It randomly causes failures with an error like:
"Failed to set value '-f' for option 'd': Error number -920332800 occurred"
(The error number is different every time.)

This matrix needs to be applied after all others have (currently only
display matrix from trak), but cannot be handled in movie box, since
streams are not allocated yet. So store it in main context, and apply
it when appropriate, that is after parsing the tkhd one.

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

Using the decode interrupt feature of ffmpeg may cause crashes by
accessing previously freed pointers in matroska_read_close.
To prevent this reset nb_elem to zero after freeing the elements,
because ffmpeg normally tests for nb_elem.

The code calls av_new_packet a few lines above and the allocated memory
has to be freed in case of an error.

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:

The unchecked modification of line is safe, since the loop condition
(line >= 0) will check it before any pixel data is written.
Fixes ticket #5153 (output now matches ImageMagick for the provided sample).

This fixes a heap-buffer-overflow in ff_er_frame_end when decoding mss2
with coded_width/coded_height larger than width/height.
