This can reduce latency and increase throughput, particularly on high
latency networks.

The avc3 sample entry type is useful for adaptive streaming. It permits
parameter sets to be written inline in the video stream.

By putting the call in a subshell, the problem of it spilling
cleanup-decision from a previous library to other libraries is avoided.
For example, it could have already cleaned up cuda_extralibs in a
previous library that depended on cuda. Then when it gets to avutil, it
will never pick up the dependency of avutil to cuda, which depends on
libdl, which in turn results in a missing -ldl extralib, resulting in
link failures in certain configurations.

This avoids having to use either "dumpbin -headers" to find out
the current architecture, or pass $ARCH from configure to deduce it.
When configuring with --disable-asm, ARCH is equal to "c", which doesn't
give any indication of what symbol prefix is to be used.

alloc_frame_buffer in ff_alloc_picture asserts that the linesize
of planes 1 and 2 are the same. If the pixfmt has a single uv
plane, like NV12, this won't be true.
So, let's only do this check if there are more than 2 planes.
We never hit this with previous hw formats because they don't set
linesize to meaningful values, but the cuda hw format sets the
values based on the underlying data layout.
After c2a8f0fcbe this can happen on normal edit lists starting on a B-frame.

The macros for ICC and MSVC correctly push and pop the diagnostic
state of the compiler when disabling deprecation warnings. The
ones for clang/gcc should do the same. Without this, if a blanket
deprecation warning is applied to the code base it'll be flipped
back on incorrectly with FF_ENABLE_DEPRECATION_WARNINGS.

Currently if you use the multiple_requests=1 option and try to
receive a chunked-encoded response, http_buf_read() will hang forever.
After this patch, EOF is emulated once a 0-byte final chunk is
received by setting a new flag. This flag is reset in ff_http_do_new_request(),
which is used to make additional requests on the open socket.

This is a partial fix - to fix videotoolbox fully (with multithreaded
hwaccel decoding), much more work would be required.
Before this change, an assertion failure would trigger:
$ ffmpeg -hwaccel videotoolbox -hwaccel_output_format videotoolbox_vld -i h264.ts -f null -y /dev/null
Assertion (frame->private_ref && frame->private_ref->size == sizeof(FrameDecodeData)) || !(avctx->codec->capabilities & (1 << 1)) failed at libavcodec/decode.c:620
