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 some differences between runs of the ffserver tests
(in my local tree 2 runs gave the same result with this but i had other
changes too)

This fixes a segmentation fault caused by calling memcpy with NULL as
second argument in handle_p_frame_apng.

Fixes null pointer dereference
Testcase is simply a ffmpeg instance sending a stream to ffserver while another ffmpeg reads from it
This reverts commit 6f0a1710d7.
Since this is a C11 feature, it requires -std=c11.

give very bad quality for soxr resampler.
linear_interp is intended for using linear interpolation
between filter bank so quality will be better.
i guess this is misunderstood as 'do not use filter bank,
but directly interpolate linearly between samples'.
