* avformat/hashenc: fix incorrect use of av_mallocz_array()Moritz Barsnick2019-09-23
| | | | | | | Fixes CID 1453867, CID 1453866, CID 1453865. Signed-off-by: Moritz Barsnick <barsnick@gmx.net> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
* avformat/hashenc: add streamhash muxerMoritz Barsnick2019-09-20
| | | | | | | | | Implemented as a variant of the hash muxer, reusing most functions, and making use of the previously introduced array of hashes.

* avformat/hashenc: use an array of hashesMoritz Barsnick2019-09-20
| | | | | | | | | | | | | | | | | Only the first element of the array is used currently, the other elements are in preparation for a new muxer calculating multiple hashes. Also move alloc/init code from the write_header() functions to dedicated init() functions, and the cleanup code from the write_trailer() functions to dedicated deinit() functions. hash_free() and framehash_free() turn out to be identical here, but will differ in the subsequent commit, so they are not consolidated.

* avformat/hashenc: rearrange options definitionMoritz Barsnick2019-09-20
| | | | | | | | | | Only the frame* muxers support the format_version option. Use macros to ease the proliferation of identical options to coming muxers as well.
