Here the rough draft, I'm not sure if is worthy adding avoptions or not
at this stage.
In general the common set of options are seed and digest_length so I'm
keeping them separated.
Another open question is if it is worthy making init idempotent (so you
can issue as many times you want and it wil

The patch also increases an array size - why?

This patch and Patch 12, 13 and 14 are dropped. The 3 patches set I just

It is not posible to call get_buffer during frame-mt codec
initialization. Libavformat might pass huge amounts of data as
extradata after parsing broken files. The 'extradata' for the fuzzed

multiple slices.

Can be used to set multiple key/value pairs from a string.

This is similar to av_set_options_string() but can be used for cases
where av_set_string3() is not appropriate, e.g. child classes.
This simplifies adding a key/value pair list in a string to an
AVDictionary, which could then be passed
