dvbsrc/dvbbasebin problems

[Krzysztof Adamski-2]

I'm trying to play streams (at least FTA) from my DVB-S card using
gstreamer but after couple hours of testing i'm still having problems.
Hope someone can help me..

First I was trying to get video using dvbsrc.. it works when i'm saving
it to file with following pipeline:
gst-launch-0.10 -m dvbsrc adapter=0 frequency=10719000 pids=163:92 \
  polarity=v symbol-rate=27500 ! filesink location=/tmp/1.ts

Now i'm able to play the file (with smooth video) using:
gst-launch -m filesrc location=/tmp/1.ts ! mpegtsdemux es-pids=163:92\
 !  mpeg2dec ! ffmpegcolorspace ! xvimagesink

So far it's good, the problems starts when I'm trying to watch live
wideo. I'm using following pipline to do that:
gst-launch-0.10 -m dvbsrc adapter=0 frequency=10719000 pids=163:92 \
  polarity=v symbol-rate=27500 ! mpegtsdemux es-pids=163:92 ! mpeg2dec \
  ! ffmpegcolorspace ! xvimagesink

The video is shown but it is not smooth.. it shows 1 frame, then it
stops for a while (sometimes half of secound, sometimes 2 seconds, it
depends) and play another frame.. sometimes it works fine for a second
or two and then stops again and so on.. Any ideas on why it's working
like this?

I have also tried using dvbbasebin with slightly changed pipline (using
program-numbers instead of pids):
gst-launch-0.10 -m dvbbasebin adapter=0 frequency=10719000 \
program-numbers=4404 polarity=v symbol-rate=27500 \
.program_4404 ! filesink location=/tmp/1.ts

While running that i'm getting some messages from mpegtsparse0 with eit
and sdt elements but and the file /tmp/1.ts seams to contain only this
packets (it has 8kb after a minute of playing and viewing it in ghex
shows this are MPEG packages with some text information about channels).
Is this EPG or something? Why there is no video?

Anybody could point me out what I'm doing wrong?

Hi,

    There is nothing wrong in both the pipeline, i tried then on my system and they worked fine. Just try running szap and lock to a perticular frequency and then try the pipeline.
     Yes the message you are getting are the EPG information.

You should not use es-pids, instead you should make sure you always
record the pat and pmt inside the ts also.

Same as above.

Do:

set GST_DEBUG=dvb*:5 and then run your dvbbasebin pipeline again with
stdout and stderr redirected to a file, ctrl-c after 5 mins and send
me the file.

Most likely you have set the wrong program number (equivalent to
service id or sid) for the channel you want.

You mean you where able to watch life (smooth) video with this pipeline:
gst-launch-0.10 -m dvbsrc adapter=0 frequency=11158000 pids=353:354
polarity=v symbol-rate=27500 ! mpegtsdemux es-pids=353:354 ! queue !
mpeg2dec ! ffmpegcolorspace ! xvimagesink
?

This doesn't change anything. Gst is locking to the frequency without
szap help however, i can see that from messages like this:
Got Message from element "dvbsrc0" (element): dvb-frontend-stats,
status=(int)31, signal=(int)48059, snr=(int)48573, ber=(int)150,

How can i make sure it is? When not using es-pids, i'm getting following
error:
gst-launch filesrc location=/tmp/1.ts ! mpegtsdemux !  mpeg2dec \
 ! ffmpegcolorspace ! xvimagesink
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
ERROR: from element /GstPipeline:pipeline0/GstMpegTSDemux:mpegtsdemux0:

(): /GstPipeline:pipeline0/GstMpegTSDemux:mpegtsdemux0:
No valid streams found at EOS
ERROR: pipeline doesn't want to preroll.
Setting pipeline to NULL ...

The same works with es-pids. The file has 60MB. What I'm doing wrong,
then?

I've run this on Ubuntu Janunty, here is the full log:
http://vps.japko.eu/gst_full_log.txt

most of the log lines are something like this however:

dvbsrc gstdvbsrc.c:952:gst_dvbsrc_create:<dvbsrc0> Reading from DVR

So i removed this lines from the log to make it more compact and here is
what it left:

And I'm also pasting it here for the record (removing first 4 colums):

You mean you where able to watch life (smooth) video with this pipeline:
gst-launch-0.10 -m dvbsrc adapter=0 frequency=11158000 pids=353:354
polarity=v symbol-rate=27500 ! mpegtsdemux es-pids=353:354 ! queue !

This doesn't change anything. Gst is locking to the frequency without
szap help however, i can see that from messages like this:
