[gst-devel] mpeg transport stream "stuck"

[Dan Taylor]

I'm trying to use GStreamer and its associated plugins to play an MPEG
Transport Stream (TS) that I captured.  FWIW, I can play the stream, as
is, with mplayer, but mplayer has limitations that make it unusable as a
long-term solution.

 

The TS has several programs and I want to play one of them.  This is
simply a development step on the way to using a DVB-T/ATSC front end to
source the TS.

 

I have used

"gst-launch filesrc location=file.ts ! flutsdemux name=d  d.audio_0801 !
queue ! filesink location=0801.mpa d.video_0800 ! queue ! filesink
location=0800.mpv"

to extract an audio and video PID to files, so the demuxer seems to be
working.

I have used

"gst-launch filesrc location=0801.mpa ! decodebin ! audioconvert !
alsasink"

and

"gst-launch filesrc location=0800.mpv ! queue ! mpeg2dec !
ffmpegcolorspace ! xvimagesink"

to successfully play the individual files, but when I combine them with

gst-launch -m filesrc location=file.ts ! flutsdemux name=d  d.audio_0801
! queue ! decodebin ! audioconvert ! alsasink  d.video_0800 ! queue !
mpeg2dec ! xvimagesink

a window is opened and the first frame displayed, but neither does the
video continue, nor is there any audio.  I can kill the X window, and
there are the messages at the end of the post.

Any ideas where I should begin debugging this?  Is there a clock/sync
problem, perhaps?

Thanks.
