Hi. I've been spending my week trying to capture with my Matrox G400-TV card and hopefully take advantage of the hardware MJPEG encoder. Thus far I have successfully installed the mgavideo drivers and mjpegtools. XawTV works super for playback, but nasty for recording thereby creating a need to use mjpegtools. Using lavrec like so:
lavrec -f a -i n -d 1 -q 80 -R l -U /video/capture.avi I get good results with very few dropped frames - eleven drops total for the hour of video from a ten-year-old VHS tape. I'm excited about this so far. But the thing is that I like a gui - especially for video - so I'm anxious to use LVS. After installing the rpm (v. 0.1.7-1) and running studio one of two things happens: 1. LVS starts up but shows split and garbled video from the VCR, no matter how I change the options to use NTSC, etc. and/or 2. The video displays properly but when I try to initialize a capture I get an error window telling me: Lavrec failed with the following error: [lavrec] Error opening video-device (/dev/video): Device or resource busy Then I notice that if I try going back to the command line lavrec, I get these errors: ++ WARN: [lavrec] Unable to set negative priority for main thread ++ WARN: [lavrec] Pthread Real-time scheduling for main thread could not be enabled ++ WARN: [lavrec] Unable to set negative priority for audio thread. ++ WARN: [lavrec] Pthread Real-time scheduling for audio thread could not be enabled. **ERROR: [lavrec] Error opening output file /video/x.avi: Oy. Now I'm in trouble. But I find if I uninstall both rpms for mjpegtools and lvs, and reinstall only mjpegtools then lavrec works for me once again and I'm back to where I began. I'm not really sure what to do at this point. Any thoughts? __________________________________________________ Do you Yahoo!? Yahoo!
