f07492e7fb avcodec/videotoolbox: set kCVPixelBufferIOSurfaceOpenGLTextureCompatibilityKey 
Makes sure the output can be mapped as OpenGL texture.
This is what at least video players normally want.

ade7c1a232 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.

227f6e1e8d 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.

554bc4eea8 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.
