Right now, if someone configures ffmpeg with for example --enable-nvenc they will
get an error message complaining about missing cuda.
This is very confusing and already has lead people into installing the CUDA SDK,
even though it's not what they need.

This will make it complain about ffnvcodec instead.

External headers are no longer welcome in the ffmpeg codebase because they
increase the maintenance burden. However, in the NVidia case the vanilla
headers need some modifications to be usable in ffmpeg therefore we still
provide them, but in a separate repository.

The external headers can be found at
https://git.videolan.org/?p=ffmpeg/nv-codec-headers.git

Fate-source is updated because of the deleted files, and dynlink_loader.h
license headers were updated with the standard FFmpeg headers.

The GCC generated import libraries don't work properly when being imported
by MSVC, resulting in missing symbols at runtime.

This reverts 5b5365fe and partially reverts changes from 98a9b1f0

These are supported by llvm-dlltool.

This reverts commit 67c72f08.

While the linker produced import libraries might work with MSVC in
simple test cases, they don't if e.g. linking to multiple GNU ld
produced import libraries at the same time. (They end up importing
functions from the wrong libraries.) The ones produced by dlltool
work fine though.

This issue was pointed out by Hendrik Leppkes.

This also adds an avpriv function to register devices in
libavformat

Based on an unfinished patch by atomnuker.

Skip a variable indirection and only redefine restrict if necessary.

This also moves the setting of the licensing string out of a block that
is skipped when quiet operation is requested.

Usage is:
./vaapi_transcode input_stream codec output_stream
For example:
- ./vaapi_transcode input.mp4 h264_vaapi output_h264.mp4
- ./vaapi_transcode input.mp4 vp8_vaapi output_vp8.ivf

Does not handle resolution changes on the input stream.

Currently the Windows CC_IDENT is ended with '\r\n'. "head -n1" will not
remove the '\r' and this is causing building error in Chromium.

This CL adds "tr -d '\r'" to remove '\r' in the CC_IDENT string. Since in
most cases '\r' only appears at the end of a string/line, this should
work in most cases.

See example:

printf "hello\r\nworld\r\n" | head -n1 | hd
00000000  68 65 6c 6c 6f 0d 0a                              |hello..|

printf "hello\r\nworld\r\n" | head -n1 | tr -d '\r' | hd
00000000  68 65 6c 6c 6f 0a                                 |hello.|

Fixes a regression since 6dfcbd80.

check_func_headers() defines a main() function, which clashes with a
redefinition done by said SDL header. Check for SDL_PollEvent using
SDL_events.h only instead, where the redefinition doesn't happen.

Fixes a regression since d03c39b4.

SDL2 uses SDLCALL to specify a calling convention. On OS/2, it's defined
to `_System' which is similar to `_cdecl' but does not prepend '_'.

After all, without a header, a function is used without `_System'. And
linker will try to `_func' but fail because the function is `func' not
`_func'.

This patch is taking care of https://trac.ffmpeg.org/ticket/6834.
It seems that one of the control operations that was available to get
the free decoders input slots was removed.

There is another control operation to retrieve the used slots. Given
that the input slot count is hardcoded to 4 in mpp at this point,
replacing the old control operation by the other one.

This was tested on Rockchip ROCK64.

Deprecate the entire library. Merged years ago to provide compatibility
with Libav, it remained unmaintained by the FFmpeg project and duplicated
functionality provided by libswresample.

In order to improve consistency and reduce attack surface, as well as to ease
burden on maintainers, it has been deprecated. Users of this library are asked
to migrate to libswresample, which, as well as providing more functionality,
is faster and has higher accuracy.

This removes the XP compatibility code, and switches entirely to SWR
locks, which are available starting at Windows Vista.

This removes CRITICAL_SECTION use, which allows us to add
PTHREAD_MUTEX_INITIALIZER, which will be useful later.

Windows XP is hereby not a supported build target anymore. It was
decided in a project vote that this is OK.
