I've made a new grab_bdsbktr.c that could do with a bit of hammering. Anyone who wants to play can find the new code on ftp.sohara.org in /pub (or email me for a copy). Just replace the grab_bsdbktr.c in/usr/ports/graphics/ffmpeg/files with the one from the ftp site and rebuild ffmpeg. Changes: ======== Native YUV420P support from the bktr driver instead of YUV422 and convert (thanks go to Roger Hardiman for the info on how to do this), it seems to me that the video quality is better this way (which I did not expect). OTOH CPU usage is UP!, so I really want to hear about the video quality! New timer (usleep) based overrun detection, this should keep audio/video sync under almost all conditions. Let me know! There's a warning message printed when a signal is skipped, which I'll probably remove before asking for a commit. -- 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
