Sorry I didn't mean to top-post, I thought that meant 'replying to a post earlier in the thread', not 'putting text in the top of a post'. Hopefully this one is less rude :) Anyhow yes, -mc 1 and -demuxer lavf -nocorrect-pts works for the sample there but it's seriously low bitrate. I've uploaded a different sample in Matroska (still h264 and AC3) with a higher bitrate at http://www.charlieg.net/downloads/tv.mkv. The actual bitrate is variable but I think it peaks around 18mbps. I'm still getting 'Your system is too SLOW to play this' messages and A-V desyncs; here's what I've tried: - mplayer -vo xv -mc 1 -demuxer lavf -nocorrect-pts tv.mkv (SLOW message) - mplayer -vo xv -mc 1 tv.mkv (A-V desync) - mplayer -vo xv -demuxer lavf -nocorrect-pts tv.mkv (SLOW message) - mplayer -vo vdpau -vc ffh264vdpau -mc 1 -demuxer lavf -nocorrect-pts tv.mkv (SLOW message and A-V desync) - mplayer -vo vdpau -vc ffh264vdpau -mc 1 tv.mkv (same) - mplayer -vo vdpau -vc ffh264vdpau -demuxer lavf -nocorrect-pts tv.mkv (same) Note that none of these are doing any deinterlacing. I tried the following options: mplayer -vo vdpau:deint=4 -vc ffh264vdpau -mc 1 -demuxer lavf -nocorrect-pts -lavdopts skipframe=nonref tv.mkv And I avoided the SLOW message and A-V desyncs, but playback was quite choppy. I assume this is due to 'skipframe=nonref' but if this is the result I don't see it as a solution. I can create another sample with a lower bitrate if 18mbps is too high (it seems like it, but Wikipedia says 1920x1080 @ 30fps can max at 20mbps...), or I can use CBR if you think that's causing a problem. Thanks for your help, -Charlie _______________________________________________ MPlayer-users mailing list MPlayer-users@xxxxxxxxxxxx https://lists.mplayerhq.hu/mailman/listinfo/mplayer-users
