[FFmpeg-devel] [PATCH 00/11] CRC32 support for Matroska muxer

[James Almer]

This patchsets implements the feature requested on ticket #4347.
The first three patches are preparation work. The first one isn't
strictly related to the implementation, but comes in handy
nonetheless.

Patches 4 to 11 can be squashed into a single commit before pushing
if that's prefered, but for review purposes i split things as one
patch per Level 1 element being adapted to write a CRC32 element.

Fate tests are updated as needed.

James Almer (11):
  avformat/matroskaenc: don't reserve space for stream duration tags if
    the output is not seekable

    the output is seekable
