This is needed because of 32bit float formats (which are difficult to
store in 16bits)

This also fixes undefined behavior found by fate

And set it for MJPEG.

This adds common code to query driver support and set appropriate
address/size information for each slice.  It only supports rectangular
slices for now, since that is the most common use-case.

Fixes memleaks.

This test ensures that you are able to send N number of slice NALUs in slice threaded mode to be decoded simultaneously

This error isn't particularly helpful as checking for mixed IDR/non-IDR
NALUs would need to be done at a higher level to actually be accurate.
Removing the error allows an API user to send individual slice NALUs
(i.e. incomplete frames) so they can take advantage of slice
threading. The ticket which this error was added for (#4408) no
longer segfaults after removing this error (as the bug was likely
fixed more properly elsewhere).

Libx264 uses strtok which is not thread safe. Strtok is used in
x264_param_default_preset in param_apply_tune in x264/common/base.c.
Therefore the flag must be removed.

x264 fixed the issue, once the fix is pushed to stable, an #if can be added
to re-enable the flag based on X264_BUILD number.

Fixes ticket #7446.

Revert "avcodec/decode: copy the output parameters from the last bsf in the chain back to the AVCodecContext"

This reverts commit f631c328.

The avcodec_parameters_to_context() call was freeing and reallocating
AVCodecContext->extradata, essentially taking ownership of it, which according
to the doxy is user owned. This is an API break and has produced crashes in
some library users like Firefox[1].

Revert until a better solution is found to internally propagate the filtered
extradata back into the decoder context, or a decision is made to change the
API.

This has no visible effects but I happened to run under the cuda
memcheck tool and it called it out as an error.

Several SRT options are missing. Since pkg_config requires libsrt v1.3.0 and above, it should be able to support options added in libsrt v1.3.0 and below.
This commit adds 8 SRT options.
sndbuf, rcvbuf, lossmaxttl, minversion, streamid, smoother, messageapi and transtype
The keys of option are equivalent to stransmit.

Allows arrangement of multiple windows such as:
ffmpeg -re -f lavfi -i mandelbrot -f sdl -window_x 1 -window_y 1 mandelbrot -vf waveform,format=yuv420p -f sdl -window_x 641 -window_y 1 waveform -vf vectorscope,format=yuv420p -f sdl -window_x 1 -window_y 481 vectorscop

Some changes by Marton Balint:
- allow negative position (partially or fully out-of-screen positions seem to
  be sanitized automatically by SDL (or my WM?), so no special handling is
  needed)
- only show window after the position is set
- do not use resizable and borderless flags at the same time, that caused
  issues in ffplay
- add docs
