File libopenh264enc.c has been modified so that the encoder uses av_log()
to log messages (error, warning, info, etc.) instead of logging them
directly to stderr.  At the time the encoder is created, the current
libav log level is mapped to an equivalent libopenh264 log level.  This
log level, and a message logging function that invokes av_log() to
actually log messages, are then set on the encoder.

This contains further changes and simplifications by Michael Niedermayer
and Martin Storsjö.

It is not used outside of qsvdec.c anymore.

lavc expects MFX to still be in a usable state on close.

Even though libmfx might not need them anymore, avcodec might still
access the surfaces. So free them separately at the end.

Should fix some leaks on init failure.

This is useful for detecting QSV-enabled decoders.

It should be possible to pass hwaccel frames through lavfi.

The System V ABI on x86-64 specifies that the al register contains an upper
bound of the number of arguments passed in vector registers when calling
variadic functions, so we aren't allowed to clobber it.

checkasm_fail_func() is a variadic function so also zero al before calling it.

Tested functions are internally kept in a binary search tree for efficient
lookups. The downside of the current implementation is that the tree quickly
becomes unbalanced which causes an unneccessary amount of comparisons between
nodes. Improve this by changing the tree into a self-balancing left-leaning
red-black tree with a worst case lookup/insertion time complexity of O(log n).

Significantly reduces the recursion depth and makes the tests run around 10%
faster overall. The relative performance improvement compared to the existing
non-balanced tree will also most likely increase as more tests are added.

It appears vdpau drivers can return constrained baseline as unsupported,
even if libvdpau knows about the symbol, and the main profile is
supported.

Note that this slightly changes behavior: it sets AVMEDIA_TYPE_UNKNOWN
if the codec type is unknown. This should be ok.

This function can intrinsically not deal with codec profile fallback
(for H.264 Constrained Baseline especially), and was made redundant
by av_vdpau_bind_context().

Header does not contain the number of channels, but rather the encoder
version, so rename the variable, and read the additional byte.

AVBufferRef.data and AVPacket.data don't need to have the same value.
AVPacket could point anywhere into the buffer. Likewise, the sizes
don't need to be the same.

This works only for extradata sizes up to 128 bytes. Additionally, I
could never actually see it doing anything. The new code using
MMAL_BUFFER_HEADER_FLAG_CONFIG now takes care of this.

We can send mp4-style data directly. But for some reason, this requires
sending the extradata as buffer with MMAL_BUFFER_HEADER_FLAG_CONFIG
set. Reuse the infrastructure for sending AVPackets to do this.

Add an allowed parameter to -h and --help avconv option to print private
options from a codec, format, or filter, named with the provided input
value.

In case multiple classes are found (eg. mov demuxer and mov muxer, or
h264 decoder and h264 demuxer) print all options from all classes.
It is possible to select the type of class to print by adding it
before the name (eg. demuxer:mov and muxer:mov, or decoder:h264and
demuxer:h264).

Since the actual max length of the jitter buffer is restricted by
max_delay, this shouldn't harm the overall latency (assuming that
max_delay is set properly), while allowing packet reordering with
a larger number of packets (which may be required with high bitrate
video).
