found the problem! in config.h there is a DEFAULT_VIDEO_DEVICE = "/dev/video" which under my system (2.4 kernel/redhat7.1) is /dev/video/video0 (anyone know if this is standard or an abberation) john > > > i just upgraded to redhat 7.1 and am now getting the message > "video device (/dev/video) open failed" > with the simpleTest app... > > WinTV card / bttv driver / Xawtv work just fine, > i tried changing the channel # in the simpletest.c to 0,1 and 2 > other settings seem to be set correctly (ie NTSC) > > any ideas? > john > > > > |

From: Robert Hinn <exodus@u ...............> Hi. As far as I know, it's the new standard that /dev/video is a directory instead of a device, so the video-device would now be called /dev/video/video0. I had the same problem on my system, too. Robert.
