dcpomatic/src/lib/ffmpeg_examiner.h, branch main DCP-o-matic DCP tools https://git.carlh.net/cgit/dcpomatic/atom?h=main 2025-10-15T20:33:26Z Disable use of stream IDs if there are duplicates, rather than rewriting. 2025-10-15T20:33:26Z Carl Hetherington cth@carlh.net 2025-10-14T15:02:15Z urn:sha1:2d8d05c2e7ad67ebac2ff250670a219a891d09ca It turns out that FFmpeg decoders (e.g. flv, see FFmpeg 25faaa311a74efdfdc4fed56996d7338ed807488) check stream IDs and sometimes create new streams if they see one that they didn't see before. If we change stream IDs we break this. Here we try to use stream indices in cases where the IDs are duplicated. We also account for the case where a new stream appears during examination. This wasn't covered by tests until the FFmpeg commit mentioned above, were the flv decoder creates a new stream during examination of boon_telly.mkv.

Make DCPExaminer::size() optional and deal with the consequences. 2024-02-21T17:48:53Z Carl Hetherington cth@carlh.net 2024-02-21T09:47:38Z urn:sha1:3ffd0163026be24e5373e0674c3301ed37546e44 This means we can fix the case of a VF having no known size in a nice way, in turn fixing problems caused by the fix to #2775.
