Mark Nauwelaerts c38fbf8879 baseparse: refactor passthrough into format flags 
Also add a format flag to signal baseparse that subclass/format can provide
(parsed) timestamp rather than an estimated one.  In particular, such "strong"
timestamp then allows to e.g. determine duration.

Mark Nauwelaerts 75bf0cfa32 baseparse: introduce a baseparse frame to serve as context

Mark Nauwelaerts efe6f065d6 baseparse: update some documentation 
Also add some more debug.
 2011-04-08 15:44:54 +01:00
Mark Nauwelaerts e567d1776c 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.

Mark Nauwelaerts 3cf81d066f baseparse: pass all available data to subclass rather than minimum 
Also reduce some adapter calls and add a few debug statements.

Thiago Santos a3e55038ac 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.

Mark Nauwelaerts 4dc486ddc5 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).

Mark Nauwelaerts 4230c0b2e1 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.
 2011-04-08 15:44:53 +01:00
Mark Nauwelaerts 3faccbd29f 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.

Mark Nauwelaerts 6d3447c6ec 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.

Tim-Philipp Müller a4f5db7088 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.

Arun Raghavan c56f223da7 baseparse: Fix debug output 
We lose the reference to the buffer after gst_pad_push(), so the debug
print should happen before.

Mark Nauwelaerts 668ad3836a baseparse: use _set_duration to configure duration update interval

Mark Nauwelaerts 60a8533d48 baseparse: post duration message if average bitrates is updated 2011-04-08 15:44:51 +01:00
Mark Nauwelaerts 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.

Mark Nauwelaerts 4b0f92db79 baseparse: add another hook for subclass prior to pushing buffer

emit tags or messages at this time.
