cheese hangs on startup

[Tom Badran]

Binary package hint: cheese

When i start cheese it just gets as far as opening a blank window and hangs (doesnt crash, just freezes and does nothing, ever). This camera does works fine with ekiga, canoraram and even kstars.

Output of cam from lsusb:

Bus 007 Device 006: ID 0471:0311 Philips PCVC740K ToUcam Pro [pwc]

Added bug to gstreamer too and pasting in console output. If you need any more info or want me to try any gstreamer piplines just give the command line to try and i'll add more.

Hopefully cheese 0.2.2-0ubuntu3 fixes this. Please test it once it is available from the repositories.

[Tom Badran (tom-badran)]

Afraid 0.2.2-0ubuntu3 makes no difference with this particular camera. Setting back to new (not sure thats the correct state, correct me if wrong)

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please try to obtain a backtrace following the instructions at [WWW] http://wiki.ubuntu.com/DebuggingProgramCrash and upload the backtrace (as an attachment) to the bug report. This will greatly help us in tracking down your problem.

We also have to figure out if this error happens in cheese or in gstreamer. Thanks in advance.

I cant add a backtrace, if you read the report, there is no crash, it just freezes on startup and does nothing.

[Sebastien Bacher (seb128)]

you can get a backtrace of the hang, that will give some indication of where it's waiting

[Áron Sisak (asisak)]

Thank you for your bug report. This bug has been reported to the developers of the software. You can track it and make comments here: http://bugzilla.gnome.org/show_bug.cgi?id=476830

This seems to have been fixed with recent uploads of gstreamer.

Cheese hangs on startup here on Hardy. Should i use this bug report or start new one?

CamStream works fine. But, when playing with camStream, i could hang the computer too when i tried to set the resolution to VGA. Using QCIF (default) and SIF screen size in CamStrem worked OK.
