Camera application cannot record video

[xiayi]

Run "cheese", select video and start recording.Try clicking "stop recording" but there's no response.

a fix for this is in http://bazaar.launchpad.net/~vcs-imports/cheese/trunk/revision/647

[Oliver Grawert (ogra)]

hmm, no, seems that doesnt help, the actual problem here is that the whole UI gets unresponsive as soon as video is recorded while the above fix is only for ending the record process (which cant even be triggered without being able to click the button)... (note that cheese is far from being ready for mainstream usage and we might not find the necessary fixes in time, the parties asking for its inclusion on the cmpc image were made aware of that since the beginning ....)

xiayi, there's no priority set on this bug - is this release-critical or not?

It looks like a fix for this involves incorporating gstreamer 0.10.20, which would be a very invasive and potentially destabilising change. As I understand it, the alternatives seem likely to be to drop cheese, or to document that it's currently necessary to force-quit the application.

Hi,
 Thank you for the analysis.
 It is critical. Cheese is the only application in this image that drives the hardware camera on CMPC. If its recording function is lost, so will be the camera's. I'll update its priority.
 And if cheese has to be dropped, we still need a substitute to make the camera run.

Best Regards
Xia Yi

Is this perhaps the GStreamer fix in question?

  http://webcvs.freedesktop.org/gstreamer/gstreamer/libs/gst/base/gstbasesrc.c?r1=1.160&r2=1.161

[Colin Watson (cjwatson)]

That's from http://bugzilla.gnome.org/show_bug.cgi?id=535218, by the way.

I believe I have this issue.

I start cheese, press video, press Start Recording
The image capture goes black and the app never responds.

I have to Force Quit.

apparently my firefox cant upload debdiffs atm ... this bug needs two fixes (and thus two SRUs), one for cheese, teh other for gstreamer
cheese: http://people.ubuntu.com/~ogra/cheese_2.22.3-0ubuntu2.debdiff
gstreamer: http://people.ubuntu.com/~ogra/gstreamer0.10_0.10.18-4ubuntu2.debdiff

[Oliver Grawert (ogra)]

both uploaded to hardy-proposed now ...

[Oliver Grawert (ogra)]

correction, teh cheese versioning needs to be ubuntu1.1, debdiff is at
http://people.ubuntu.com/~ogra/cheese_2.22.3-0ubuntu1.1.debdiff

[xiayi (yi-xia)]

hi, I saw sth like 80_fix_webcam.patch in the diff file. Is it the fix for #258110?

[Oliver Grawert (ogra)]

yes, but that patch also needs the gstreamer fixes that were uploaded...
as outlined on https://wiki.ubuntu.com/StableReleaseUpdates both packages wait for the quarantaine to expire and two positive comments from testers.
feel free to install them on an image from the hardy-proposed repository and confirm they work ... the faster we get positive comments on this bug the earlier i can roll the final image.
cheese is not used in normal ubuntu, so it is not that critical, but we need to avoid any regressions in gstreamer so that needs very tough testing...

[Martin Pitt (pitti)]

Accepted into -proposed, please test and give feedback here. Please see https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

[Martin Pitt (pitti)]

Please upload the fixes to intrepid ASAP, too.

[Oliver Grawert (ogra)]

confirming, code change is in cheese-2.24.0 in intrepid

[Oliver Grawert (ogra)]

code change confirmed to be in gstreamer0.10-0.10.21 in intrepid

[xiayi (yi-xia)]

Where could I get the patch for the bug? Is there a link to download?

[Martin Pitt (pitti)]

xiayi, see comment 14 for instructions: https://wiki.ubuntu.com/Testing/EnableProposed

[xiayi (yi-xia)]

Cheese is updated from 2.22.3-0ubuntu1 to 2.22.3-0ubuntu1.1. Now it's improved and videos can be saved. But it takes more than 1 minutes to stop recording after "stop" is clicked and user can no longer start recording after that until cheese is restarted.

[Martin Pitt (pitti)]

Both copied to hardy-updates.
