Do this by switching from the dynamic buffer API to the AVBPrint API;
the former has no defined way to check for errors.
This also avoids allocating an AVIOContext.

This patch set adds support for reading/writing the Matroska
BlockAdditionMapping
elements, as well as for reading/writing dvcC/dvvC blocks in Matroska.
Created utility functions to read/write Dolby Vision boxes for ISOM.
This was done to avoid duplicating the code, as the Matroska blocks and MOV
Both parse/write implementations are based on mov/movenc.
This only adds support for the "Dolby Vision configuration box".
Other configuration boxes, such as
"Dolby Vision enhancement layer configuration box" are not supported.
The new functions will be used to implement parsing/writing the DOVI
Adds handling of dvcC/dvvC block addition mappings.
The parsing creates AVDOVIDecoderConfigurationRecord side data.
The configuration block is written when muxing into Matroska,
if DOVI side data is present for the track.
Most of the Matroska element parsing is based on Plex's FFmpeg source code.
To avoid duplicating code. The implementation in dovi_isom is identical.

Notes:
The IMF demuxer accepts as input an IMF CPL. The assets referenced by the
CPL can be
contained in multiple deliveries, each defined by an ASSETMAP file:
ffmpeg -assetmaps ,,... -i
If -asset

Up until now, the packets have been read in blocks of at most
eight bytes at a time; these blocks have then been decrypted
and then copied into a buffer on the stack (that was double
the size needed...). From there they have been copied to a packet.
This commit changes this: The data is read in on
We use ECB, not CBC mode here, so one does not need to reinitialize
the context; for the same reason, one can also just let av_tea_crypt()
loop over the blocks, avoiding a loop here.

Don't use different src and dst in av_tea_crypt(); use in-place
modifications instead. Also let av_tea_crypt() encrypt all three
blocks in one call.
