In some places it's obvious that a different frame is displayed. Example: seek to 46%. Person walking across the screen jumps several times before walking normally. Even if the video is paused when you seek, then when play is started again the same effect is seen. Reference: http://crbug.com/568336 After playing with this for a while, it appears to be related to commit 4ab56667594842283dc5ae07f0daba2a2cb4d3af. My guess is that when seeking the first frame displayed is the one at the start of the fragment, but then the code catches up to the correct position quickly. Removing the call to either mov_read_sidx() or mov_seek_fragment() in libavformat/mov.c "fixes" the problem. In Chromium, the effect is different. It gets the following frames out of order, so the video jumps around quite a bit. Observation video attached to the crbug listed above, if you're interested. -- Ticket URL: <https://trac.ffmpeg.org/ticket/6402> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

X265vfw codec generates "HEVC" not recognized by FFMPEG so file is unopenable. As a workaround I'm changing AVIs FourCC but it would be better if FFMPEG directly support it (besides I don't have a fourCC changer for MKV files). Is it posible to modify FFMPEG so as to also accept opening HEVC fourCC? Thanks! -- Ticket URL: <https://trac.ffmpeg.org/ticket/7110> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

I can use videotoolbox to encode video on both GPU's but can't select which one to use. When iGPU is enabled, this one is always used. But when I disable the iGPU in bios, the Vega64 card is used. I've encoded several video's and for h264, I want to use the HD630 iGPU because it produces better quality. But for HEVC, the Vega64 produces much beter quality and is 4 times faster. So, it would be very nice if it is possible to switch between the available GPUS. -- Ticket URL: <https://trac.ffmpeg.org/ticket/6853> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
