Re: [ANNOUNCE] Mirror
 

Thanks for that screenshot, matteone. It shows that the resolution of the front-facing camera may be the limiting factor.

To improve the quality of the image, perhaps the application can be modified to use the main camera. Of course the difficulty with that approach is that you can't see the screen while you're pointing the main camera at your face. But if you have a small mirror with you, you can position it so that you can see the N900 screen.

That looks close to 160 pixels. Try the following:

Re: [ANNOUNCE] Mirror
 

Same problem as always, daperl:

...could not negotiate formate.... check your filtered caps, if any....

As soon as you try to tidy up the output of the camera, it gorks.

EDIT: Setting it to ... ! video/x-raw-yuv,width=640 ! ... works, but it looks exactly the same.

Re: [ANNOUNCE] Mirror
 

Ok this isn't stretched anymore, but it still has the dark band:

gst-launch-0.10 v4l2src device=/dev/video1 ! "video/x-raw-yuv,pixel-aspect-ratio=(fraction)1/1" ! ffmpegcolorspace ! videoflip method=4 ! xvimagesink force-aspect-ratio=true

Re: [ANNOUNCE] Mirror
 

The dark band problem is deeper, either electronics or kernel driver level. It's there even I don't use gstreamer at all (=direct v4l2)

Re: [ANNOUNCE] Mirror
 

just an observation.

you want to use a small mirror in your possession to hack together an app supposed to work as a mirror?

isn't that a little redundant ?

Re: [ANNOUNCE] Mirror
 

In case some devs wants to track progress or make their own packages, I opened a garage project for this 'app' (talk about waste of resources :) ). The address is https://garage.maemo.org/projects/mirrorapp/

Re: [ANNOUNCE] Mirror
 

precisely! :D

(or, as they say on slashdot, "whoosh!")

Re: [ANNOUNCE] Mirror
 

Ever tried to take a look at the back of your head with a single mirror ? Can get tricky ! :D The solution is simple though, use TWO N900s and display the main cam image on the OTHER unit. Now THAT is a PUSH project right there :D

Re: [ANNOUNCE] Mirror
 

Ok, so here's how to get rid of the dark band. Use "videocrop" to crop it away!

The new pipeline to produce a properly sized image with no dark band:

gst-launch-0.10 v4l2src device=/dev/video1 ! "video/x-raw-yuv,pixel-aspect-ratio=(fraction)1/1" ! ffmpegcolorspace ! videoflip method=4 ! videocrop right=122 ! xvimagesink force-aspect-ratio=true

Re: [ANNOUNCE] Mirror
 

I just installed mirror 1.0-2 and it installed libspeex1 gstreamer0.10-plugins-good-extra, but when I run it I get:

something is missing?

anidel

EDIT: forgot to say that I've installed it via apt-get install mirror

Re: [ANNOUNCE] Mirror
 

How about swapping out v4l2src for v4l2camsrc.

Re: [ANNOUNCE] Mirror
 

Or use one N900, but have it plugged in to an external monitor.

Re: [ANNOUNCE] Mirror
 

Does /dev/video0 have this problem?

Also, please try v4l2camsrc. I just looked at the source, it's plenty different than v4l2src.

Re: [ANNOUNCE] Mirror
 

Ok, last pipeline. This one crops the top and the bottom so it fills the whole mirror window:

gst-launch-0.10 v4l2src device=/dev/video1 ! "video/x-raw-yuv,pixel-aspect-ratio=(fraction)1/1" ! ffmpegcolorspace ! videoflip method=4 ! videocrop top=60 bottom=160 right=122 ! xvimagesink force-aspect-ratio=true

EDIT: v4l2camsrc looks identical to v4l2src :(

Re: [ANNOUNCE] Mirror
 

Can we add a zoom feature so you can dial into that pimple? (Perhaps the swirly zoom from the browser ;) )

Re: [ANNOUNCE] Mirror
 

yep, you're missing gstreamer-tools (fixed in 1.0-3)

Re: [ANNOUNCE] Mirror
 

No, video0 works just fine (and has a lot better quality)

Re: [ANNOUNCE] Mirror
 

Thanks, some other update installed it, as it was already installed when I ran (now) apt-get install gstreamer-tools...

