avcodec/videotoolbox: allow not setting the kCVPixelBufferPixelFormatTypeKey
...
If AVVideotoolboxContext.cv_pix_fmt_type is set to 0, don't set the
kCVPixelBufferPixelFormatTypeKey value on the VT decoder.
This makes VT output its native format, which can be much faster on
some hardware iterations (if the native format does not match with
the requested format, it will be converted, which is slow).
The default is still forcing nv12.

avformat: fix AVStream private fields marker
...
Public fields were added after the private fields (negating the entire
point of this). New private fields go into AVStreamInternal anyway.
The new marker was set by guessing which fields are supposed to be
private and wshich not. recommended_encoder_configuration is accessed by
ffserver_config.c directly, and is supposed to use the public API.
ffmpeg.c accesses AVStream.cur_dts, even though it's a private field,
but that seems to be an older error.

avcodec, avutil, avformat: remove AVOption requirement for some fields
...
Allow all struct fields to be accessed directly, as long as they're
public.
Before this change, many fields were "public", but could be accessed via
AVOption only. This meant they were effectively not public, but were
present for documentation purposes, which was incredibly confusing at
best.
