Support for VDPAU accelerated VP9 decoding was added with libvdpau-1.3.
Support for the same in ffmpeg is added with this patch. Profiles
related to VDPAU VP9 can be found in latest vdpau.h present in
libvdpau-1.3. DRC clips are not supported yet due to
http://trac.ffmpeg.org/ticket/8068
Add VP9 VDPAU to list of hwaccels and supported formats
Added file vdpau_vp9.c and Modified configure to add VDPAU VP9 support.
Mapped VP9 profiles to VDPAU VP9 profiles. Populated the codec specific
params that need to be passed to VDPAU.

Due to the recent addition of Vulkan support to AMF, we require more
recent headers that include the new structures, which have been
available since AMF 1.4.9 released in September 2018.
Fixes Ticket #8125

When compiling natively on an RPI where libomxil-bellagio-dev
was also installed, `check_headers OMX_Core.h` succeeded and
the -isystem compiler flag was never added to the build.
For non-native builds, the error message now mentions the
raspberrypi/firmware repository where the RPI specific

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.

The current code in libavfilter/af_sofalizer.c requires
mysofa_neighborhood_init_withstepdefine function, which only appeared
in libmysofa 0.7. Use this function in configure script to bail out
early if a too old libmysofa is found in the system instead of failing
at compile time.
Used a technique similar to lavc/tdsc.c for invoking the MJPEG decoder.
This commit adds support for:
- DNG tiles
- DNG tile huffman lossless JPEG decoding
- DNG 8-bpp ("packed" as dcraw calls it) decoding
- DNG color scaling [1]
- LinearizationTable tag
- BlackLevel tag

Many ffmpeg + rpi compilation guides on the internet recommend
using `./configure --enable-omx --enable-omx-rpi`. This fails
to find the IL OMX headers on device because the omx require_headers
check happens first before the add_cflags in omx_rpi.
A workaround is to use `./configure --enable-omx-rpi` only, since
omx_rpi already implies omx. But because many users expect to use
existing scripts and commands, we swap the order here so omx_rpi
special cases are applied first.
In the past this wasn't an issue because users noticed the OMX_Core.h
missing error and installed libomxil-bellagio-dev. But since
76c82843cc, the rpi specific headers from /opt/vc/include/IL
are required.

Since there was no space between '-include' and the path, MSYS2 doesn't

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.

Get rid of pr dependency and write the columns strictly
alphabetical without page size considerations (POSIX
specifies 66 lines as default).
Setting the page size via pr's -l option was considered,
but as there is issue #5680 which wants to avoid pr
mainly because it's not in busybox, we chose to replace
pr instead.
Before pr would attempt to write pages, thus if a page
boundary was reached, the output looked confusing as one
couldn't see there was a new page and the alphabetical
order was disrupted when scanning down one of the columns.
This change is based on a shell implementation submitted
before by Yejun.
Possible differences to the current version using pr:
1. pr implementations should truncate items to not overflow columns;
depending on how it's done not truncating shall be better IMHO.
2. pr implementations might balance columns differently;
we use minimum number of lines and might end up not
using all columns or might have lesser entries in the
last column(s)
3. we use spaces only for padding the columns; at least the GNU pr
version on my system also by default stuffs in tabs in addition
to a single space in between columns. I don't see that this
behaviour is demanded by POSIX, though I might be very well
overlooking things. Anyway for our use case I can't see a need
for having the additional tabs, or why it would be better compared
to padding with spaces only.
Fixes output for sizes with width < column width, too.
Fixes remaining part of ticket #5680

These functions are available in time.h (conditional on posix thread
safe functions) on mingw.
Previously, these functions weren't detected by configure, and
libavutil/time_internal.h provided replacements, even if time.h
actually contained definitions of them.
These mingw inline functions are currently defined as
"extern __inline __attribute__((__gnu_inline__))". In this case,
redefining a new static inline version of the same function with the
same name is tolerated.
