It is supposed to be set by decoders only.

The only thing the demuxer needs is the sample rate to set the timebase,
which can be simply read with AV_RB32.

This is required by the new API.

The callers should now set the stream timebase, not the codec one.

This silences a warning with gcc.

It was wrongly left unchanged when the version field had been
introduced. (c94e2e85)

This instruction is deprecated on ARMv8, and it is serializing on
some ARMv7 cores as well [1].

This fixes a segmentation fault because request_frame in fifo.c assumes
that the call to ff_request_frame will populate fifo->root.next.
Before, it was possible for request_frame in af_compand to not do this,
resulting in a null pointer access. Now, request_frame in af_compand
always will return at least one frame or an error, as per the API
specifications in avfilter.h for request_frame.

For implicit signaling cases (as possible for Spectral Band Replication
and Parametric Stereo Tools), the decoder must decode the first frame to
correctly identify the stream configuration (as called from
avformat_find_stream_info). The mechanism for this is built-in and only
requires adding CODEC_CAP_CHANNEL_CONF to the libfdk-aacdec AVCodec
struct.

librtmp can keep pointers to this string internally, and may
use them at shutdown as well.

All other files containing purely inline assembly are treated the same way.

This avoids a link failure with MMX disabled as the init functions
are referenced unconditionally.

This avoids a link failure with MMX disabled as now code and
initialization are compiled under the same condition.

The default error concealment method if none is set via
aacDecoder_SetParam(AAC_CONCEAL_METHOD) is set in
CConcealment_InitCommonData within the fdk-aac library
and is set to Energy Interpolation. This method requires one frame
delay to the output. To reduce the default decoder output delay and
avoid missing the last frame in file based decoding, use Noise
Substitution as the default concealment method.
