it works now ! thanks :D

Re: fCamera and Titans kernel...
 
Sorry for getting confused. If I already have the Titan kernel I just need to uninstall BlessN900, install the Titan fCam driver then FCamera right? I shouldn't have to touch the kernel right?

I had that too, before any kernel upgrade. Simply decided to make my life difficult. Turns out it was a busted rootfs. A fsck and a battery removal later it started humming. Not even a reflash.

Re: fCamera and Titans kernel...
 
well, i did all of that and i cannot see why i would use the fcamera instead of the intergrated one!


takes horrible pictures, at least inside. i will have to try outside today.

ndi 2010-07-29 18:53
Re: fCamera and Titans kernel...
 
Inside, use lowlight or HDR. They both get me miles over the Nokia default cam.

Indoor use low-light settting as was mentioned earler. A few other nice features. I have only used it for a few minutes but here is what I think:

a) histogram. You may think the white wavy thing at the bottom is annoying but it is sometimes very useful in helping you determine good exposure. Especially when you're outside and can't tell because the sun is too bright, having the histogram is nice.
b) point focus. That's just all sorts of awesome. I wish it could stay permanently on the screen though and I could just move it around without the AF button selected
c) Manual control over just about everything.
d) swipe up for settings and swipe down for gallery. Genius. No extra real estate needed to get to these.

Stuff I'm not so sure about
e) RAW - Unless you are into photography and really into the best image quality you won't care. I just tested it and I'm not convinced they're shooting RAW. I'm going to start another thread but for now I'm calling BS.

Advantage of the integrated camera:
f) exposure compensation. I like the total manual control that fCamera gives but without exposure compensation its a little less useful.

These thoughts are just from 5 minutes of tinkering with it.

From my POV, the bottom line is that the integrated camera is decent for what it does. fCamera has good features and great potential. When that potential gets realized fCamera will beat the integrated camera, I'm certain. For now I think this will be the realm of enthusiasts at least for a few more revs.

Re: fCamera and Titans kernel...
 
Oh, and another reason to use fCamera is that the red light doesn't go on. :-)

BTW, fCamera works great, but I have a few issues. My phone updated and it saw an titan fcamera driver update. I tried to download it and it said it had a conflict with the power kernel. Is there anything I need to do? Thanks.

ndi 2010-07-30 08:30
Re: fCamera and Titans kernel...
 
The issue is being worked on. Don't force the upgrade.

I thought the new drivers are being held back? Are you using fapman?

Great. No, not using fapman, just the regular app updater. I'll just wait until the dust settles, but wanted to make sure I didn't miss any steps. Thanks.

does anybody know about a method to hold/lock titan's fcam-drivers other than
Code:
echo fcam-drivers hold | dpkg --set-selections
so that the blinking yellow icon not always notifies you about fcam-drivers_1.0.5-2?

ndi 2010-08-02 19:32
Re: fCamera and Titans kernel...
 
Ignoting the update stops the blinking until next verson.

I have (created and) edited the /etc/apt/preferences file, and pinned the Titan's version like that
Code:
Package: fcam-drivers
Pin: version 1.0.5-1
Pin-Priority: 1001
as suggested elsewhere in the forums.

Re: fCamera and Titans kernel...
 
...ok - now that we have Titans v38 kernel - what does it mean regarding the fcam-drivers?

xuggs 2010-08-03 16:20
Re: fCamera and Titans kernel...
 
^kernel38 doesn't seem compatible with the latest fcam drivers. If you have updated to kernel38 then fcam drivers install will give you a conflicting error.

titan 2010-08-03 16:24
Re: fCamera and Titans kernel...
 
there is no need to upgrade to v38, see

boxkillor 2010-08-03 16:36
Re: fCamera and Titans kernel...
 
damn so how can i get back to v37 then?

titan 2010-08-03 16:52
Re: fCamera and Titans kernel...
 
there is also no need to downgrade to v37 (unless you find serious bugs)

boxkillor 2010-08-03 16:54
Re: fCamera and Titans kernel...
 
whoops okay thanks titan, so i have to wait until multiboot updates too, cause i cant boot into maemo now like regulary by only pressing 1. (If i press 0 in multiboot, it loads maemo without the Ckernel in default and besides i cant load any profile like ideal :/)

ryanl33x1511 2010-08-03 19:16
Re: fCamera and Titans kernel...
 
same on me i cant boot to maemo after update to v38 using multiboot and i have to press 0, boot to default kernel. Is there a way we can get back to v37 or like normal with multiboot? I think the problem is that multiboot didnt recognize the v38, i still can see the booting option with v37.

boxkillor 2010-08-03 19:30
Re: fCamera and Titans kernel...
 
yeah right you can see in the tut,(where u get to know how to install nitdroid ,) a file of multiboot which only recognizes v37. with pressing 0 i will get maemo to boot, but only with the default kernel :/, so no more OC for me :x

ryanl33x1511 2010-08-03 19:50
Re: fCamera and Titans kernel...
 
i fix the problem. follow the post from me at multiboot thread.

what do i need to do to use fcam-drivers and still use the titan kernel? i got v38 titan kernel running now.

