With compilers that do not support proper dead code elimination, like
Sun C 5.12, linking fails due to missing references to unavailable,
but also unused, symbols.

The code needs only a few definitions from cuda.h, so define them
directly when CUDA is not enabled. CUDA is still required for accepting
HW frames as input.
Based on the code by Timo Rothenpieler <timo@rothenpieler.org>.
Group them in a subsection of the external library section. That should
make them easier to find and understand how they fit in the scheme of
things.
Also, rewrite the description text in a similar way as in the previous
commit.
Add a more accurate description of what the switches actually do (i.e.
allow using the given library, not enabling the corresponding
codecs etc.).
Replace the library descriptions, in many cases boilerplate text without
useful information, with a short summary of what the library does.

svq3: drop the build dependency on the h264 decoder
Merged-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>
This uses a new MMAL feature, which limits the number of extra frames
that can be buffered within the decoder. VIDEO_MAX_NUM_CALLBACKS can
be defined as positive or negative number. Positive numbers are
absolute, and can lead to deadlocks if the user underestimates the
number of required buffers. Negative numbers specify the number of extra
buffers, e.g. -1 means no extra buffer, (-1-N) means N extra buffers.
Set a gratuitous default of -11 (N=10). This is much lower than the
firmware default, which appears to be 96.
This is backwards compatible, but needs a symbol only present in newer
firmware headers. (It's an enum item, so it requires a check in
configure.)

Register mmaldec as mpeg2 decoder. Supporting mpeg2 in mmaldec is just a
matter of setting the correct MMAL_ENCODING on the input port. To ease the
addition of further supported mmal codecs a macro is introduced to generate
the decoder and decoder class structs.

build: Add component for the SRTP common code
Merged-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>
The raspberry pi uses the alternative API/ABI for OMX; this makes
such builds incompatible with all the normal OpenMAX implementations.
Since this can't easily be detected at configure time (one can
build for raspberry pi's OMX just fine using the generic, pristine
Khronos OpenMAX IL headers, no need for their own extensions),
require a separate configure switch for it instead.
The broadcom host library can't be unloaded once loaded and started;
the deinit function that it provides is a no-op, and after started,
it has got background threads running, so dlclosing it makes it
crash.

This is added in 10.11, so we add a #define when building against older SDKs.
The decoder actually supports 7.1-channel eac3, but since the parser only
reports 6 channels, we end up decoding the 5.1 downmix (same as the internal
decoder) for now.
Previously, with JACK installed, the configure script would enable the
JACK indev; this broke on OS X due to an incomplete pthreads
implementation. Add some simple macros to map libdispatch to pthreads
on OS X.

The relocation hack broke debugging on mingw-w64 when using gdb. This
makes the reloc hack dependent on --disable-debug so it's still enabled
for release builds.
This is simply an immediate fix for the issue of broken debugging, we
should probably still look at the possibility of reverting it outright
if it proves to be more trouble than it's worth. For now keeping it
enabled for release builds is a reasonable trade off.

The intrax8 decoding process does not imply any kind of error
resilience, and the only call present is more related to how mpegvideo

Therefore have the parent decoders carry out er when actually needed.

The pkg-config file contains all opencv libraries, not only the

This change makes it possible to use the libopencv-imgproc-dev Debian

In particular one doesn't need to install the parts of opencv that

Fixes build of lavd/jack on linux if dispatch happens to be available on
this platform. dispatch, as well as its dependencies kqueue and pwq are
generally not installed / distribued on linux systems. If it happens to
be the case, you want to explicitely link against the libraries (using
-ldispatch) as opposed to darwin where it is part of the standard
library and -ldispatch doesn't work.

configure: Use `require` for the non-component options
Merged-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>
lavfi has been considered to be stable for a while now, so it is enabled
in most configurations. Supporting avplay without lavfi requires a lot
of nontrivial ifdef mess for no good reason.
4.9 was released precisely nine years after the first GCC version with
autovectorizer (4.0) and six years after the first GCC version with
`-ftree-vectorize` default to enabled on `-O3` (4.3). We've given GCC
enough time to fix those bugs.
FATE passes here on a x86-64 machine with both GCC 4.9.2 and 5.3.1.
Some optimization hotspots benefit greatly from this change, especially
those without handwritten assembly. For instance, the main function in
vf_phase is now 1.6x faster (1.2x overall) on my machine.
Or when building in-tree.
Also don't try to remove src on distclean in these cases.

The configure detection is bumped to X265_BUILD >= 68,
since API version 68 corresponds with the x265 1.8
release tarball. The warnings inside x265 about
12-bit being experimental were removed prior to API
version 72 a short time later. At this time of
writing, X265_BUILD is at version 80.
12-bit support in the HEVC standard was approved in
October 2014 as part of HEVC Version 2 and published
in January 2015:
