Comment 26 for bug 93417

@ Brad Johnson
Just wanted to thank you for suggesting the use of vloopback. I just had a long video conversation with someone using Ekiga. I went with:
./resize /dev/video0 /dev/video1 352x288 176x144 rgb24

@all
In order to get better video quality I had to pass some gain parameters to the gspca module on load:
modprobe gspca GRed=512 GBlue=512 GGreen=512 force_rgb=0

I also tried the patch mentioned earlier. Still got cropping. Luckily this vloopback is at least a temporary solution :)

I didn't get to test with skype yet. What applications are people here using for testing the video cropping? I tend to go back and forth with ekiga, camorama, gqcam, and spcaview. That last one works the best and has no cropping issues. It also gives lots of useful info about your camera. Here's what mine shows:
