Testing OpenCV, Video4Linux2 on colossus at Bryn Mawr College.
- Updated OpenCV from 1.0.0 to 1.1.0pre1
Running xawtv on Fedora9 you may get the following error:
$ xawtv -device /dev/video1 This is xawtv-3.95, running on Linux/i686 (188.8.131.52-78.2.41.fc9.i686) xinerama 0: 1280x1024+0+0 X Error of failed request: XF86DGANoDirectVideoMode Major opcode of failed request: 136 (XFree86-DGA) Minor opcode of failed request: 1 (XF86DGAGetVideoLL) Serial number of failed request: 65 Current serial number in output stream: 65
To avoid that error, use the -nodga flag:
xawtv -nodga -device /dev/video1
This may also initialize the camera correctly (which Pyro and OpenCV don't?).
OpenCV still crashes, but maybe not as often. See bugs:
