[v4l2src] my webcam is not working anymore
Last modified: 2007-11-15 21:53:11 UTC
Since I switched from Feisty (gst-plugins-good 0.10.5) to Gutsy (gst-plugins-good 0.10.6) I can't use my webcam anymore. It's a Logitech QuickCam Pro 5000 (driver uvc-video [1]). When I try using gstreamer-properties I got this error: gstreamer-properties-Message: Error running pipeline 'Video for Linux 2 (v4l2)': Could not get buffers from device '/dev/video0'. [v4l2src_calls.c(1025): gst_v4l2src_capture_init (): /pipeline0/v4l2src3: error requesting 0 buffers: Cannot allocate memory] Here is the debug output I got using GST_DEBUG_NO_COLOR=1 GST_DEBUG=5: http://projects.collabora.co.uk/~cassidy/gst.log.gz Feel free to ask for output using other debug options of course. I started to track this problem with the maintainer of the uvc-video driver. See [2] and replies. It seems v4l2src tries to use the v4l2 read method instead of mmap (read is currently not yet implemented in uvc-video). Thanks for your help [1] http://linux-uvc.berlios.de/ [2] https://lists.berlios.de/pipermail/linux-uvc-devel/2007-September/002099.html
this should be fixed in CVS. Can you try?
Indeed. Ubuntu package was updated and it works fine now. Thanks!
