Gstreamer in an embedded Linuxdistribution

[Stephan Raue-2]

Hi all,

I'm new to this list and I have a question.

I'm working on a project for an embedded Linux distribution for a HTPC.
My goal is to run the Elisa Media Center on a minimal Linux. Elisa is
based on Gstreamer.

Now i have various problems running Gstreamer:

When i want play a internet videostream i became elisa says:

Gstreamer error: resource not found

and when i am playing a local file: Your gestreamer installation is
missing a plugin an elisa.log says:

WARN  MainThread      default                     Mar 19 13:29:43  
Gstreamer Your GStreamer installation is missing a
plug-in.:gstplaybasebin.c(1673): gen_source_element ():
/GstPlayBin:playbin0:
No URI handler for file (elisa/plugins/poblesec/player_video.py:535)

where i can see which plugins are missing?

i have compiling everything from source including
gst-plugins-{base,bad.good,ugly} and gst-ffmpeg.

when i am play an e.g. Audiofile i become often error like this (from
elisa.log)

DEBUG MainThread      audio_player_controller     Mar 19 12:44:29  
Received metadata from player {'album': 'High Mud Leauder',
'track-number': 2L, 'artist': 'High Mud Leauder', 'title': 'Admiral',
'duration': 171781000000L, 'genre': 'Rock/Pop'}
(elisa/plugins/poblesec/player_video.py:1119)
WARN  MainThread      default                     Mar 19 12:44:29

gst_alsasink_open (): /GstAlsaSink:audiosink-actual-sink-alsa:
Playback open error on device 'default': Invalid argument
(elisa/plugins/poblesec/player_video.py:535)

can anyone help me?

sources to build my distribution or see how i compiled gstreamer,
plugins and other you can find at
http://bazaar.launchpad.net/~sraue/openelec/devel/files when you need it
i can upload an image of this Distribution (ca. 40MB)

You probably should try to launch a simple GStreamer pipeline with
playbin on your distro and you will see quickly the missing plugins.

Indeed Elisa uses playbin and a simple :

gst-launch-0.10 playbin uri=file:///home/user/file.mov

should work before Elisa can play that file.

Obviously you might have some problems with the video and audio sinks if
you don't use Xorg.

You need to explicitly set elements to the NULL state before
dropping the final reference, to allow them to clean up.

Seems your alsa driver is not working well.
You need to check your ALSA with "aplay xx.wav", or set OSSSink into
playbin if alsa is not available.
