Conflicts:

Merged-by: Michael Niedermayer <michaelni@gmx.at>
The only parameters needed by the demuxers are the sample rate and sample
count, which can be trivially extracted manually, without resorting to
an avpriv function.
Currently, the API takes an external AVCodecContext, which is used only
for extradata and logging. This change will allow to it to work without
an AVCodecContext in the following commits.
This is a regression, previous code did not require
users to set the profile to use VDPAU.
In addition, ASP is a superset of SP, so there is not
even a good reason to require it.

* commit '26ab504ad8d2b23535c9a0ad43bf1fd0e6aa0893':
vdpau/h264: request MAIN rather than BASELINE VDPAU profile for CBP
Merged-by: Michael Niedermayer <michaelni@gmx.at>
The H.264 Constrained Baseline Profile (CBP) is a subset of both the
Main Profile and the Baseline Profile. In principles, a hardware
decoder that supports either of those can decode CBP content. As it
happens, Main is supported by all VDPAU drivers, and Baseline is not.
So favor map CBP to MP for now. Hopefully in the future libvdpau will
offer an explicit choice for CBP.

libfdk-aacdec: Enable Dynamic Range Control Metadata Support
Conflicts:
libavcodec/version.h
Merged-by: Michael Niedermayer <michaelni@gmx.at>
For streams which contain DRC metadata, the FDK decoder is able to
control rendering of the decoded output. The rendering parameters
are detailed in fdk_aac_dec_options [].
The default behavior is left up to the decoder.
Signed-off-by: Martin Storsjö <martin@martin.st>
The FDK decoder is capable of producing mono and stereo downmix from
multichannel streams. These streams may contain metadata that control
the downmix process. The decoder requires an Ancillary Buffer in order to
correctly apply downmix in streams containing downmix Metadata. The
decoder does not have an API interface to inform of the presence of
Metadata in the stream, and therefore the Ancillary Buffer is always
allocated whenever a downmix is requested.
When downmixing multichannel streams, the decoder requires the output
buffer in aacDecoder_DecodeFrame call to be of fixed size in order to
hold the actual number of channels contained in the stream. For example,
for a 5.1ch to stereo downmix, the decoder requires that the output buffer
is allocated for 6 channels, regardless of the fact that the output is in
fact two channels.
Due to this requirement, the output buffer is allocated for the maximum
output buffer size in case a downmix is requested (and also during
decoder init). When a downmix is requested, the buffer used for output
during init will also be used for the entire duration the decoder is open.
Otherwise, the initial decoder output buffer is freed and the decoder
decodes straight into the output AVFrame.
