,
"internal app error/driver error"
and WORST OF ALL, keybord lights are not working, as well as charge light error.

Uninstall and re boot only allows native cam app to operate, keybord lights are still out....:mad:

anyone else have this error, or awar of how to restore keybord ilumination?
I have found this:
http://talk.maemo.org/showthread.php?t=50766&highlight=fcam
still trying to figure it out.

[jean2323]

uninstall fcam and fcamera, remove the battery for some time and reinstall.

this worked for me, but i tried this scheme a few times till it worked
i've used apt-get in the end to reinstall app and drivers

[vignes_k]

i would love to have a time lapse feature with fcamera. Also is the 1s exposure time a limitation of fcam? If it can be extended to allow a longer exposure it will give new options for serious mobile photography. any thoughts of adding zoom functionality?

examples of some shots taken with a canon 450D may be a reality with a mobile camera.

[S0urcerr0r]

FIX :
i also FIXED the status led by turning off the phone and remove the battery for some minutes - like jean also mentioned before. just removing for a few seconds didnt work.

probably some areas of a hardware controller chip partially crashes. maybe the same chip that handles charging of the battery while the phone is off. maybe its a conflict between blessn900, live focus and fcamera that causes this problem.


however i still cant get fcamera to work. but the lowlight and hdr apps works nicely. ive tried uninstalling blessn900 and live focus, then reinstalled fcamera and drivers and its still the same

[pthomas22]

I also updated fcam yesterday anfd now the LED lights do not function.
Launching fcam fails and it also disables the native camera. A reboot gets the native camera back but there is a pretty major fail here on the latest drivers.

[jean2323]

i kept installing and rebooting, taking the battery off till it worked .
when it worked i followed this scheme:
i've installed the fcam drivers with apt-get install in terminal and then the fcamera again with apt-get

now it works

but the phone acts strangely lately ... i have issues with wifi, charging and the leds

[Rob1n]

I also updated fcam yesterday anfd now the LED lights do not function.
Launching fcam fails and it also disables the native camera. A reboot gets the native camera back but there is a pretty major fail here on the latest drivers.

I don't think it's the drivers. The new blessn900 version should be using the same drivers, and that works without any issues (plus the fcam authors have said there's been no code changes to the drivers in this release). The problem seems to be the fcamera app itself, and the LED activation code it's using.

[pthomas22]

Fcam also stops FrontView from working

[jean2323]

LEDs but starting too ... cause after it crushed ... reinstalled, the app won't start (blessn900 won't start either!) is this that makes one think that the drivers (or maybe something else that the 2 apps share) is the problem

[pthomas22]

Turning bluetooth on and then off seems to reset the LED's but you need to do it every time you use Fcam or recharge.

[CYPHERC]

i dont even know what is this app for, lol, someone told me it was for better pics, and i got it, and now i dont know how it works. lol

[col37400]

my phone's been acting a bit funny lately - slowing down and seizing up when it shouldn't. is there any reason to think that fcamera could be to blame?

[KlausRu]

I would also like to be able to extend the time of exposure to way more than 1 sec. Ideally I would suggest a real manual setting of exposure, an endless exposure which is just terminated by pressing the button a second time: first click to open the shutter, second to close it.
My goal are experiments with light painting.

A workaround would be a command line access to fcamera using all parameters as options. Maybe someone can help on this.

Thanks

[silent tim]

I've noticed that in low light, if the exposure is set to auto its set itself to 4 seconds if the iso is locked - its actually let me take quite decent pictures of stars in the sky

[KlausRu]

Thanks silent tim.
I've quickly tried your hint but without success. The exposure wouldn't get longer than 1 sec. I'm using PR1.2, standard kernel, current fcam+fcamera.
Let's keep trying

[donaggio]

I also updated fcam yesterday anfd now the LED lights do not function.
Launching fcam fails and it also disables the native camera. A reboot gets the native camera back but there is a pretty major fail here on the latest drivers.

Are there any news on those problems?

[ETalvala]

Hi all,

FCamera's use of the front LED is clearly conflicting with other uses of it. We didn't run into it here, but clearly other apps, or maybe bluetooth use, are doing similar things to what we are, and it confuses the microcontroller that runs the LEDs. And once the microcontroller goes down, it's not reset without a hard reboot (battery removal). We're not sure where the problem is yet, and we might just do a point release that disables the LED use until we sort it out.

We didn't actually change anything in the fcam-drivers codebase between the two releases, besides compiling a set for Titan's kernel and removing the package conflicts- if there are crashes now that didn't exist before, or if the built-in camera doesn't work anymore, those aren't driver-level problems.

If you do run into trouble, please submit bugs on our tracker, at
our Maemo garage project pages (https://garage.maemo.org/tracker/?atid=5974&group_id=1693&func=browse). It's hard for us to keep on top of all the Maemo talk threads, and we easily miss things.

for me the behavior is a bit different.
Fcamera, HDRcapture and LowLight all work okay, and the notification LED also works okay, no problems with all this.
But BlessN900 crashes each time or at least does not produce results or hangs in different ways.
The normal Camera app works okay too.

Hi all,

FCamera's use of the front LED is clearly conflicting with other uses of it. We didn't run into it here, but clearly other apps, or maybe bluetooth use, are doing similar things to what we are, and it confuses the microcontroller that runs the LEDs. And once the microcontroller goes down, it's not reset without a hard reboot (battery removal). We're not sure where the problem is yet, and we might just do a point release that disables the LED use until we sort it out.

Hopefully everything gets fixed. So are you saying that removing the battery for a hard reset fixes the front led problem? Because i flashed the EMMC and the problem still exist.

I too am having the same problem..usually after using BlessN900.

The method I use is to load the HealthCheck app and select "System Reboot" much easier than taking out and replacing the battery.

i have a problem

the fcam has some extera noise in my camera how i can fix it

i used it in night and in the lighting room "light"

can any one give me ex "script or command or any thing "?

because it is not give me good pics

thank you

Besides the full manual mode (aka B mode, where can keep exposing as long as you want), can we have additional compositing modes for long exposures, like for example timed exposures, compositing frame by frame with a given exposure time for each frame and an arbitrary formula for the combination (like, adding, subtracting, average, only brighter, only darker etc , including all the layer blending modes common in photo manipulation progs plus things like explicit math formulas and stuff) ?

Also, for HDR images, why is it restricted to only 3 pictures? Wouldn't it produce better images if there were more intermediary steps? Perhaps a combination of f-stops and the "sensitivity" (the ISO thing) thing would be needed in order to get more levels under some circumstances, would that be enough or the ISO thing just fakes it?

Also, how about a prog/mode to combine flash and natural shots keeping the best of each?

Why not just go to Xterminal and type: root
reboot -f

???

Way faster than loading Health Check app.

Does someone has an idea how to bind the camera shutter button to Fcamera app on default. I don't want the N900 standard camera app to launch when I open the camera cover or press the camera shutter button. So how to change the standard camera application in the N900?

[vignes_k]

would be great if fcam has a zoom feature as well as s feature to take time lapse images :)

my 2cents

Would it be possible to finetune the phase of the frames? (so we can have the frame always start when the scanline of the CRT we are trying to photograph is at the top, then tunning exposure time so it ends when the scanline is at the end, and then we can take several pictures with the screen contents evenly lit until the clocks start to drift apart)
