GNOME Bugzilla – Bug 336528
testing input plugin doesn't work
Last modified: 2007-01-07 11:48:38 UTC
Please describe the problem: On latest Ubuntu Dapper with gnome-media 2.14.0, gstreamer 0.10.4, gst-plugins-base 0.10.5 it's not possible to test the selected input plugin unless it's 'silence' or 'testaudiosrc'. The error message is "Failed to construct test pipeline for 'ALSA - Advanced Linux Sound Architecture'" or the equivalent for OSS. Setting the output plugin to something else doesn't change anything. Running the gstreamer-properties pipeline with gst-launch works fine: gst-launch-0.10 alsasrc ! audioconvert ! audioresample ! alsasink Setting pipeline to PAUSED ... Pipeline is live and does not need PREROLL ... Setting pipeline to PLAYING ... New clock: audioclock0 Caught interrupt -- Pausing pipeline. Pipeline paused. WARNING: Element "pipeline0" warns: pipeline interrupted GST_DEBUG=3 output of gstreamer-properties with alsasrc: http://librarian.launchpad.net/1894688/gst-alsa.txt GST_DEBUG=3 ouput of gstreamer-properties with osssrc: http://librarian.launchpad.net/1894693/gst-oss.txt Steps to reproduce: 1. start gstreamer-properties 2. test the input plugin Actual results: it fails with the error mentioned above Expected results: it would work as expected Does this happen every time? yes Other information: Ubuntu Bug: https://launchpad.net/distros/ubuntu/+source/gnome-media/+bug/37184/+index
I can confirm this bug, and I've seen at least two other people on Ubuntu Forums having similar problems.
Any messages on the commandline? It works for me... What kind of soundcard do you have? Is it capable of being opened multiple times (test by doing on the commandline "gst-launch sinesrc ! audioconvert ! audioresample ! alsasink device=hw:0" in two different terminals at the same time).

This seems to be fixed now... probably by one of the many gstreamer updates since then or gnome-media 2.16 or 2.17
