46b004959b ffv1: Fixed size given to init_get_bits() in decoder.
init_get_bits() takes a number of bits and not a number of bytes as
its size argument.

ec6402b7c5 lavc: use designated initialisers for all codecs.
It's more readable and less prone to breakage.

0a6b1a9f21 Replace int_fast integer types with their sized standard posix counterparts.
The _fast integer types provide no realworld benefits, but may introduce
portability issues and are just plain ugly.

d36beb3f69 Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf.
None of these symbols should be accessed directly, so declare them as
hidden.

58b4e5407d Fix FFv1 decoder buffer releasing.
Previously it was releasing the buffer which was returned to the user,
which was resulting in a crash in case of direct rendering.
