Mark Nauwelaerts 57babfca39 amrparse: properly check for sufficient available data prior to access 2011-01-28 12:16:58 +01:00
Mark Nauwelaerts 3ba3339993 baseparse: ensure non-empty candidate frames 2011-01-28 12:16:58 +01:00

Mark Nauwelaerts 16342223ee baseparse: properly track upstream timestamps 
... rather than with a delay.
 2011-01-28 12:16:58 +01:00
Mark Nauwelaerts b97e560f1a baseparse: need proper frame duration to obtain sensible frame bitrate 2011-01-28 12:16:58 +01:00
Mark Nauwelaerts 559b3ead93 baseparse: proper initial values for index tracking variables 2011-01-28 12:16:58 +01:00
Mark Nauwelaerts f3da619dd2 baseparse: arrange for consistent event handling 2011-01-28 12:16:58 +01:00
Mark Nauwelaerts 18b347296c baseparse: header style cleaning 2011-01-28 12:16:58 +01:00
Mark Nauwelaerts 2c872ad913 baseparse: provide some more initial frame metadata in parse_frame 
... and document accordingly.
 2011-01-28 12:16:57 +01:00
Mark Nauwelaerts 6a45c4f65e 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.
 2011-01-28 12:16:57 +01:00
Mark Nauwelaerts 1c89488c50 baseparse: introduce a baseparse frame to serve as context 
... and adjust subclass parsers accordingly
 2011-01-28 12:16:57 +01:00
Mark Nauwelaerts 400198b2cd baseparse: restrict duration scanning to pull mode and avoid extra set_caps call 2011-01-28 12:16:57 +01:00
Mark Nauwelaerts 3e9d5c4bf8 baseparse: update some documentation 
Also add some more debug.
 2011-01-28 12:16:57 +01:00
Mark Nauwelaerts 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.
 2011-01-28 12:16:57 +01:00
Mark Nauwelaerts 18b69e9320 baesparse: fix refactor regression in loop based parsing 2011-01-28 12:16:57 +01:00
Mark Nauwelaerts f4f7306e37 baseparse: pass all available data to subclass rather than minimum 
Also reduce some adapter calls and add a few debug statements.
 2011-01-28 12:16:57 +01:00
Mark Nauwelaerts e54e2a9616 baseparse: fix reverse playback handling 2011-01-28 12:16:56 +01:00
Mark Nauwelaerts 695c9599f4 baseparse: minor typo and debug statement cleanup 2011-01-28 12:16:56 +01:00
Mark Nauwelaerts fcd0f5cb7a baseparse: reduce locking 
... which is either already mute and/or implicitly handled by STREAM_LOCK.
 2011-01-28 12:16:56 +01:00
Mark Nauwelaerts 3da135ce02 baseparse: avoid loop in frame locating interpolation 2011-01-26 17:16:49 +01:00
Mark Nauwelaerts 289cd65abd flacparse: mind gst_buffer_unref not liking NULL 
Fixes #639950.

Thiago Santos 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.

Tim-Philipp Müller aba0899b19 dcaparse: fix sync word for 14-bit little endian coding 
Fix copy'n'paste bug that made us look for the raw little endian
sync word twice instead of looking for the 14-bit LE sync word
as well. Fixes parsing of such streams (see #636234 for sample file).
 2011-01-13 17:10:13 +00:00
Tim-Philipp Müller 095eaa1752 docs: minor baseparse docs/comment fixes 
Remove copy'n'paste leftovers.

Mark Nauwelaerts fa0dea3fdc dcaparse: add to documentation 2010-12-03 18:23:14 +01:00
Mark Nauwelaerts 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).
 2010-12-03 18:23:06 +01:00
Mark Nauwelaerts ce6d8b6d93 ac3parse: use proper EAC-3 caps 2010-12-01 15:29:55 +01:00

 2010-11-25 17:28:16 +01:00
Mark Nauwelaerts 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.
 2010-11-17 16:24:13 +01:00
Mark Nauwelaerts 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.

Mark Nauwelaerts 08cab00b8b baseparse: refactor frame scanning peformed by _loop 2010-11-17 15:36:38 +01:00

Mark Nauwelaerts 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.

Mark Nauwelaerts 61cf6f2ffa baseparse: reflow update_bitrate code 
... which makes local variables represent real state better, and avoids
triggering unneeded updates/actions.
 2010-10-29 14:11:44 +02:00
Mark Nauwelaerts 841e09e234 baseparse: add some debug statements 2010-10-29 14:11:42 +02:00

Tim-Philipp Müller d5a008b9ee audioparsers: add very basic dts/dca parser 
Still some issues, e.g. with seekable queries in totem, but also
processing already-chunked input (created with matroskademux ! gdppay).
