94daabf71f aacparse: Implement ::get_sink_caps vfunc to propagate downstream caps constraints upstream 2011-11-24 09:43:54 +01:00

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).

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.

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.

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.

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.
