Adds the new av_hwframe_map() function, which allows mapping between
hardware frames and normal memory, along with internal support for
implementing it.
Also adds av_hwframe_ctx_create_derived(), for creating a hardware

another by some hardware-specific means.

lavc: export the timestamps when decoding in AVFrame.pts
Merged-by: Hendrik Leppkes <h.leppkes@gmail.com>
This way, Doxygen is happier as aliases are now grouped together, and
it never handled #define's in an enum well in the first place.
Y400A already exists as an enum assignment.
Including this header in a C++11 program (inside extern "C") will
throw an error because it looks like a user-defined literal. Add a
space between the two tokens to avoid the problem.
memalign() is not guranteed to be compatible with free() or realloc()
and for platforms in this category we have --enable-memalign-hack
(which should be enabled automatically if such system is detected)
Trying to somehow half support systems that can free() memalign memory
but not reallocate it seems not worth the amount of work needed to
keep 2 then incompatible allocation systems and ensure their
seperation. That is unless this would affect a major platform
on which we want to avoid the memalign hack code
The warnings also cause wasted time and effort as people try
to maintain a separation that does not exist currently.

If no string argument is supplied when av_hwdevice_ctx_create() is
called to create a VAAPI device, we currently only try the default
X11 display (that is, $DISPLAY) to find a device, and will therefore
fail in the absence of an X server to connect to. Change the logic
to also look for a device via the first DRM render node (that is,
"/dev/dri/renderD128"), which is probably the right thing to use in
most simple configurations which only have one DRM device.
A non-existent av_buffer_pool_can_uninit() function is mentioned instead
of av_buffer_pool_uninit(). Also, this function is to be called by the
caller, not the pool itself.
In such a case behave as if the buffer was not reallocatable -- allocate a
new one and copy the data (preserving just the part described by the
reference passed to av_buffer_realloc).

AV_WN64 is meant for unaligned data, but the existing av_alias* unions
(without a definition for the av_alias attribute - we don't have one
for MSVC) indicate to the compiler that they would have sufficient
alignment for normal access, i.e. the compiler is free to assume
8 byte alignment.
On ARM, this makes sure that AV_WN64 (or two consecutive AV_WN32) is
done with two str instructions instead of one strd.

This avoids issues with expanding the argument multiple times,
and makes sure that it is of the right type for the following shifts.
Even if the caller of a macro could be expected not to pass parameters
that have side effects if expanded multiple times, these fallback
codepaths are rarely, if ever, tested, so it is expected that such
issues can arise.
Thefore, for safety, make sure the fallback codepaths only expand
the arguments once.

Clang normally disguises as GCC (defining __GNUC__), and thus get
all the normal GCC specific attributes.
Clang can also work as a drop-in replacement for MSVC, and in these
cases, it doesn't define __GNUC__, but defines _MSC_VER instead.
Even in these setups, it still supports the GCC style attributes,
thus use them, especially where there isn't any MSVC specific
version, or where the MSVC specific version doesn't work on clang

No longer make a dummy device configuration to query. Instead, just
return everything we recognise from the whole format list. Also
change the device setup code to query that list only, rather than
intersecting it with the constraint output.
This makes hwupload more usable on mesa/gallium where the video
processor only declares support for RGB formats, making it unable to
deal with YUV formats before this patch. It might introduce some
different trickier failures in the internal upload/download code
because the set of allowed formats there has changed, though I didn't
find any obvious regressions with i965.
Currently it's exported as AVFrame.pkt_pts, which is also the only use
for that field. The reason it is done like this is that lavc used to
export various codec-specific "timing" information in AVFrame.pts, which
is not done anymore.
Since it is confusing to the callers to have a separate field which is
used only for decoder timestamps and nothing else, deprecate pkt_pts and
use just AVFrame.pts everywhere.

This is ~2x faster for y not an integer on Haswell+GCC, and should
generally be faster due to the fact that anyway powf essentially does
this under the hood. Made an inline function in lavu/internal.h for this
purpose.
Note that there are some accuracy differences, that should generally be
negligible. In particular, FATE still passes on this platform.
Results in ~ 7% speedup in aac encoding with -march=native, Haswell+GCC.
before:
ffmpeg -i sin.flac -acodec aac -y sin_new.aac 6.05s user 0.06s system 104% cpu 5.821 total
after:
ffmpeg -i sin.flac -acodec aac -y sin_new.aac 5.67s user 0.03s system 105% cpu 5.416 total
This is also faster than an alternative approach that pulls in powf, gets rid of
the crufty NaN checks and other special cases, exploits knowledge about the intervals, etc.
This of course does not exclude smarter approaches; just suggests that
there would need to be significant work on this front of lower utility than
searches for hotspots elsewhere.
