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	a04c917399	avformat/matroskaenc: Don't waste bytes on ChapterAtoms length fields Also check the (user-provided) metadata tags for being too long. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	3 years ago
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	750631b098	avformat/matroskaenc: Pass dispositions through unchanged by default Up until now, the Matroska muxer did not use the dispositions it is given as-is; instead it by default overrode the disposition of the first track of a kind (audio, video, subtitles) if no track of this kind has the default disposition set. And up until recently, it also enforced by default that no more than one track of each kind be marked as default. The rationale for the former is that there are lots of containers which lack the concept of default streams, so that it is not uncommon for no stream to be marked as default at all; the rationale for the latter was that up until recently, it was dubious whether the Matroska specification allowed more than one default stream for track type (e.g. mkvmerge disallowed it). It was this point which led to the implementation of the above mentioned behaviour inspired by mkvmerge. Yet the Matroska specifications have changed and now explicitly allow to set more than one track of each type as default, so that the main reason of not using the dispositions as-is was rendered moot. Therefore this commit changes the default to pass the disposition through. The matroska-mpegts-remux FATE-test has been updated to still use the old "infer" mode so that it is still covered by FATE; the matroska-zero-length-block test has also been updated to cover the infer_no_subs mode. The references for lots of other FATE tests needed to be updated because of a newly added FlagDefault element with value zero (whereas a FlagDefault with value 1 needn't be coded at all, as it coincided with the default value of said element).

Guangyu Sun	b53738bf90	fate/oggvorbis: Fix tests after fixing AV_PKT_DATA_SKIP_SAMPLES After fixing AV_PKT_DATA_SKIP_SAMPLES for reading vorbis packets from ogg, the actual decoded samples become fewer. Three fate tests are failing: fate-vorbis-20: The samples in 6.ogg are not frame aligned. 6.pcm file was generated by ffmpeg before the fix. After the fix, the decoded pcm file does not match anymore. Ideally the ref file 6.pcm should be updated but it is probably not worth it including another copy of the same file, only smaller. SIZE_TOLERANCE is added for this test case. fate-webm-dash-chapters: The original vorbis_chapter_extension_demo.ogg is transmuxed to dash-webm. The ref file webm-dash-chapters needs to be updated. fate-vorbis-encode: This exposes another bug in the vorbis encoder that initial_padding is not correctly set. It is fixed in the previous patch.

Andreas Rheinhardt	4ebfc13c33	avformat/matroskaenc: Don't ignore tags of chapters written late The Matroska muxer writes the Chapters early when chapters were already available when writing the header; in this case any tags pertaining to these chapters get written, too. Yet if no chapters had been supplied before writing the header, Chapters can also be written when writing the trailer if any are supplied. Tags belonging to these chapters were up until now completely ignored. This commit changes this: Writing the tags belonging to chapters has been moved to mkv_write_chapters(). If mkv_write_tags() has not been called yet (i.e. when chapters are written when writing the header), the AVIOContext for writing the ordinary Tags element is used, but not output, as this is left to mkv_write_tags() in order to only write one Tags element. Yet if mkv_write_tags() has already been called, mkv_write_chapters() will output a Tags element of its own which only contains the tags for chapters. When chapters are available initially, the corresponding tags will now be the first tags in the Tags element; but the ordering of tags in Tags is irrelevant anyway. This commit also makes chapter_id_offset local to mkv_write_chapters() as it is used only there and not reused at all. Potentially writing a second Tags element means that the maximum number of SeekHead entries had to be incremented. All the changes to FATE result from the ensuing increase in the amount of space reserved for the SeekHead (21 bytes more). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>	5 years ago
Andreas Rheinhardt	5b6e164b4b	avformat/matroskaenc: Don't waste bytes on length fields Several EBML Master elements for which a good upper bound of the final length was available were nevertheless written without giving an upper bound of the final length to start_ebml_master(), so that their length fields were eight bytes long. This has been changed. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>	5 years ago
Andreas Rheinhardt	2e92e1fb27	fate/matroska: Add test for chapters, Vorbis and WebM DASH Moreover, putting the Cues in front of the Clusters by reserving space in advance is also tested. The new capability of using ffprobe during a remux/transcode test are used here for information about the chapters. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>	5 years ago
