| * 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.

* | subtitles: introduce ASS codec id and use it.Clément Bœsch2013-04-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, we have a AV_CODEC_ID_SSA, which matches the way the ASS/SSA markup is muxed in a standalone .ass/.ssa file. This means the AVPacket data starts with a "Dialogue:" string, followed by a timing information (start and end of the event as string) and a trailing CRLF after each line. One packet can contain several lines. We'll refer to this layout as "SSA" or "SSA lines". In matroska, this markup is not stored as such: it has no "Dialogue:" prefix, it contains a ReadOrder field, the timing information is not in the payload, and it doesn't contain the trailing CRLF. See [1] for more info. We'll refer to this layout as "ASS". Since we have only one common codec for both formats, the matroska demuxer is constructing an AVPacket following the "SSA lines" format. This causes several problems, so it was decided to change this into clean ASS packets. Some insight about what is changed or unchanged in this commit: CODECS ------ - the decoding process still writes "SSA lines" markup inside the ass fields of the subtitles rectangles (sub->rects[n]->ass), which is still the current common way of representing decoded subtitles markup. It is meant to change later. - new ASS codec id: AV_CODEC_ID_ASS (which is different from the legacy AV_CODEC_ID_SSA) - lavc/assdec: the "ass" decoder is renamed into "ssa" (instead of "ass") for consistency with the codec id and allows to add a real ass decoder. This ass decoder receives clean ASS lines (so it starts with a ReadOrder, is followed by the Layer, etc). We make sure this is decoded properly in a new ass-line rectangle of the decoded subtitles (the ssa decoder OTOH is doing a simple straightforward copy). Using the packet timing instead of data string makes sure the ass-line now contains the appropriate timing. - lavc/assenc: just like the ass decoder, the "ssa" encoder is renamed into "ssa" (instead of "ass") for consistency with the codec id, and allows to add a real "ass" encoder. One important thing about this encoder is that it only supports one ass rectangle: we could have put several dialogue events in the AVPacket (separated by a \0 for instance) but this would have cause trouble for the muxer which needs not only the start time, but also the duration: typically, you have merged events with the same start time (stored in the AVPacket->pts) but a different duration. At the moment, only the matroska do the merge with the SSA-line codec. We will need to make sure all the decoders in the future can't add more than one rectangle (and only one Dialogue line in it obviously). FORMATS ------- - lavf/assenc: the .ass/.ssa muxer can take both SSA and ASS packets. In the case of ASS packets as input, it adds the timing based on the AVPacket pts and duration, and mux it with "Dialogue:", trailing CRLF, etc. - lavf/assdec: unchanged; it currently still only outputs SSA-lines packets. - lavf/mkv: the demuxer can now output ASS packets without the need of any "SSA-lines" reconstruction hack. It will become the default at next libavformat bump, and the SSA support will be dropped from the demuxer. The muxer can take ASS packets since it's muxed normally, and still supports the old SSA packets. All the SSA support and hacks in Matroska code will be dropped at next lavf bump.

* | lafv/matroska: add A_OPUS/EXPERIMENTAL codec name.Nicolas George2013-01-16
| | | | | | | | | | | | | | | | | | The exact packing of Opus inside Matroska is not finalized. Use A_OPUS/EXPERIMENTAL as codec name, like mkvtoolnix. The A_OPUS name stays to let ffmpeg open files it has produced until now, but newly produced file use the EXPERIMENTAL version. Once the spec is stabilized it will be possible to consider options to ensure compatibility with these files.

* | matroska: Mark S_TEXT/UTF-8 as Subrip encoded subtitles.Philip Langdale2012-08-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While not explicitly stated in the specs, the original author has stated that S_TEXT/UTF-8 is expected to be text using Subrip markup, but without Subrip in-band timing. So, now that we have a decoder that conforms to this expectation, let's use it. Note that this change will impact tools that use libavformat. If they expect srt subtitles to have CODEC_ID_TEXT, they must be adjusted to expect CODEC_ID_SUBRIP. The actual content is, obviously, unchanged. Signed-off-by: Philip Langdale <philipl@overt.org>
