829507b650 baseparse: allow increasing min_size for current frame parsing only 
Also check that subclass actually either directs to skip bytes or
increases expected frame size to avoid going nowhere in bogus
indefinite looping.

a6a982e8be audioparsers: baseparse: Be careful to not lose the event ref 
Don't unref the event if it hasn't been handled, because the caller
assumes it is still valid and might reuse it.

I ran into this problem when transcoding an AVI (with mp3 inside)
to gpp.

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 
We lose the reference to the buffer after gst_pad_push(), so the debug
print should happen before.

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.

emit tags or messages at this time.
