440d7034f0 flacparse: perform additional frame crc check if applicable
... such as a frame header parsing throwing some suspicious warnings.
So we can be a bit more convinced we determine the right frame end.

58816039c2 flacparse: avoid indefinite extended search for frame end if possible
... which is particularly useful if locked on to the wrong frame start
and/or corrupt frame being crc checked.

93ac6fb47e ac3parse: let bsid 9 and 10 through
Files with 9 and 10 happen, and seem to comply with the <= 8
format, so let them through.
The spec says nothing about 9 and 10.

16a4c596eb aacparse: parse LOAS variant
The LOAS variant seems to have three different subvariants itself,
only one of them is implemented as my two samples happen to be
using that one.
The sample rate is not always reported correctly, as the "main"
sample rate is apparently sometimes half what it should be (both
of my samples report 24000 Hz there), and there are two other
parts of the subvariant with different sampling rates. One of them
is parsed, but not the other, as it's located after some other
large amount of variable data that needs parsing first, and there
seems to be a LOT of it, which is useless for our needs here.
This ends up being rather inconsequential, as ffdec_aac_latm,
which is the only decoder that can decode such streams, does not
need the sample rate on the caps anyway.

Otherwise we might trigger at some point within the file, but the
check is only making sense for the second block.

011c33e91e flacparse: detect when a file lies about fixed block size
If the sample/block number happens to be the same as the block
size, we assume variable block size, and thus counters in samples
in the headers. This can only get us a false positive for a block
size of 1, which is invalid. We can get false negatives more
often though (eg, if not starting at the start of the stream),
but then that's already GIGO.

14a9d1d66e flacparse: fix last frame timestamp in fixed block size mode
The last block may have a different block size, so we should not
use it to scale or we'll end up with a wrong timestamp.
See comment and quote from the FLAC format documentation in the code.

Fixes looped playback of FLAC files (via about-to-finish).

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

into time itself when needed.
