* avformat/movenc: Fix editlist with hybrid_fragmentedZhao Zhili2025-06-161-2/+7
| | | | | | | | | The segment_duration must not be set to zero when writing the moov atom for the second time. This is related to edit lists in standard MP4 files. Reviewed-by: Martin Storsjö <martin@martin.st> Signed-off-by: Zhao Zhili <zhilizhao@tencent.com>

* avformat/movenc: Fix flush fragmentZhao Zhili2025-06-011-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | The follow cmd output corrupted file before the patch: ffmpeg -f lavfi -i color=blue,trim=duration=0.04 \ -f lavfi -i anullsrc,atrim=duration=2 \ -movflags +empty_moov+hybrid_fragmented \ -frag_duration 1000000 \ -frag_interleave 1 \ output.mp4 1. first_track is the first track with track->entry != 0. As in the command above, video track (track index 0) has a single frame. When flush the second fragment, first_track is 1, the audio track. 2. write_moof = i == first_track, so write_moof is false for i = 0. 3. When mov->frag_interleave != 0, mov->mdat_buf != NULL, because it contains audio data. So avio_write is called before write_moof, that is, the data write before moof, and mov_finish_fragment executed with wrong mdat_start. 4. With normal fmp4 output, the error isn't obvious. With hybrid_fragmented, ffplay output.mp4 shows a lot of error messages. Signed-off-by: Zhao Zhili <zhilizhao@tencent.com>
* avformat/movenc: fix VVC encoding with leading picturesGabriel Hege2025-05-311-2/+2
| | | | | | | | | | | | The default behavior for VVenC (since v1.10.0) is to create an IDR with leading pictures for the first picture in decoding order (POC 32). This leads to FFmpeg generating an edit list with an empty entry, skipping the leading pictures. This patch fixes the calculation for the start_pts, while the DTS is negative (as produced by vvenc).

* avformat/movenc: disallow buggy flags combinationGyan Doshi2025-05-261-0/+6

* avformat/movenc: use stream indexes when generating track idsJames Almer2024-08-071-1/+5
| | | | | | | | | | | In some scenarios nb_tracks isn't the same as nb_streams, so a given id may end up being used for two separate streams. e.g. when muxing an IAMF track followed by a video track, if the IAMF track consists of several streams, the video track would end up having an id of 2, which may also be used by one of the IAMF streams.

* movenc: Add an option for resilient, hybrid fragmented/non-fragmented muxingMartin Storsjö2024-06-241-5/+57
| | | | | | | | | | | | | | This allows ending up with a normal, non-fragmented file when the file is finished, while keeping the file readable if writing is aborted abruptly at any point. (Normally when writing a mov/mp4 file, the unfinished file is completely useless unless it is finished properly.) This results in a file where the mdat atom contains (and hides) all the moof atoms that were part of the fragmented file structure initially. Signed-off-by: Martin Storsjö <martin@martin.st>

* movenc: Allow writing timed ID3 metadataMartin Storsjö2024-04-101-1/+48
| | | | | | | | | | | | | This is based on a spec at https://aomediacodec.github.io/id3-emsg/, further based on ISO/IEC 23009-1:2019. Within libavformat, timed ID3 metadata (already supported by the mpegts demuxer and muxer) is handled as a separate data AVStream with codec type AV_CODEC_ID_TIMED_ID3. However, it doesn't have a corresponding track in the mov file - instead, these events are written as separate toplevel 'emsg' boxes. Signed-off-by: Martin Storsjö <martin@martin.st>
