3c73d29162 mpegtsbase: Adapt to new packetizer behaviour 2012-05-22 17:43:38 +02:00
Edward Hervey
c6035d403c mpegtspacketizer: Avoid usage of GstBuffer internally 
The overhead of creating/using 188 byte GstBuffer from GstAdapter
is too expensive.
We now peek the next packet, and provide a data/size which is only
valid until the packetizerpacket is cleared.

In addition, cleanup all the internal code to deal with that new
behaviour and remove double-checks which are no longer needed.

The section_length is now the corrected section_length (i.e. with
the additional 3 bytes).

Avoid using gst_adapter_prev_timestamp and instead track
the timestamp ourself.

6d01f5f1b3 mpegtspacketizer: Detect PCR wraparound in skew code 
If the received PCR is going backwards (by a safe margin), include
that wraparound for further calculation.

5536bcf8b8 tsdemux: flush on pusi only for payload packets 
Data should not be flushed out of the tsdemux because a payload unit start
indicator (pusi) is seen in a adaptation only ts packet. If the package contains no
payload a pusi does not indicate a new PES packet, but PSI information, etc.
This fixes playback of several TS files which contain ts packets without
payload but with pusi set to 1.

e75612c3fd tsdemux: Don't queue data for streams that don't have a pad 
This would result in an error further down, and it also avoids processing
for that data which we wouldn't be using anyway.

We need to reset the stream on a flush or else old packets could be added to the

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).

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.
