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
