issues with mpeg{ts,ps} demux

Hi,

On my fedora 12 pc i have i have installed,
gstreamer-0.10.27
gst-plugins-base-0.10.27
gst-fluendo-mpegdemux-0.10.23
(and the other gstreamer packages)

If i try to play an MPEG Program stream (H.264 BP Video and MPEG1
Layer 2 Audio) using the following pipeline
gst-launch filesrc location=file.mpg ! flupsdemux name=demux ! queue !
ffdec_h264 ! xvimagesink demux. ! queue ! mad ! alsasink

The pipeline goes into the playing state, but nothing ever gets
rendered on the screen.
Hoever if i specify queue limits on the queue before the ffdec_h264
plugin, the pipeline works correctly.

gst-launch filesrc location=file.mpg ! mpegpsdemux name=demux ! queue
max-size-buffers=0 max-size-time=0 max-size-bytes=5242800 ! ffdec_h264
! xvimagesink demux. ! queue ! mad ! alsasink

I don't know what the issue here is. I have never encountered this
behaviour with other pipelines, only with gst-fluendo-mpegdemux for
both program as well as transport streams.

Please find my test stream here:

Have you tried mpegpsdemux instead? Do you see anything when setting
sync=false on xvimagesink. If so the psdemuxer has a timestamp issue.

Hi,
Yes i have tested it with mpegpsdemux which is in
gst-plugins-bad-0.10.18 as well as flupsdemux.
Both yield the same behaviour.

Re: issues with mpeg{ts,ps} demux

Hello,

I believe the issue comes up when there is an Audio/Video delay of more
than 1 second.

I had this issue also with some certain video streams. My explanation
was that the default queue size is 1 second and when there is a delay
between the audio and video data of more than one second, the video
queue overruns and blocks the demuxer.
