#3267(undetermined:new): MP4 chapter metadata issues: weird/superfluous text streams

#3267: MP4 chapter metadata issues: weird/superfluous text streams -------------------------------------+------------------------------------- Reporter: y3kcjd5 | Type: defect Status: new | Priority: normal Component: | Version: undetermined | unspecified Keywords: mp4 | Blocked By: chapters metadata | Reproduced by developer: 0 Blocking: | Analyzed by developer: 0 | -------------------------------------+------------------------------------- If I try to create an mp4 file with chapters in it and I do not include '''-map_metadata:c -1''' in my command line, the resulting file will, for some bizarre reason, get a weird text stream tacked on to it invisibly. This stream doesn't show up anywhere in the creation log, and cannot be edited by ffmpeg in any way (trying to modify or add to its metadata has no effect). but a subsequent ffprobe will reveal its presence. My best guess is that this 'stream' contains the chapter metadata, but I am confounded as to why chapter metadata should show up in its own little fake stream while all other metadata is handled transparently.

Moreover, as previously mentioned, the only way to prevent this weirdostream from appearing is to include '''-map_metadata:c -1''' (or '''-map_metadata -1''') in the command line. This means that even if there is no actual chapter metadata, one such superfluostream is (aggravatingly) still generated by default (as demonstrated above). -- Ticket URL: <https://trac.ffmpeg.org/ticket/3267> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker
