Re: [FFmpeg-user] h264_vaapi missing frames

Actually I spoke too soon. It's definitely dropping frames still. For example. https://s.natalian.org/2018-03-28/1522205981.mp4.log https://s.natalian.org/2018-03-28/1522205981.mp4 ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org

Re: [FFmpeg-user] h264_vaapi missing frames

Thank you Moritz! Damn, I feel like a fool. ;) Unfortunately Mark's suggestion doesn't seem to have an impact. As you hopefully can see here: https://s.natalian.org/2018-03-23/1521768226.mp4 The mouse still doesn't move smoothy across the screen. Hence I feel it's dropping frames!
