2020-05-23oggdec: remove the oggparsedaala subdemuxerLynne
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.
2020-04-30oggdec: add support for proper demuxing of chained Opus files and streamsLynne
Part of this patch is based on Paul B Mahol's patch from last year. This also allows for single-stream parameter/codec changes.
2016-08-03avformat/oggdec: Fix integer overflow with invalid ptsMichael Niedermayer
If negative pts are possible for some codecs in ogg then the code needs to be changed to use signed values. Found-by: Thomas Guilbert <tguilbert@google.com> Fixes: clusterfuzz_usan-2016-08-02 Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
2015-10-21lavf: add oggparsedaala and bump microRostislav Pehlivanov
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.

2014-08-13ogg: update event_flags with STREAM_/METADATA_UPDATED whenever metadata changes.Andrew Stone
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.

2012-09-24ogg: calculate the start position once all the headers are parsedLuca Barbato
The fisbone packets can be muxed in any order as long the last one comes before the first data packet.
2012-09-24ogg: check that the expected number of headers had been parsedLuca Barbato
Not having the header for a codec is a tell-tale of a broken file.
2012-09-22lavf/oggdec: check for begin-of-stream flag in case of chained streams.Clément Bœsch
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).
