OK, I won't say it. LOL >>Does anyone know what is going on here? > >No, but with -d 1 much above -q 50 I get dropped frames. That's the main reason I stopped using lavrec for doing my recordings. My CPU just isn't fast enough to do 100% JPEG compression of incoming frames in real time, and I'm not willing to give up that quality. I use xawtv's streamer to do my recording, then run yuv2lav as a post-processing step. I've posted a patch that adds a -w option to yuv2lav, that allows audio to be added to the LAV files at the same time as the video. (I'll be putting it into CVS soon.) Here's the script I use to record all of my VCDs. ---------- #!/bin/bash renice 0 $$ streamer -r 29.97 -s 704x480 -t 3:00:00 -n ntsc -i S-Video -f 4mpeg \ -F stereo -b 64 -O stream.wav \ | yuvscaler -v 0 -M BICUBIC -O VCD -n n > stream.yuv echo renice 5 $$ yuv2lav -f a -q 100 -b 1024 -w stream.wav -s 30500 -o %02d.avi \ < stream.yuv rm -f stream.wav stream.yuv ---------- Ths -s option is something I haven't shown to anyone else yet; it tells yuv2lav to get rid of every 30,500th video frame, in order to get my audio to sync up with my video. (That's what you get when your audio device & video device aren't driven by the same crystal.)
