The grab_bsdbktr.c I wrote for ffmpeg uses the signalling available from the bktr driver to ensure proper frame capture (and runs at 25 or 30 fps or an exact fraction if the CPU can't keep up). The older MPlayer-0.90pre4 works fine with bktr too. -- C:>WIN | Directable Mirrors The computer obeys and wins. |A Better Way To Focus The Sun You lose and Bill collects. | licenses available - see: | http://www.sohara.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-multimedia" in the body of the message
