I wasn't test for that error on the grounds that there may not be a tuner or any audio (camera input for example) so it isn't a failure if opening the tuner doesn't work. I've added a warning message for the next update. GWK> Hmm, the mplayer/mencoder from ports didn't want to grab at all when GWK> I tried it in 4.6-R. It said something about no matching colorspace. There are very few codecs (ie. divx only I think) in mencoder that can handle the capture format used and there is (at the moment) no support for switching capture format. That's the itch that got me writing capture for ffmpeg in the first place :) GWK> With ffmpeg, encoding as mjpeg and no audio compression, I can GWK> capture full resolution with just occasional jerkyness. Nice, I have been getting great results (low CPU and no jerkiness) with "-vcodec mpeg1video -me zero -intra -b 7200" on my AMD2000. Turning on motion estimation pushes average CPU usage to 65% and at the peaks I lose frames. GWK> All this is with your recent one-line bktr patch for sync generation. Now that's the news I've been waiting to hear. That makes two thumbs up and no complaints.