Looks like v38 is running smoothly. Phone is a little bit heavier with the added headers but I'll manage;) Saw references to v39 files. Will that be an update of interest to those who used the enhanced kernel or another developer interest update?

sponka 2010-08-03 23:30
Re: fCamera and Titans kernel...
 
v39 is out & running. FCamera (&lowlight &HDR capture) work with titan's fcam driver 1.0.5-1.

Still, can't find any changelog, yet :)

smartypants 2010-08-03 23:38
Re: fCamera and Titans kernel...
 
Where can i find titan's fcam driver?

sponka 2010-08-04 00:16
Re: fCamera and Titans kernel...
 
http://n900.tannerlab.com/kernel/fcam/

Download, install as root with "dpkg -i fcam-drivers_1.0.5-1_armel.deb".

FCamera and other apps can be installed normally via App Manager.

titan 2010-08-04 08:37
Re: fCamera and Titans kernel...
 
v39 merely adds a kernel-power-bootimg package which could be useful for multiboot.
users should just stick with v37

maartenmk 2010-08-04 08:46
Re: fCamera and Titans kernel...
 
What about a compatible version of the 1.0.5.2 fcam drivers?... I can live with ignoring the update in the app manager, but I believe the RAW output is fixed for use outside of Adobe programs.
Or are compatible drivers imminent, now that the v38 kernel is out?

...I think nobody can stick on v37 when there is a v39 available; we are just curious nerds :rolleyes:

gabby131 2010-08-04 10:20
Re: fCamera and Titans kernel...
 
@titan

but we can update to v39 even if we dont wish to dual boot right?

ndi 2010-08-04 10:39
Re: fCamera and Titans kernel...
 
I'm not from around here but could you switch to human versioning, e.g. 37u, 38d, 39d, with d being developer only builds so we can conveniently ignore d builds?

giannoug 2010-08-04 11:20
Re: fCamera and Titans kernel...
 
Thats why he have 3 repositories. Use the extras repo if you are not a developer or just curious!

titan 2010-08-04 12:30
Re: fCamera and Titans kernel...
 
@ndi: v39 is only in extras-devel (unstable software). just disable the catalouge and you'll only see v37 from extras (stable).
@gabby131: yes

@maartenmk: now it's the fcam developers' job to build updated modules for the kernel.
Their drivers are independent and everything for building them is now provided by the repository.
I don't want to release a new kernel everytime they update their code.

Agreed. And I believe they said they would, so it should be a temporary problem. It just seemed to be not too much work to compile the -2 drivers, as a temporary solution. (but I don't know how much work it actually is, I'd try myself if I knew how).

Probably, but I would hate to be inbetween those times when Apple and the Jailbreakers are fighting the update game. Granted I think most jailbreakers wait until the jailbreak time handles the new Apple updates. But it only takes one potential "phone call" home to Apple to deem your device jailbreaked. And once is all it takes to invalidate your warranty (even if it's not a software issue).

But again this is all speculation, Apple hasn't shown their hand yet (besides refusing service if you tell them your device is jailbroken).

Re: fCamera and Titans kernel...
 
I haven't installed any of the fcam related software into my N900. Are the current versions compatible with the v37 kernel that I could just download fcam from app manager and not experience any problems?

No, see post #108 of this thread.

We're having a little trouble doing this. It seems like built versions of the kernel scripts that are present in kernel-headers (genksyms, modpost, etc) aren't present in kernel-power-headers. Am I missing something? I added a bug to the kernel-power-headers bug tracker in case this was just an oversight.

This is what I do in scratchbox to compile fcam-drivers against the stock kernel:

Code:
apt-get source fcam-drivers
apt-get install kernel-headers
cd fcam-drivers_1.0.5-2
make KERNELDIR=/usr/src/kernel-headers
a bunch of .ko files are produced.

This is what I did in scratchbox to try and compile our fcam-drivers against the enhanced kernel headers

Code:
apt-get source fcam-drivers
apt-get install kernel-power-headers
cd fcam-drivers_1.0.5-2
make KERNELDIR=/usr/src/kernel-power-headers
.. I get an error message about scripts/genksyms/genksyms being absent.

If I try to build the scripts like so:

Code:
make -C /usr/src/kernel-power-headers scripts
I get errors about missing include files. Looks like path issues trying to build the scripts from the headers package. Let me know if I'm doing something silly.

Edit: This is with v39. I have extras-devel and extras-testing enabled in scratchbox.
