dd140c7b4d mpegaudioparse: initial version
... adequately equivalent to mp3parse, so lets boldly set it
to higher rank.

f218b984cc baseparse: use _set_duration to configure duration update interval
... as it logically belongs there as one or the other; either subclass
can provide a duration, or an estimate must be made (reguarly updated).

0198d6320b baseparse: remove is_seekable vmethod and use a set_seek instead
Seekability, like duration, etc is unlikely to change (frequently), and
the default assumption covers most cases, so let subclass set when needed.
At the same time, allow subclass to indicate if it has seek-metadata (table)
available, and possibly have it provide an average bitrate.

3448e83c73 baseparse: Allow chaining of subclass event handlers
This allows the child class to chain its event handler with
GstBaseParse, so that subclasses don't have to duplicate all the default
event handling logic.

a459494097 baseparse: fix seek handling
Allow a few more seek event type combinations, and really use the result
of gst_segment_set_seek to perform the seek.  Also add some debug.

6bd1be78bf check: Don't re-declare 'GList *buffers' in the tests
It's an external which lives in gstcheck.c. Redeclaring it makes some
compilers/architectures think the 'buffers' in the individual tests are
a different symbol... and therefore we end up comparing holodecks with
oranges.

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.

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.

7b10c2afce flacparse: Check the CRC-8 of the headers before accepting a frame as valid
This makes false-positives during seeking much less likely and detection of
them much faster.

017bb65d06 baseparse: Send NEWSEGMENT event with correct start and position
Instead of taking the last stop (which could be buffer endtime instead
of starttime) always take the buffer starttime.

7184fe911d flacparse: Fix buffer refcount issue
When called from the GST_FLAC_PARSE_STATE_HEADERS case,
gst_flac_parse_hand_headers() does a gst_buffer_set_caps() on a buffer
with refcount > 1. This change handles this case by making the buffer
metadata_Writable.

44878511b2 aacparse: Fix bitrate calculation
This patch adds the get_frame_overhead() vfunc so that baseparse can
accurately calculate the min/avg/max bitrates for aacparse.

Note: The bitrate was being incorrectly calculated for ADTS streams
(it's not in the header as the code suggests).

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.
