* avformat/oggparsevorbis: Avoid tmp bufs when parsing VorbisCommentAndreas Rheinhardt2021-08-28
| | | | | | | | | | | | | | | | | | | | | | | | A single VorbisComment consists of a length field and a non-NUL-terminated string of the form "key=value". Up until now, when parsing such a VorbisComment, zero-terminated duplicates of key and value would be created. This is wasteful if these duplicates are freed shortly afterwards, as happens in particular in case of attached pictures: In this case value is base64 encoded and only needed to decode the actual data. Therefore this commit changes this: The buffer is temporarily modified so that both key and value are zero-terminated. Then the data is used in-place and restored to its original state afterwards. This requires that the buffer has at least one byte of padding. All buffers currently have AV_INPUT_BUFFER_PADDING_SIZE bytes padding, so this is ok. Finally, this also fixes weird behaviour from ogm_chapter(): It sometimes freed given to it, leaving the caller with dangling pointers.

| | | | | | | | | These are auxiliary side-data functions, so they should have been switched to size_t in d79e0fe65c51491f9bf8a470bbe36fb09f3e1280, but this has been forgotten. Reviewed-by: James Almer <jamrial@gmail.com> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* oggdec: remove the oggparsedaala subdemuxerLynne2020-05-23
| | | | | | The Xiph foundation never standardized either Daala nor its mapping in Ogg, and all files that were created are undecodable without knowledge of the git hash.
* oggdec: add support for proper demuxing of chained Opus files and streamsLynne2020-04-30
| | | | | | Part of this patch is based on Paul B Mahol's patch from last year. This also allows for single-stream parameter/codec changes.

* lavf: add oggparsedaala and bump microRostislav Pehlivanov2015-10-21
| | | | | | | | | | | | | | | | | | | This commit introduces a parser for the current bitstream produced by Daala. It currently bears a large similarity with Theora, another codec produced by Xiph. While likely to change in the future, its basic format of packet parsing should remain fairly identical with its current structure. Once the bitstream freezes, there are a few probable simplifications that could be made. Also, the current version (major, minor and micro) is stuck at zero so it's unusable as a way to warn about possible incompatibilities. This will change once the bitstream freezes, however until then this file is strictly targeting the current git master of the reference encoder, libdaala. This file was developed independently at the same time by both myself and Vittorio Giovara, who used libav as a starting point. For fairness, and to prevent confusion and allegations, his name has been added to the copyright in the license header as well, and vice versa.

| * ogg: update event_flags with STREAM_/METADATA_UPDATED whenever metadata changes.Andrew Stone2014-08-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Originally, AVFormatContext and a metadata dict were provided to ff_vorbis_comment(), but this presented issues if an AVStream was being updated or the metadata on AVFormatContext wasn't actually being updated. To remedy this, ff_vorbis_stream_comment() explicitly updates a stream's metadata and sets any necessary flags. ff_vorbis_comment() does not modify any flags, and any calls to it that update AVFormatContext's metadata (just a single call) must also update AVFormatContext.event_flags after detecting any metadata changes to the provided dictionary, as signaled by a positive return value.

* | lavf/oggdec: check for begin-of-stream flag in case of chained streams.Clément Bœsch2012-09-22
| | | | | | | | | | | | | | | | | | | | | | | | Fix Ticket #1617, revealing a regression I introduced in 8f3eebd. We need to make sure no stream is added in between Ogg context save and restore operations (because it would likely lead to a mismatch between ogg->nstreams and AVFormatContext->nb_streams after the restore op). This is the reason the ogg->state check is added in ogg_new_stream(). Before this patch, checking for ogg->headers was preventing this: ogg->headers is always set before any ogg save/restore (though, it was also preventing from creating the stream when necessary).