Anyway, it's working fine.
It's quite fast, but yes, the aspect ratio is to be fixed.

No way to take snapshots? :)

Re: [ANNOUNCE] Mirror
 

The zoom feature wouldn't be too hard, just crop the picture more and the remaining area will be hardware scaled to fill the screen.

Re: [ANNOUNCE] Mirror
 

Guys

I'm sorry to report a Portrait use-case at last !!!:D

Re: [ANNOUNCE] Mirror
 

If you're gonna zoom and stuff, I think it's time to wrap camerabin in a gui. If I had an n900, I would probably start with the attached gtk/gst Python script from here.

Re: [ANNOUNCE] Mirror
 

I already started wrapping it in a pinch of python after connys remarks as a prospective v2, but will certainly take a look.

Re: [ANNOUNCE] Mirror
 

Redundant is bad. Recursive is divine ;)

Re: [ANNOUNCE] Mirror
 

Good news everyone !

Apparently the vertical band problem was a firmware issue that is already fixed in the upcoming firmware, and is confirmed to work OK with mirror.

Re: [ANNOUNCE] Mirror
 

If only we could get an OTA!!!

so many bug fixes and no more firmware updates :(

Re: [ANNOUNCE] Mirror
 

Btw, you may also want to have a look at this interesting piece of code:

Re: [ANNOUNCE] Mirror
 

I guess this widget would be great also if you think you are being followed just hold the n900 a little to the left of you and so you can see behind you. Every spy needs this.

Re: [ANNOUNCE] Mirror
 

As if to announce: "hey, suspicious person following me, here's a £500 device for you to grab".

Re: [ANNOUNCE] Mirror
 

I basically ported that to Python.

Re: [ANNOUNCE] Mirror
 

I was hoping to see some cropping in the latest version... I guess you can leave the dark band in there for now, since that will be fixed, but crop the top and bottom to match the screen's aspect ratio, so that the user's face isn't stretched.

Re: [ANNOUNCE] Mirror
 

The next version will be a 2.0, which is a python script, so I can actually call it an app without blushing. It will contain all the mentioned goodies and hopefully please the testers so it has at least a remote chance of getting the 10 karma required for extras :)

Re: [ANNOUNCE] Mirror
 

I've attached a compiled FREMANTLE_ARMEL version of the camerabin directory from gst-plugins-bad0.10-0.10.13-git209/tests/examples.

Inside the camera directory you should be able to type:

./gst-camera

It's a shell script that I think runs the gst-camera binary that's inside .libs.

Maybe one of you n900 guys could give it a try and let us know what you see.

EDIT:

Here's a screen shot from my hacked x86 version:

Attachment 4476

I think the bottom slider is for zooming.

Re: [ANNOUNCE] Mirror
 

gunzip cb.gz just produces a file called cb...?

EDIT: Ok, it's a TAR. When I "tar xvf cb" it expands into a directory called "camerabin".

Re: [ANNOUNCE] Mirror
 

daperl: The script is designed to be run inside scratchbox, and it just doesn't like being run on a real device. I replaced a bunch of scratchbox-specific stuff, but it still doesn't work, and I can't figure out what's going on. It seems to delete .libs/lt-gst-camera and then attempts to run it. What's up with that?

Re: [ANNOUNCE] Mirror
 

how short are u on karma?

Re: [ANNOUNCE] Mirror
 

Maybe just go inside the .libs directory and run the gst-camera executable.

cd .libs
./gst-camera

Re: [ANNOUNCE] Mirror
 

./gst-camera: line 1: syntax error: "(" unexpected

Re: [ANNOUNCE] Mirror
 

Woops, I attached the i386 stuff by mistake. I'll get back to you.

Re: [ANNOUNCE] Mirror
 

Here, try this one.
