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.

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 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.

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).

In particular, also set src caps whenever changes in stream warrant doing so.

Sebastian Dröge 812075dc5d flacparse: Simplify frame header parsing by using lookup tables 
Based on a patch by Felipe Contreras.

See bug #631200.
 2010-10-07 23:38:26 +02:00
Sebastian Dröge 64407ca94b flacparse: Don't parse the complete FLAC frames but only look for valid frame headers 
Thanks to Felipe Contreras for the suggestion. This is partially
based on his patches and makes flacparse more than 3.5 times faster.

Looking for valid frame headers is unlikely to give false positives
because every frame header is at least 9 bytes long, contains a
14 bit sync code and a 8 bit checksum over the first 8 bytes.

Fixes bug #631200.

Sebastian Dröge 396501784c flacparse: Really post tags only after the initial newsegment event 
The first newsegment event will be send by the first call to
gst_base_parse_push_buffer() if necessary, posting the tags
before that is not a good idea. Instead do it from the
GstBaseParse::pre_push_buffer vfunc.

Tim-Philipp Müller 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.

Sebastian Dröge 7e581aebe2 flacparse: Fix uninitialized variable compiler warnings 
These warnings are wrong, the variables are only used if they were
initialized by the bit reader.

Arun Raghavan 2d699010e9 baseparse: Fix debug output 
We lose the reference to the buffer after gst_pad_push(), so the debug
print should happen before.
