My kernels say BST, fanoush's say CEST and Nokia ones say EEST.
That's right; 100% sure here. One kernel with any normal multi-boot setup. (With the Linux flasher, I think you can boot any kernel; that might be a good way, if you just want to test a different kernel quickly...)

Well the dbus error comes from the alsa dsp plugin, I have submitted a patch for it :
https://garage.maemo.org/tracker/ind...id=81&atid=371
I have rebuild a package with this fix :
http://manupap1.free.fr/maemo/chinoo..._0.7_armel.deb

The good thing it's now with some other vlc fix I can heard my voice in the headset. :D

I will post new packages soon...

Sometimes I wish I could hit the "thanks" button multiple times on a post. This is magnificent. You're stealing all the fun stuff from the GSoC student. He's not going to have much to do. :D

Well, OK, there is this whole playback thing that needs some serious optimization...

EDIT: Installing your .deb requires a bit of forcing:

Quote:
sudo dpkg -i --force-conflicts osso-dsp-plugin-alsa_0.7_armel.deb

dpkg: regarding osso-dsp-plugin-alsa_0.7_armel.deb containing osso-dsp-plugin-alsa:
libasound2-plugins conflicts with osso-dsp-plugin-alsa
osso-dsp-plugin-alsa (version 0.7) is to be installed.
dpkg: warning - ignoring conflict, may proceed anyway !
EDIT2: Still getting the bus error, will wait (impatiently) for your new packages.

Effectively the osso-dsp-plugin-alsa package conflicts with the libasound2-plugins package but on my own tablet dpkg removed it cleanly before to install the dsp plugin.

I'm not sure the package is properly installed on your tablet because the dbus error should not happen anymore even with non fixed vlc debian packages.

You can try new packages here :
http://manupap1.free.fr/maemo/chinook/

Adding ":adev=default" to the v4l2 part of the command line should be enough to enable the sound capture.

There is still a lot of work to do :

I didn't succeed in transcoding the audio, this perhaps only a command line issue, I didn't try all the parameters.

I get a vlc crash with an unexpected "Bus error" with the followingl command :
Code:
qvlc v4l2:///dev/video0:chroma="UYVY":width=176:height=144:fps=5:adev=default

Here's what I'm getting when I try:

Sorry, me again...

OK, I was getting the bus error with --force-conflicts because it was actually not installing it:

Quote:
Unpacking replacement osso-dsp-plugin-alsa ...
Replaced by files in installed package libasound2-plugins ...
Setting up osso-dsp-plugin-alsa (0.7) ...
When I tried using

Code:
dpkg-deb -x osso-dsp-plugin-alsa_0.7_armel.deb  /
it does its thing silently, but then VLC does this:

Quote:
[00000001] main libvlc debug: translation test: code is "en_GB"
[00000353] dummy interface: using the dummy interface module...
dsp_protocol_open_node(): Could not open pcm device file /dev/dsptask/pcm_rec
alsa_dsp_prepare(): Error in send speech params data
[00000363] v4l2 demux error: Failed to read alsa frame (Input/output error)
[00000363] v4l2 demux error: Failed to read alsa frame (Input/output error)
That v4l2 demux / alsa error just repeats over and over, as log as the video is displayed.

This is very frustrating. Can you post your successful command line that played mic in your headphones?

EDIT: Oops. Forgot to install new VLC packages. Wait a bit...

Yes it should work much better with the new packages...
I have applied one patch for the speech error.

Oops I can not believe I missed this one.

No I was wrong*. I used a gst-launch pipeline to determine the acceptable resolutions, and 176x144 is one of them. That's not the problem.

I only get the bus error when trying to get audio working. What command line actually works?

*This happens a lot.

Re: Here is a working VLC Media Player!!
 
Here is the gstreamer pipeline script I use to test the camera and mic. This works to echo both cam and mic. When VLC can do this, I know that the cam and mic are both working.
Code:
gst-launch gconfv4l2src ! "video/x-raw-yuv,width=$1,height=$2,framerate=(fraction)$3/1" ! xvimagesink  dsppcmsrc ! "audio/x-raw-int,rate=8000,channels=1" ! dsppcmsink
you save it as a script, then test the camera parameters by running

Code:
gstest 176 144 8
Again, though, lokidor, I need to know what command line you used to get the mic to echo to your headphones. I cannot get it to work at all.
