Debug log from Ubuntu 7.04. (486.85 KB, text/plain)

Description Filip Palm 2007-10-13 07:11:57 UTC 
When Gstreamer tries to initialize my webcam for the first time after a reboot it fails. I need to try one more time to get a picture.

gstreamer-properties:
1. Press "Test".
2. Fails with message that it could not make a test pipeline.
3. Press "Test" again, success!

1. Start cheese.
2. Fails with message that it could not find any webcam.
3. Start cheese again, success!

Other information:
Ubuntu 7.04 and Gstreamer 0.10.12
Comment 1 Tim-Philipp Müller 2007-10-13 14:04:07 UTC 
Could you run gstreamer-properties like this:

 $ GST_DEBUG=*:5  gstreamer-properties 2>dbg.log
 ... make it fail ...
 ... try again and make it succeed ...
 Quit or interrupt with Control-C
 $ gzip dbg.log

and attach the dbg.log.gz file?

Also, if you have a gutsy installation already: does it work with gutsy?

Comment 3 Filip Palm 2007-10-13 20:31:45 UTC 
It's the same problem with both versions of Ubuntu.
Comment 4 Wim Taymans 2008-11-11 14:41:09 UTC 
apparently grabbing the first picture takes 16 (!) seconds, which makes the test program time out.
Comment 5 Bastien Nocera 2008-11-11 15:00:31 UTC 
What device is that with? The kernel driver might be a bit broken...
Comment 6 Fabio Durán Verdugo 2011-06-28 23:43:16 UTC 
Filip can you reply the comment 5 ?
Comment 7 Akhil Laddha 2011-08-11 12:50:18 UTC 
Please feel free to reopen this bug if the problem still occurs with a newer version of GStreamer Core 0.10.35, Base Plugins 0.10.35, Good Plugins 0.10.30 stable release, tia.
