[SOLVED] Possibly missing mpegts* in gst-plugins-bad?

whisperer · 2014-04-24 15:28:04

I'm currently working on a DVB streaming project and it seems like there is a problem with the gst-plugins-bad package. This package is supposed to provide mpegts-plugins e.g. "mpegtsdemux", "mpegtsparse" and so on. However no application on my system can find "mpegtsdemux" or "mpegtsparse". I have installed "gstreamer1.2.4-1" and also "gstreamer0.10.23-8". Of course I have installed "gst-plugins-bad" for both versions of gestreamer and even all of the other plugin packages. I have also read that it is absolutely ok to to run both versions of gstreamer on the same system.

First Example:

I tried to install Gnome DVB Daemon. Both, the version from AUR and from here fail with the error

checking GStreamer 0.10 inspection tool... yes
checking GStreamer 0.10 mpegtsparse plugin... no
configure: error:
Cannot find required GStreamer-0.10 plugin 'mpegtsparse'.
It should be part of gst-plugins-bad. Please install it.

But I have already installed gst-plugins-bad for gstreamer-0.10

Second Example:

gst-launch dvbsrc modulation="QAM 64" trans-mode=8k bandwidth=8 frequency=514000000 code-rate-lp=AUTO code-rate-hp=2/3 guard=4  hierarchy=0 pids=100:256:257 ! mpegtsdemux name=demux ! queue max-size-buffers=0 max-size-time=0 ! mpeg2dec ! xvimagesink demux. ! queue max-size-buffers=0 max-size-time=0 ! mad ! alsasink

results in:

WARNING: erroneous pipeline: no element "mpegtsdemux"

and gst-launch is terminated

I searched a lot on google and I also searched the forum, but couldn't find anything helpful. I would appreciate any help or ideas.

Ok, I actually found the solution for the second example:
renaming mpegtsdemux to tsdemux seems to work. I still have to find out if tsdemux does the same as mpegtsdemux. Maybe they just changed the name. That would also be an explenation why the installation of Gnome DVB Daemon does not work. I will post again as soon as I know more.

To some extent you can check what gstreamer is doing with naming with gst-inspect:

~ > gst-inspect-1.0 | grep tsdemux
mpegtsdemux:  tsparse: MPEG transport stream parser
mpegtsdemux:  tsdemux: MPEG transport stream demuxer

Thank you. I didn't know that you can use gst-inspect without any parameters. The output (mine is the same as yours) explains why there is no mpegtsdemux.

Actually I was mislead by the example from the comments of dvbsrc here. Ok, probably not the best source ;-)

Regarding the "First example" from my post:
Gnome DVB Daemon uses/searches for the mpegtsparse, so I assume that the plugin names really did change.
Gnome DVB Daemon should be using/searching for tsparse instead of mpegtsparse. I will write the developers a bug report later. Problem Solved.
