Vincent Penquerc'h 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.

Vincent Penquerc'h 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).

Arun Raghavan 96972eb462 ac3parse: Add support for IEC 61937 alignment

code to collect all the frames needed to meet this requirement before
pushing out a buffer.

also change between packets, which would result in incorrect buffer

Arun Raghavan 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.

Mark Nauwelaerts 76b322a429 baseparse: enhancements for timestamp marked framed formats 
That is, as such formats allow subclass to extract position from frame,
it is possible to extract duration (if not otherwise provided)
from (near) last frame, and a seek can fairly accurately target the required
position.

Fixes #631389.

Sebastian Dröge 572366e179 flacparse: Don't parse the complete FLAC frames but only look for valid frame headers 
Thanks to Felipe Contreras for the suggestion. This is partially
based on his patches and makes flacparse more than 3.5 times faster.

Looking for valid frame headers is unlikely to give false positives
because every frame header is at least 9 bytes long, contains a
14 bit sync code and a 8 bit checksum over the first 8 bytes.

Fixes bug #631200.

Sebastian Dröge bfdc132ad0 flacparse: Really post tags only after the initial newsegment event 
The first newsegment event will be send by the first call to
gst_base_parse_push_buffer() if necessary, posting the tags

GstBaseParse::pre_push_buffer vfunc.

This reverts commit b5a3d60363.

Reverting this for now, since no one really seems to remember why this
property exists or what it could possibly be good for. It seems to have
been in the original mp3parse since the beginning of time and was back-
ported from there.

Seekability, like duration, etc is unlikely to change (frequently), and

Arun Raghavan f7e228edb0 baseparse: Don't emit bitrate tags too early 
We wait to parse a minimum number of frames (10, arbitrarily) before
emiting bitrate tags so that our early estimates are not wildly
inaccurate for streams that start with a silence. If the stream ends
before that, we just emit the tags anyway.

While it _would_ be nicer to be specify the threshold to start pushing
the tags in terms of duration, this would introduce more complexity than
this merits.

Sebastian Dröge 00b0444618 flacparse: Optionally check the overall frame checksums too before accepting a frame as valid 
This is optional because it's a quite expensive operation and it's very
unlikely that a non-frame is detected as frame after the header CRC check
and checking all bits for valid values. The overall frame checksums are
mainly useful to detect inconsistencies in the encoded payload.

Arun Raghavan 44878511b2 aacparse: Fix bitrate calculation 
This patch adds the get_frame_overhead() vfunc so that baseparse can

(it's not in the header as the code suggests).

Arun Raghavan 733669e076 audioparsers: Add bitrate calculation to baseparse 
This makes baseparse keep a running average of the stream bitrate, as
well as the minimum and maximum bitrates. Subclasses can override a
vfunc to make sure that per-frame overhead from the container is not
accounted for in the bitrate calculation.

We take care not to override the bitrate, minimum-bitrate, and
maximum-bitrate tags if they have been posted upstream. We also
rate-limit the emission of bitrate so that it is only triggered by a
change of >10 kbps.
