Gil Pedersen 095a17ad03 mpegtsdemux: fix memory leaks 
Fixes https://bugzilla.gnome.org/show_bug.cgi?id=674393
 2012-04-20 11:25:31 +02:00
Julian Scheel 1059905237 tsdemux: Set currentlist to NULL after free. 
This prevents double free of currentlist is some circumstances.

Sebastian Dröge cda192b3b7 gst: Update for GST_PLUGIN_DEFINE() API changes 2012-04-05 18:02:56 +02:00
Alessandro Decina f4b292f994 tsdemux: set correct newsegment fields on _TIME seeks 
Forward the seek rate and set NS.start to the seek target so that decoders can
apply clipping where necessary.

Edward Hervey 85878c142e mpegts: Switch rank of mpegtsdemux and tsdemux 
More effort has been put lately in tsdemux and works in more use cases
 2012-03-05 09:46:17 +01:00
Edward Hervey c557f71756 tsdemux: Push packets as early as possible 
When the PES header tells us how big the outgoing packet is, push the
packet downstream as soon as we have the specified size instead of waiting
for the beginning of the next packet.
Reduces latency and removes issues with very sparse streams (like subtitles
and subpictures).

Tim-Philipp Müller 0bb5a01639 tsdemux: fix confusing variable name 2012-03-03 15:47:01 +00:00
Edward Hervey 01f5f62d95 tsdemux: Fix segment start position 
If we *really* can't figure out the first start position, that most
likely means the data to push out doesn't have any timestamp.
Use a default value of 0 then
 2012-03-02 17:19:45 +01:00
Edward Hervey a3ae51be29 mpegtsbase: Flush out the packetizer on flushing seeks 
... else we end up with bogus data/offsets
 2012-03-02 17:19:45 +01:00
Thibault Saunier ece4dfc3c6 tsdemux: Activate pads only when receiving data for the stream 
https://bugzilla.gnome.org/show_bug.cgi?id=670921
 2012-03-02 17:19:45 +01:00
Edward Hervey 671550714f mpegtsbase: Check harder for program changes 
And don't just rely on the section crc/version_number changing to
indicate that the program actually changed.
 2012-03-02 10:54:48 +01:00
Edward Hervey 097f09b823 mpegtsbase/tsdemux: Refactor seek and segment handling 
All calculations go through the mpegtspacketizer
Remove unused variables/code
 2012-03-01 18:15:51 +01:00
Edward Hervey 77ece06a3f mpegtsbase: Error out on EOS without any pad 
Avoids ending up with hanging pipelines
 2012-03-01 18:15:51 +01:00
Edward Hervey a4899af8d6 mpegtspacketizer: Offset calculation 
Allows PCR<=>PTS<=>offset estimation/calculation
Right now the calculation is very naive, but can be extended later on
without disrupting the code in tsdemux/mpegtsbase
 2012-03-01 18:15:51 +01:00
Edward Hervey 39cc29a7d2 mpegtspacketizer: clock fix and minor addition 
* Don't take into account packets that arrived at the same time as
  previous ones for clock skew estimation
* Add convenience method for processing the next ts packet
 2012-03-01 18:15:51 +01:00
Edward Hervey c10fc17a1e Revert "mpegtsdemux: Not apply various time the same PMT to a program when repetead" 
This reverts commit 8cb0e87f56.

mpegtspacketizer already checks if it's a new PMT or not
 2012-03-01 18:15:51 +01:00
Edward Hervey d920d9d64f tsdemux: Remove all seeking code 
It was more than bogus
 2012-03-01 18:15:51 +01:00
Thibault Saunier 5c2e6dc512 mpegtspacketizer: catch section lengths extending past the buffer length 
This is probably the cause for an occasional crash while streaming
MPEG. Blind fix after staring at the code and following logic, so
may or may not fix the issue, I cannot test.

Thibault Saunier 58a210e3d3 mpegtspacketizer: support more character set encodings 
Support UTF-16BE, EUC-KR (KSX1001), GB2312 and ISO-10646/UTF8 text
encoding and fixed new line for multibyte encoding

Thibault Saunier 8cb0e87f56 mpegtsdemux: Not apply various time the same PMT to a program when repetead 
Sometimes their are several times the same PMT applying to a same program in a stream,
tsdemux was totally baffled when this was happening, we now keep the one we
already applied so it works properly.

the stream flowing.
