No objection to the patch, but you were the one who added the access to
st->codecpar, so that needs an explanation in the commit message.

This codec alternatingly skips and changes existing pixels.
A second 16bit parameter in the FOBJ header indicates how to do
the pixel changes: either by specifying a LUT in the codec datastream
or by adding a constant value to the pixel.

Hello all,
avformat_find_stream_info() calls av_freep() on FFStream::info, which
will cause a segmentation fault if it is called more than once on the
same AVFormatContext (assuming it still has at least one of the
AVStreams from when it was called previously).
Is this intentional and should
Same test as for ogg/opus.
Samples and output for both tests are available here:

In this case, the secondary chained ogg/flac header packets are already visible
before the changes.

This is the code for the main utility used to dump chained streams and
test for decoded metadata in subsequent patches.

These changes parse ogg/opus comment in secondary chained ogg/opus
streams and attach them as extradata to the corresponding packet.
They can then be decoded in the opus decoder and attached to the next
decoded frame.
libavformat/oggparseopus.c: Parse comments from
secondary chained ogg/opus str
This the same changes as done with ogg/opus: parse comments in secondary
chained ogg/flac streams, attach them as packed extradata, decode and
attach them to the next decoded stream in the flac decoder.
libavformat/oggparseflac.c: Parse ogg/flac comments in
new ogg packets, add them to ogg stream
These changes make it possible to access the initial header packets of
secondary chained ogg/opus bitstreams.
libavformat/oggparseopus.c: Parse extradata from
secondary chained streams header packet.
libavformat/oggdec.c: Do not force ogg stream header parsing on
secondary ogg/opus chained strea
This adds the test to confirm that secondary chained ogg/opus streams
are properly decoded.
Using the test output, we can confirm that secondary stream header
packets are properly passed down and that the new metadata are properly
parsed.
Output before the changes:

This is a series of patches to allow proper decoding of ogg metadata
in chained ogg/flac and ogg/opus streams.
