[ffmpeg] Request YUVJ420P format explicitly
...
Requesting YUV420P can cause crashes with some versions of FFmpeg.

[ffmpeg] Add support for YUV444P pixel format in FFmpeg
...
We also prefer YUV444 format when the decoder supports it.

Do not create extra threads when decoding small videos with FFmpeg
...
Instead we use our current decoding's taskqueue.

Add support for libavcodec 57
...
At this point only the original FFmpeg project is supported.

Reduce threads used in FFmpeg video decoder
...
FFmpeg PDM currently uses as many cores (virtual or otherwise) as available *per* decoder. This means on a typical quad-core machine (for example), that's 8 threads per video.
This reduces the number of threads FFmpeg uses using the same logic as what is used by libvpx to ensure that we won't get a regression due to excessive memory/thread use.

Have specialized AVCodecContext initialization
...
A common initialization procedure is too restrictive, and we end up setting up audio configuration for video decoding and vice-versa.

Let FFmpeg manage its own memory allocation
...
The API to override memory allocation was deprecated years ago and was completely removed in libavcodec 57.

Fix VP9 decoding with recent version of libav.

Parse raw data to identify single frames before decoding
...
A VP9 or VP9 packet may contains alternate frames. They need to be fed separately to the FFmpeg decoder.

Properly assign the decoded sample duration
...
We default to the previous logic if for some unlikely condition we couldn't find the frame's duration (using the last input frame's duration).

Properly set the keyframe flag
...
We were incorrectly setting the keyframe flag of the last input sample rather than of the decoded one.

Use LibAV/FFmpeg logic to detect invalid pts
...
The logic was extracted from LibAV cmdutils.c. FFmpeg provides an API for that (av_frame_get_best_effort_timestamp()) unfortunately this isn't provided by LibAV.
So copy the logic instead in order to keep compatibility with the two forks.

Revert "Use demuxed dimensions to determine picture size and offset"

Causes build bustage. Also doesn't apply to H.264 video (which is currently our only use for FFmpeg).
