02e7dbf5ad adpcm_ima_ws: fix stereo decoding 
Stereo ADPCM IMA WS is planar for VQA version 3 and 2-sample interleaved for
VQA version 2.

220506d23f avcodec: add a new codec_id for CRYO APC IMA ADPCM. 
The stereo layout and extradata is significantly different from that in
Westwood IMA ADPCM, so a separate codec_id is warranted.

According to Multimedia Wiki documentation, the frame rate is not always 15,
and the actual value can be found in the header.

them.

1381e9bc92 lavc: postpone the removal of AVCodecContext.request_channels. 
Although it has been deprecated for a long time, its intended
replacement (request_channel_layout) is not actually used anywhere, so
request_channels is currently the only way to access that functionality.

fc85729458 mxfdec: Do not parse slices or DeltaEntryArrays.

f028d4d1c3 mxfdec: hybrid demuxing/seeking solution 
This uses the old demuxing code for OP1a and separate demuxing code for OPAtom.
Timestamp output is added to the old demuxing code.

The seeking code is made to seek to the start of the desired EditUnit only,
from which the normal demuxing code takes over (if OP1a). This means we
do not use delta entries or slices, only StreamOffsets. OPAtom seeking
basically works like before.

This also makes D-10 seeking behave the same way as OP1a and OPAtom. In other
words, we allow seeking before the start or past the end for D-10 too.

Based on several patches by Tomas Härdin <tomas.hardin@codemill.se> and
Reimar Döffinger <Reimar.Doeffinger@gmx.de>.

Changed av_calloc to av_mallocz, added overflow checks.

44deb9f68d mfxdec: Separate mxf_essence_container_uls for audio and video. 
It is a really bad idea to assign a video codec id
when we have set codec_type to audio and vice versa.

775d3b4ab1 mxfdec: Speed up metadata and index parsing. 
Specifically, this means parsing as before until we run into essence.
At that point we seek to the footer and parse until EOF. After that we start
seeking backward to the previous partition and parse that until we run into
essence or the next partition. This procedure is repeated until we encounter
the last partition we parsed in the forward direction.

The end result of all this is that large essence containers are not needlessly
parsed. This speeds up parsing large files a lot.
