d17d13219c ac3parse: use bsid 9 and 10 to control sample rate
See http://matroska.org/technical/specs/codecid/index.html

The spec is silent about this though...

f3fc3e1f69 aacparse: only require two frames in a row when we do not have sync
This avoids a single bit error dropping two frames unnecessarily.
The two consecutive frames check is still required when we don't
have sync.

6ac7ad8a2c flacparse: fix off by one in frame size check
Yes, I was tracking another bug and the small test file I generated
to test with improbably just happened to trigger this, with a second
and last frame of 1615 bytes.

89564fcb69 ac3parse: Support switching alignment on-the-fly
This allows switching of alignment for E-AC3 streams at run-time. This
is requested by downstream elements via a custom event.

96972eb462 ac3parse: Add support for IEC 61937 alignment
When pushing out buffers over S/PDIF or HDMI, IEC 61937 payloading
requires each buffer to contain 6 blocks from each substream. This adds
code to collect all the frames needed to meet this requirement before
pushing out a buffer.

fd38772d3e ac3parse: fix buffer duration on blocks-per-frame change
The gst_base_parse_set_frame_rate call was predicated on a change to
sample rate, duration or profile. However, the block count per frame can
also change between packets, which would result in incorrect buffer
durations.

a53540346a flacparse: tell baseparse the duration in samples for better accuracy
Tell GstBaseParse the duration in samples instead of time, so that
a duration query in DEFAULT format will return the correct number
of samples without rounding errors. Baseparse will convert this
into time itself when needed.

e0cadab5c2 flacparse: don't error out on invalid minimum_blocksize value in streaminfo header
We don't use it, so may just as well accept an invalid value
of 0 here, which is likely inconsequential anyway.

f3f44f81c3 baseparse: tune QUERY_SEEKING response
Even if we currently do not have a duration yet, assume seekable if
it looks like we'll likely be able to determine it later on
(which coincides with needed information to perform seeking).

7f4a61b56c mpegaudioparse: Post CBR bitrate as nominal bitrate
Even if VBR headers are missing, we can't guarantee that a stream is in
fact a CBR stream, so it's safer to let baseparse calculate the average
bitrate rather than assume a CBR stream. However, in order to make
/some/ metadata available before the requisite number of frames have
been parsed, this posts the bitrate from the non-VBR headers as the
nominal bitrate.
