webcam doesn't work at 640x480, only resolutions lower than 176x144

[mon]

After the recent updates, cheese doesn't work at all. Before I could take photos, but couldn't record video. And in hardy I could do both.

If I launch it with -v:

cheese -v

And the window is white and if I close the app it hangs.

I don't know if it's relevant, but in /var/log/dmesg I could read this:

If I change the resolution to 176x144 or lower it works.

The laptop is a dell xps m1330.

Hi

I think it's not cheese fault:

This works:
gst-launch-0.10 -v v4l2src ! video/x-raw-yuv,width=176,height=144 ! ffmpegcolorspace ! xvimagesink

but increasing the size of the capture window fails, but --verbose doesn't show anything.

[mon (javiermon-deactivatedaccount)]

The bug can be reproduced with gst-launch0.10, so the bug is not in cheese.

[Alexander Hunziker (alex-hunziker)]

I have the exact same behaviour with an external USB webcam from Logitech (model "Quickcam Deluxe for Notebooks"). It uses the UVC driver. It works fine in Ekiga and other apps not accessing it over GStreamer. It also worked fine with GStreamer under Hardy. Now I also experience the limitation to 176x144.

[mon (javiermon-deactivatedaccount)]

Confirmed by Alexander

[mon (javiermon-deactivatedaccount)]

With today's updates I can launch a first screen with a size of 640x480:

But cheese still doesn't work.

[mon (javiermon-deactivatedaccount)]

Ok, something interesting, If I launch gst-launch it works, then if I launch cheese it doesn't and subsequent launches of gst-launch doesn't work either. weird

Hi

mplayer also works:
mplayer -fps 15 tv:// -tv driver=v4l2:device=/dev/video0

[mon (javiermon-deactivatedaccount)]

The bug seems to affect only cheese

[Jonathan Ernst (jonathan.ernst)]

Same problem here. The webcam works fine in Skype and Ekiga (I guess because of the poor resolution used there). But not in cheese unless I select 176x144 resolution.

This was working fine in Hardy and is a regression in Intrepid for me.

gst-plugins-good0.10 0.10.10.3-1ubuntu1 has fixed the issue here.

[Alexander Hunziker (alex-hunziker)]

fixed for me as well

[mon (javiermon-deactivatedaccount)]

Alexander or enyone else, could you please see if you have this bug?

https://bugs.launchpad.net/ubuntu/+source/cheese/+bug/277997

If so, confirm it?

thanks

[mon (javiermon-deactivatedaccount)]

Apparently the reapply of the patch breaks cheese in this laptop.

This patch that was accidentaly dropped in lastes upload breaks the webcam in cheese.

[Shawn vega (svega85-gmail)]

I have this same bug with a Dell inspiron 1420

[Pedro Villavicencio (pedro)]

not a cheese bug then, more like a gstreamer one.

[Alexander Hunziker (alex-hunziker)]

Again chesse doesn't work for me - was the problem reintroduced by the latest sync of gstreamer? Can sombody confirm? Here, pure GStreamer works, but Cheese fails, while Cheese had been working a few days ago.

[mon (javiermon-deactivatedaccount)]

I think the bug is introduced with gstreamer support for libv4l, since the patch was dropped in a recent upload and when reapplied the bug came back. I don't now why since gst-launch does work with lastest gstreamer upload, but cheese doesn't.

I've writen about this in this other bug report:
https://bugs.launchpad.net/ubuntu/+source/libv4l/+bug/260918

[Marco Boneff (neffscape)]

Same bug on my XPS M1530, the problem seems to affect only Cheese. It is a clear regression from Hardy, I hope this will be fixed ASAP.

Thanks for your bug report, This seem to be a a dup for bug#290506. Any further comments are welcomed in bug #290506.
