Bug description:
Binary package hint: cheese
== Regression details ==
Discovered in version: 8.10RC
Last known good version: 8.04.1
gstreamer-based apps (gstreamer-properties, cheese) doesn't show the
v4l2 video output.
cheese can configure webcam (Dell Inspiron integrated webcam) but it
does not provide any output. after some time the apps hang.
vlc can play with the webcam (including sound).
the hardware:
[ 11.835433] uvcvideo: Found UVC 1.00 device Laptop Integrated Webcam
(05a9:2640)
[ 11.835731] uvcvideo: Failed to query (135) UVC control 1 (unit 0) : -32
(exp. 26).
[ 11.893113] input: Laptop Integrated Webcam as
/devices/pci0000:00/0000:00:1a.7/usb3/3-1/3-1:1.0/input/input11
[ 12.025138] usbcore: registered new interface driver uvcvideo
Steps to Reproduce it:
1.- Start ekiga, you should get local video
2.- Start gstreamer-properties, you should get video at the tab and video
test button
3.- Start cheese and it would hang after a while
4.- Kill cheese, remove the uvcvideo (most probably this would happen with
other modules, pwc, gspca) driver and reload it again
5.- Try again with ekiga or gstreamer-properties, it would work
6.- Start cheese, go to properties and configure to the lowest resolution
available. Cheese would hang, kill it and it would start again.
Now you've got low resolution video
