QuickTime_Player start input.mov from this frame: [https://ibb.co/Hp2HFR6] But after ffmpeg conversation it looks like this: [https://ibb.co/kMz65Fh] Looks like a problem with elst/media_time and how ffmpeg interprets this: 1. In QuickTime_File_Format_Specification media_time is '''DT''' value. {{{ The edit list atom provides the initial DT value if it is nonempty (nonzero). }}} 2. In ISO IEC 14496-12 media_time is '''CT''' value. {{{ The Edit List Box provides the initial CT value if it is non‐empty (non‐zero). }}} From the code we can see that the second variant is used in ffmpeg, but then what about the existing media_time (it is set not to a specific PTS of frame, but in the middle) in attached file and how to interpret the next note (ISO IEC 14496-12): {{{ Edits are not restricted to fall on sample times. This means that when entering an edit, it can be necessary to (a) back up to a sync point, and pre‐roll from there and then (b) be careful about the duration of the first sample — it might have been truncated if the edit enters it during its normal duration. If this is audio, that frame might need to be decoded, and then the final slicing done. Likewise, the duration of the last sample in an edit might need slicing. }}} How to reproduce: {{{ % ffmpeg -i input.mov output.mp4 ffmpeg version - any, last tested - 4.3.2 built on 2021-02-27 }}} -- Ticket URL: <https://trac.ffmpeg.org/ticket/9139> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#9105(ffmpeg:new): Cannot set dispositions for subtitle streams inside MKV other than Default and Forced

#9105: Cannot set dispositions for subtitle streams inside MKV other than Default and Forced -------------------------------------+------------------------------------- Reporter: droid-xx | Type: defect Status: new | Priority: normal Component: ffmpeg | Version: Keywords: ffmpeg | unspecified disposition metadata | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- I'm not sure whether this is a bug or a feature but I'm filing this since the documentation on disposition types is lacking details. If this is a feature, then there's probably some internal checking by ffmpeg to determine whether the disposition type given by the user can be applied to the selected stream. So obviously if you pass a disposition type of "attached_pic" to a subtitle it won't make any sense, hence nothing will change in the output disposition-wise (although there's no error or warning displayed to inform the user about this, and the documentation doesn't state which dispositions apply to which types of streams). However there are at least 2 more dispositions that can be set for subtitle streams: "karaoke" (for ass/ssa which are designed as karaoke subtitles) and "hearing_impaired" (for SDH subtitles). This works for the third subtitle track inside an .mkv with a total of 3 subtitle streams: {{{ ffmpeg -i input.mkv -map 0 -c copy -disposition:s:2 forced output.mkv }}} This won't work (disposition is ignored with no errors/warnings): {{{ ffmpeg -i input.mkv -map 0 -c copy -disposition:s:2 hearing_impaired output.mkv }}} {{{ ffmpeg -i input.mkv -map 0 -c copy -disposition:s:2 karaoke output.mkv }}} -- Ticket URL: <https://trac.ffmpeg.org/ticket/9105> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
