Andreas Rheinhardt	b5968df9f0	avformat/matroskaenc: Don't reserve space for HDR10+ when unnecessary Do it only for video (the only thing for type for which HDR10+ makes sense). This effectively reverts changes to several FATE ref-files made in `bda44f0f39`. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	1 year ago
James Almer	bda44f0f39	avformat/matroskaenc: support writing Dynamic HDR10+ packet side data Signed-off-by: James Almer <jamrial@gmail.com>	2 years ago
James Almer	1c2a1e0750	avformat/matroskaenc: write a MaxBlockAdditionID element A non zero value is mandatory for Matroska if the track has blocks with BlockAdditions. Signed-off-by: James Almer <jamrial@gmail.com>	2 years ago
Andreas Rheinhardt	b468ddc75d	avformat/matroskaenc: Don't waste bytes to Write Tag length fields This is possible by using a dynamic buffer to write them; said dynamic buffer is (re)used and reset as appropriate. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	3 years ago
Andreas Rheinhardt	9f7e0b37ff	avformat/matroskaenc: Don't waste bytes on BlockGroup length fields This commit uses the new EbmlWriter API to write the length fields of the BlockGroup and its descendants that are themselves Master elements (namely BlockAdditions and BlockMore) on the least amount of bytes. This fixes regressions introduced when the special code for writing general subtitles was removed. Accordingly, the binsub-mksenc and matroska-zero-length-block FATE-tests have now been reverted back to their old state again; the advantages of this approach are evident with the matroska-vp8-alpha-remux test which up until now wrote all the length fields of all BlockGroups, BlockAdditions and BlockMore on eight bytes. Using the EbmlWriter API also allowed to improve locality in mkv_write_block(): E.g. both DiscardPadding as well as the BlockAdditional side-data are now directly used to add elements to the writer whereas the earlier code had to first check for whether a BlockGroup should be used and then check again (after the place where a BlockGroup would be opened if one were used) for whether there is DiscardPadding or BlockAdditional side-data to write.

Andreas Rheinhardt	03d31ef39c	avformat/matroskaenc: Remove special code for writing subtitles Once upon a time, mkv_write_block() only wrote a (Simple)Block, not a BlockGroup which is needed for subtitles to convey the duration. But with the introduction of support for writing BlockAdditions and DiscardPadding (both of which require a BlockGroup), mkv_write_block() can also open and close a BlockGroup of its own. This naturally led to some code duplication which is removed in this commit. This new code leads to one regression: It always uses eight bytes for the BlockGroup's length field, whereas the earlier code usually used the lowest amount of bytes needed. This will be fixed in a future commit. This temporary regression is also the reason for changes to the binsub-mksenc and matroska-zero-length-block fate tests.

Andreas Rheinhardt	0148e85c3c	avformat/matroskaenc: Don't waste bytes on SimpleTags length fields Also check the (user-provided) tags for being overlong; the earlier code had an implicit unchecked size_t->int conversion. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	3 years ago
Andreas Rheinhardt	b0d8310f76	fate/matroska: Add test for zero-length Block It furthermore tests the demuxer's handling of chained SeekHeads, level 1-elements after the Clusters and the muxer's capability of writing huge TrackNumbers as well as expanding the Cues' length field by one byte if necessary to fill the reserved space. It also tests propagation of metadata. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>	4 years ago
