Binary package hint: cheese
Using Jaunty on a sony vaio laptop VGN-FE31H, cheese crashes when trying to record a video with the following message:
"** Message: Error: Le flux ne contient aucune donnée.
gsttypefindelement.c(786): gst_type_find_element_activate (): /GstPlayBin:play/GstDecodeBin:decodebin0/GstTypeFindElement:typefind:
Can't typefind empty stream
** (cheese:13098): WARNING **: could not generate thumbnail for /home/valerie/Vidéos/Webcam/2009-05-16-210337.ogv (video/ogg)
"
More specifically:
- The video is displayed fine
- When the record button is pressed, the image turn greenish and the program crashes.
The only way to abort the program is to kill the process.
I successfully could record video on the same laptop using wxCam with the type of image set to YUYV (in case it helps). Also gstreamer-properties doesn't return any error, and displays the video correctly if I use l4v2. If I try using l4v1 the image turns green and freezes.
Here is the version of cheese used:
apt-cache policy cheese
cheese:
Installé : 2.26.0-0ubuntu1
Candidat : 2.26.0-0ubuntu1
Table de version :

Finally I'd like to add that the exact same problem occured to another person:
http://forum.ubuntu-fr.org/viewtopic.php?pid=2644824
Update: I found that I could not record sound using the default app bundled with jaunty (can't rememeber the name). After playing a while with Alsa settings I finally got it working. One of the configuration problems was that the recording source was set to PCM instead of the internal microphone.
When that worked I found that I could record video with sound with no problems using cheese. So it seems that Cheese did hang when it couldn't capture the audio. This shouldn't happen, instead a warning could be displayed saying that no audio will be captured and explaining how to fix this.
I can confirm this issue... When i try to record a video with cheese and a Microsoft LifeCam Cinema, cheese crashes immediately without a traceout on the shell...
$ LANG=C cheese
^C
After i kill the process and restart Cheese I get these messages
$ LANG=C cheese
** (process:5041): WARNING **: Couldn't change nice value of process.

I think they are caused by the bad video file. My system says about the webcam the following...
