7ba1b6e4d7 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.

03164ad8ab 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.

1b8a96e999 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.

eb73b3e933 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.

e85f8c8ab6 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.

Fixes bug #614016.

102ee0cf41 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.

1bc8301c79 baseparse: fix/enhance DISCONT marking
In particular, consider DISCONT == !sync, and allow subclass to query
sync state, as it may want to perform additional checks depending
on whether sync was achieved earlier on.
Also arrange for subclass to query whether leftover data is being drained.

48b4912c2e baseparse: add timestamp handling, and default conversion
In particular, (optionally) provide baseparse with a notion of frames per second
(and therefore also frame duration) and have it track frame and byte counts.
This way, subclass can provide baseparse with fps and have it provide default
buffer time metadata and conversions, though subclass can still install
callbacks to handle such itself.

14a3a9f42a baseparse: use_fixed_caps for src pad
After all, stream is as-is, and there is little molding to downstream's
taste that can be done.  If subclass can and wants to do so, it can
still override as such.

Also handle the case gracefully where the subclass decides to drop
