Vincent Penquerc'h b19a5ea1f3 tsdemux: do not keep a dangling pointer 
When removing the current program, it will get freed by the
hash table removal callback, so ensure we clear our pointer
to it.

Fixes a crash later on in gst_ts_demux_push trying to access it.

Youness Alaoui 818762e8fc tsdemux: do not send a new-segment on stream removal 
When a program is changed, stream_added is called which sets the
need_newsegment to TRUE, then stream_removed is called, which calls
the flush_pending_data, which checks for the newsegment and causes
it to send a new-segment.

We must not send the newsegment when flushing the pending data on the
removed stream. We should only push it when flushing data on the newly
added streams (after they finish parsing their PTS header)

Youness Alaoui 382710e200 tsdemux: Fix newsegment when switching programs 
If a program/stream is changed, then a newsegment is sent which must
not be the same as the base segment since it happens later. We must
shift the start position by the time elapsed since the newsegment
and the current PTS of the stream
 2011-08-22 16:01:17 +02:00

Edward Hervey 5c77682dab tsdemux: Take into account upstream newsegment events 
If the incoming newsegment event was in time, use that position value
for the downstream newsegments.

Edward Hervey adfb090b59 mpegtsbase: Remove programs on EOS 
Allows subclasses to properly flush out pending data.
 2011-08-01 15:46:12 +02:00
Edward Hervey 57279cdd24 tsdemux: Refactor stream/program removal 
The program_stopped vmethod was called before stream_removed vmethod
was being called. Since we only did stream-related operations in there,
we just remove the program_stopped vmethod and do everything in the
stream_removed one.

Also, make sure we flush out all pending data before sending EOS.

Nicolas Dufresne cbc0a2f056 mpegtsbase: Prevent stack gardening by using the right type 
stream_type is stored as guint inside the GstStructure but was retreived
using valist with a pointer to guint16. This would cause stack gardening
when code is compiled without optimisation (e.g. in -O0 the compiler wont
pad the stack to optimise out required mask).

Edward Hervey 634d29cd88 mpegtsbase/tsdemux: Fix stream/pad activation order 
We first activate new streams before shutting down old ones.
We emit no-more-pads after we add new streams and emit EOS before
removing old ones.
Also cleanup/refactor a bit more of the code accordingly
 2011-07-25 18:56:49 +02:00
Edward Hervey d0e8427b4e pesparse: Fix stuffing byte handling 
We in fact get the size of the header (including stuffing bytes), therefore
use that instead of trying to skip 0xff bytes ourselves since some media
streams do start with 0xff (like mpeg audio's initial 0xfff).
 2011-07-20 19:19:13 +02:00
Alessandro Decina 2b7e9abc59 mpegtsdemux: fix compiler warnings 2011-07-20 08:59:25 +02:00

Edward Hervey 2b127601e9 mpegtsbase: Avoid double removal of streams 
This can happen if the PCR pid is the same as a audio/video PID.
 2011-07-19 09:49:40 +02:00
Edward Hervey b170b2020c mpegtsbase: Add a GList of streams to the program 
Allows faster iteration of all program streams.

We still keep the Array to allow fast retrieval of stream by PID.

Edward Hervey dc18e2b16d mpegtsbase: Use a bit array instead of an array of gboolean

Edward Hervey 9f1511e998 tsdemux: Fix newsegment creation for push mode 
And all relevent comments to what it should be doing, refactor everything
a bit. Still not perfect ... but better.

Fixes #654657

Alessandro Decina d439f2d38d mpegtsbase: actually set seen_pat=TRUE when we see a PAT 2011-07-15 00:03:52 +02:00
Edward Hervey a82483e367 mpegtsbase: Split up whether we saw a PAT and its offset 
Fixes the issue with streams that don't set an offset on their buffers,
like those coming from hlsdemux.

Fixes #653481

Olivier Crête ca7a512739 mpegtsdemux: Restore erroneously removed data++
