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.
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.
Well, OK, there is this whole playback thing that needs some serious optimization...
EDIT: Installing your .deb requires a bit of forcing:
EDIT2: Still getting the bus error, will wait (impatiently) for your new packages.

osso-dsp-plugin-alsa (version 0.7) is to be installed.
dpkg: warning - ignoring conflict, may proceed anyway !

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 :
lokidor

Sorry, me again...
OK, I was getting the bus error with --force-conflicts because it was actually not installing it:
When I tried using
it does its thing silently, but then VLC does this:
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...

I have applied one patch for the speech error.

I notice that the camera is VERY particular about the dimensions you give it. It has to be exactly 1.3 ratio, so use 192x144 or 176x132.

I only get the bus error when trying to get audio working. What command line actually works?
*This happens a lot.

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.
you save it as a script, then test the camera parameters by running
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.

Code:

Code:
gstest 176 144 8
