26feb26fc1 baseparse: increase keyframe awareness
... which is not particular relevant for audio parsing, but more so
in video cases.  In particular, auto-determine if dealing with video (caps).

68dca2e704 baseparse: use correct offset when adding index entry
... bearing in mind that BUFFER_OFFSET is media specific and may not
reflect the basic offset after having been parsed.

9b6439a36c 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.

f82f330537 baseparse: minor fixes and enhancements
Arrange for upstream as well as downstream flushing when seeking.
Also determine upstream size as well as seekability.  Adjust some comments
to reality and employ debug statement in proper order.

716e430fd5 Revert "baseparse: add skip property"
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.

2d699010e9 baseparse: Fix debug output

4dff7c81d6 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.

2978216db1 baseparse: Allow chaining of subclass event handlers

90753ceb5e 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.

af00e59528 baseparse: Send NEWSEGMENT event with correct start and position

of starttime) always take the buffer starttime.
