[FFmpeg-devel] [PATCH v5 0/7] Remove chained ogg stream header packets from the demuxer

[Romain Beauxis <romain.beauxis@gmail.com>]

## Changes since last revision:
* Added mechanism to pass new extradata when decoding ogg packets.
* Use it to pass new ogg/vorbis setup data to the vorbis decoder.
* Add checks for format change when parsing subsequent ogg/vorbis and
  ogg/opus chained streams

Romain Beauxis (7):
  libavformat/oggdec.h: Document packet function return value.
  libavformat/oggdec.{c,h}: Implement packet skip on packet return value
    of 1
  ogg/opus: implement header packet skip in chained ogg bitstreams.
  ogg/flac: implement header packet skip in chained ogg bitstreams.
  libavformat/oggdec.{c,h}: Add new_extradata, use it to pass extradata
    to the next decoded packet.
  ogg/vorbis: implement header packet skip in chained ogg bitstreams.
  libavformat/oggdec.h: Change paket function documentation to return 1
    on header packets only.
