* avformat/matroskadec: Add support for FlagOriginalAndreas Rheinhardt2021-03-02
| | | | | | | | | | | | | | | | Needs a CountedElement in order to distinguish the case of the element not being present and the element being present with a value of zero. (It has been argued by Ridley Combs that one should only ever use the AV_DISPOSITION_DUB field for audio tracks. Yet given that there is no definition for the disposition flags, one can also interpret it to mean that e.g. a subtitle track is meant to be used with the dubbed audio track or the original audio track. This commit interprets this flag in this sense, which also allows to maintain it on remuxing.)

* avformat/matroskadec: Add support for FlagHearing/VisualImpairedAndreas Rheinhardt2021-02-22
| | | | | | | | | | Given that our disposition flags provide no way to distinguish the cases of "track is unsuitable for hearing impaired users" and "it is unknown whether the track is suitable for hearing impaired users" we do not need to use a CountedElement for these flags.

* avformat/matroskadec: Add support for FlagCommentaryAndreas Rheinhardt2021-02-22
| | | | | | | | | | Hint: Matroska actually provides a way to distinguish the cases of "track is no commentary track" and "it is unknown whether the track is a commentary track", but our disposition flags do not. Therefore we need not use a CountedElement. Reviewed-by: Ridley Combs <rcombs@rcombs.me> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

| * matroskadec: export cover art correctlywm42015-04-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Generally, libavformat exports cover art pictures as video streams with 1 packet and AV_DISPOSITION_ATTACHED_PIC set. Only matroskadec exported it as attachment with codec_id set to AV_CODEC_ID_MJPEG. Obviously, this should be consistent, so change the Matroska demuxer to export a AV_DISPOSITION_ATTACHED_PIC pseudo video stream. Matroska muxing is probably incorrect too. I know that it can create broken files with an audio track and just 1 video frame when e.g. remuxing mp3 with APIC to mkv. But for now this commit does not change anything about muxing, and also continues to write attachments with AV_CODEC_ID_MJPEG should the muxer application have special knowledge that the Matroska is broken in this way.

* | WebM muxer writes WebVTT subtitle trackMatthew Heaney2013-07-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Matroska muxer now allows WebVTT subtitle tracks to be written while in WebM muxing mode. WebVTT subtitle tracks have four kinds: "subtitles", "captions", "descriptions", and "metadata". Each text track kind has a distinct Mastroska CodecID and track type, as described in the temporal metadata guidelines here: http://wiki.webmproject.org/webm-metadata/temporal-metadata/webvtt-in-webm When the stream has codec id AV_CODEC_ID_WEBVTT, the stream packet is serialized per the temporal metadata guidelines cited above. The WebVTT cue is written as a Matroska block group. The block frame comprises the WebVTT cue id, followed by the cue settings, followed by the cue text. (The block timestamp is synthesized from the cue timestamp.) Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
