The reference frames are used in update_thread_context(), so modifying
them after finish_setup() is a race. The frame in question will be
released during the next decode call.

This allows these flags to be automatically enabled for clang,
when using MSVCRT headers.

This allows doing this redirection, if building with clang against
old enough MSVC headers that lack strtoll (2012 and older).

Avoid a warning for passing an unsigned value to abs(), some compilers
might optimize away abs().

The range field has been introduced in version 1.6.0

It should only be done for DEVICE_BUSY/IN_EXECUTION

Include the libmfx error code and its description

Other parameters, like the display size, should still be taken from the
codec context.

This will allow using this function for encoding as well, where the
input format is already the semi-packed version.

Currently it's memset to 0, which is YUV420P. It should be initialized
to none.

Do not hardcode NV12. This allows 10bit decoding with -hwaccel qsv.

This is required e.g. by HEVC.

The setpts filter does not signal to the rest of the filtergraph that
the stream is CFR. Just generate the timestamps manually instead.

According to the specification on the MSDN [1], 0 is valid for that
particular field, and it should be ignored in that case.

This reverts commit 0e0538ae.

The valgrind warning was a false positive due to OSX implementation of
printf (invoking a strnlen), while this code is actually fine, since the
format specifier %.*s guarantes that no more than buf_size bytes from
buf will be read.

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
(for DECLARE_ASM_CONST).

There are samples with invalid stsc that may work fine as is and
do not need extradata change. So ignore any out of range index, and
error out only when explode is set.
