After fixing AV_PKT_DATA_SKIP_SAMPLES for reading vorbis packets from ogg,
the actual decoded samples become fewer. Three fate tests are failing:
fate-vorbis-20:
The samples in 6.ogg are not frame aligned. 6.pcm file was generated by
ffmpeg before the fix. After the fix, the decoded pcm file does not match
anymore. Ideally the ref file 6.pcm should be updated but it is probably
not worth it including another copy of the same file, only smaller.
SIZE_TOLERANCE is added for this test case.
fate-webm-dash-chapters:
The original vorbis_chapter_extension_demo.ogg is transmuxed to dash-webm.
The ref file webm-dash-chapters needs to be updated.
fate-vorbis-encode:
This exposes another bug in the vorbis encoder that initial_padding is not
correctly set. It is fixed in the previous patch.

Vorbis has priming samples at the beginning. If the initial_padding is not
set in the encoder, the total sample count will be one frame fewer than it
should be. The result is that we get a truncated version of encoding.
initial_padding should be set to the frame_size used in
vorbis_encode_frame().

Without end_trimming, the last packet will contain unexpected samples used
for padding.
This commit partially fixes#6367 when the audio length is long enough.
dd if=/dev/zero of=./silence.raw count=20 bs=500
oggenc --raw silence.raw --output=silence.ogg
oggdec --raw --output silence.oggdec.raw silence.ogg
ffmpeg -codec:a libvorbis -i silence.ogg -f s16le -codec:a pcm_s16le silence.libvorbis.ffmpeg.raw
ffmpeg -i silence.ogg -f s16le -codec:a pcm_s16le silence.native.ffmpeg.raw
ls -l *.raw
The original test case in #6367 is still not fixed due to a remaining issue.
The remaining issue is that ogg_stream->private is not kept during
ogg_save()/ogg_restore(). Field final_duration in the private data is
important to calculate end_trimming.
Some common operations such as avformat_open_input() and
avformat_find_stream_info() before reading packet will trigger ogg_save()
and ogg_restore().
Luckily, final_duration will not get updated until the last ogg page. The
save/restore mentioned above will not change final_duration most of the
time. But if the audio length is short, those reads may be performed on
the last ogg page, causing trouble keeping the correct value of
final_duration. We probably need a more complicated patch to address this
issue.

Frame size of Opus stream was previously presumed here to be 960 samples
(20ms), however sizes of 120, 240, 480, 1920, and 2880 are also allowed.
It can also alter on a per-packet basis and even multiple frames may be
present in a single packet according to the specification, for the sake
of simplicity however, let us assume that this doesn't occur.
Because the mFramesPerPacket field, representing the number of samples
per packet in the ffmpeg terminilogy, is the key factor in calculating
packet durations and all that follows from that (index, bitrate, ...),
it is crucial to get right.
Therefore, if the packet size is not available ahead of time (as it is in
the case of Opus), calculate an average from the stream duration once we
know how many packets there are and update the filed in the header.
This commit adds handling for cases where an error may occur, clearing
the allocated memory resources.

Its also a obscure choice (producing less nice images) that implementing it in the

The beginning of the private contexts of both the FLAC and the TAK
demuxer currently mimick FFRawDemuxerContext: A pointer to an AVClass
followed by the AVOpt-enabled field raw_packet_size. Said field is only
used by the demuxers' read_packet functions via
ff_raw_read_partial_packet(), which treats the private context as an
FFRaawDemuxerContext. Yet this is fragile, so better include a
FFRawDemuxerContext struct at the beginning of said demuxers' private
contexts.
