[FFmpeg-devel] [PATCH v10 0/8] Properly decode ogg metadata in ogg/{vorbis, flac, opus} chained bitstreams

[Romain Beauxis]

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

FATE samples for the new tests can be found here: https://www.dropbox.com/scl/fo/xrtrna2rxr1j354hrtymq/AGwemlxHYecBLNmQ8Fsy--4?rlkey=lzilr4m9w4gfdqygoe172vvy8&dl=0

## Changes since last version:
- Rebased against latest `master` to fix a merge conflict

Romain Beauxis (8):
  libavcodec/decode.c: intercept `AV_PKT_DATA_METADATA_UPDATE` packet
    extra data, attach them to the next decoded frame with the same PTS.
  tests: Add stream dump test API util.
  tests: Add chained ogg/vorbis stream dump test.
  libavformat/oggdec.h, libavformat/oggparsevorbis.c: Factor out vorbis
    metadata update mechanism.
  libavformat/oggparseflac.c: Parse ogg/flac comments in new ogg
    packets, add them to ogg stream new_metadata.
  tests: Add chained ogg/flac stream dump test.
  libavformat/oggparseopus.c: Parse comments from secondary chained
    streams header packet.
  tests: Add chained ogg/opus stream dump test.

If one takes all money from those who grow wealth and gives it to those who
do not grow wealth, 10 years later, almost the same people who where wealthy
will be wealthy again, the same people who where poor will be poor again.

If a bugfix only changes things apparently unrelated to the bug with no
further explanation, that is a good sign that the bugfix is wrong.

I'm confused.

You asked me to push the fixed patchset to a branch, which was done
here: https://github.com/toots/FFmpeg/pull/2/commits/500f56ed270a4a6053ff51408f775a8b4be5210e

Should I push a new version on here?

It passes here without the trailing whitespace

I suggest to remove them, because some editors remove trailing whitespace
some people git setups do too. It could cause pain to people
if in c/h files trailing whitespace is forbidden but here its
used.
Also as this is ffmpeg output, maybe the code outputting trailing
whitespace should be fixed

thx

Rewriting code that is poorly written but fully understood is good.
Rewriting code that one doesnt understand is a sign that one is less smart
than the original author, trying to rewrite it will not make it better.
