Implemented as a variant of the hash muxer, reusing most functions,
and making use of the previously introduced array of hashes.

When ffmpeg was streaming, multiple clients were only supported by using a
multicast destination address. An alternative was to stream to a server which
re-distributes the content. This commit adds ZeroMQ as a protocol, which allows
multiple clients to connect to a single ffmpeg instance.

Added linux support for amf encoder through vulkan.

To use h.264(AMD VCE) encoder on linux amdgru-pro version 19.20+ and
amf-amdgpu-pro package(amdgru-pro contains, but does not install
automatically) are required.

This driver can be installed using amdgpu-pro-install script in
official amd driver archive.

Initialization of amf encoder occurs in this order:
1) trying to initialize through dx11(only windows)
2) trying to initialize through dx9(only windows)
3) trying to initialize through vulkan

Only Vulkan initialization available on linux.

This avoids using the CUDA SDK at all; instead, we provide a minimal
reimplementation of the basic functionality that lavfi actually uses.
It generates very similar code to what NVCC produces.

The header contains no implementation code derived from the SDK.
The function and type declarations are derived from the SDK only to the
extent required to build a compatible implementation. This is generally
accepted to qualify as fair use.

Because this option does not require the proprietary SDK, it does not require
the "--enable-nonfree" flag in configure.

Fixes #7671.

The latest generation video decoder on the Turing chips supports
decoding HEVC 4:4:4. This change adds AV_PIX_FMT_VDPAU as a valid format
for HEVC 4:4:4 8 bit.

Fixes #4711.

This will be needed by the eventual native AV1 decoder.

Fixes ticket #4519.

The metadata starting at 0xe00004 is encrypted
with the password "meta" but zlib does not
support decryption, so no kux metadata is read.

This work is sponsored by VideoLAN.

I forgot to add the version bump and changelog within the changes.

* Outputs ASS lines with basic coloring and font scaling for each
  given region.
* Sets the default style to the resolution of the subtitle plane
  (for example, 960x540 / 36pt font for profile A).
* Has options to:
  * Disable ruby text (which is coded as regions which have
    half-height text in libaribb24).
    Enabled by default as without positioning ruby text only
    confuses as it is usually coded in the beginning of the decoded
    subtitle line.
  * Set the working directory, in which libaribb24 will read
    configuration as well as into which it may save broadcast extra
    symbols as PNG.
    Unset by default.

The unconventional library check can be explained by the library's
current master branch being licensed as LGPLv3, but at the time of
writing the latest official release is still licensed under GPLv3.

Thus, one either has to wait for the following release, or enable
GPLv3.

Thanks Kostya for great help in reversing binary.

This is a cuda implementation of yadif, which gives us a way to
do deinterlacing when using the nvdec hwaccel. In that scenario
we don't have access to the nvidia deinterlacer.
