Also use that to support mapping VAAPI to Beignet.

Behaves like the existing avgblur filter, except working on OpenCL
hardware frames. Takes exactly the same options.

This can remove units with types in or not in a given set from a stream.
For example, it can be used to remove all non-VCL NAL units from an H.264 or
H.265 stream.

Use it as the set of codec IDs supported by the trace_headers BSF.

Previously the bit pattern for the endianness test was declared as a
global, instead of a local, variable. This ensures that the pattern
appears unchanged in the object file and is not optimized out.

Fail if AMF is requested but unavailable, as we do for all
other external libraries that need to be explicitly enabled.

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.|
