Please describe the problem: The video output went blank when I tried to change the resolution to 640x480. The output also showed an error: libv4l2: error allocating conversion buffer Steps to reproduce: 1. Started cheese with 800x600 resolution, working. 2. Change resolution to 600x480 Actual results: Video output went blank. Expected results: Video output to display at 640x480. Does this happen every time? Yes. Other information: Complete output: draco@laptop:~$ cheese (cheese:8128): GStreamer-WARNING **: pad source:src returned caps which are not a real subset of its template caps (cheese:8128): GStreamer-WARNING **: pad source:src returned caps which are not a real subset of its template caps (cheese:8128): GStreamer-WARNING **: pad video_source:src returned caps which are not a real subset of its template caps (cheese:8128): GStreamer-WARNING **: pad video_source:src returned caps which are not a real subset of its template caps libv4l2: error allocating conversion buffer
It's a known issue, if you are using Ubuntu Intrepid you can fix it enabling intrepid-proposed repository and upgrading kernel and libv4l. Otherwise just install libv4l >= 0.5.7 from your distribution repositories. *** This bug has been marked as a duplicate of 566212 ***
