c085f1a7e1 opus_parser: make ParseContext the first element in OpusParseContext
ff_parse_close expects priv_data to be the ParseContext directly and
thus doesn't work if it isn't at the beginning of OpusParseContext.

5b73ba9887 avcodec/mpeg12dec: Add FF_CODEC_CAP_SKIP_FRAME_FILL_PARAM
This decreases the amount of computations and memory needed for analysing mpeg1/2 streams

the properties update is moved from code that is skiped if skip_frame is set
to code that is not skiped so the change doesnt loose that

27038693bb avcodec/nvenc: Delay identification of underlying format of cuda frames
When input surfaces are cuda frames, we will not know what the actual
underlying format (nv12, p010, etc) is at surface allocation time.

On the other hand, we will know when the input frames are actually
registered and associated with a surface.

So, let's delay format discovery until registration time, which is
actually how we handle other frame properties, such as dimensions.

By itself, this change doesn't allow for transcoding of 10bit
content from cuvid, but it reduces the problem to the hardcoding of
the sw format in ffmpeg_cuvid.c

e856ac2373 avcodec/msrledec: implement vertical offset in 4-bit RLE
The delta escape (2) is supposed to work the same in 4-bit RLE as in
8-bit RLE.  This is documented in the MSDN Bitmap Compression page:
https://msdn.microsoft.com/en-us/library/windows/desktop/dd183383(v=vs.85).aspx

The unchecked modification of line is safe, since the loop condition
(line >= 0) will check it before any pixel data is written.
