Please attach the output of that in a file and not > include it inline inside the mail :) Ok, it's a different error because I've forgot to export DISPLAY, sorry :-P I've attached the output with "GST_DEBUG=omx*:5,openmax*:5" in gst-launch_playbin2_test_avi_debug_output > > > > > > > > > Also try if one of these commands works without errors, and if it > > > > doesn't provide debug logs for these too. > > > > > > > > gst-launch-0.10 filesrc location=/path/to/file ! avidemux ! queue ! > > > > omxmpeg4dec ! fakesink -v > > > > > > > > gst-launch-0.10 filesrc location=/path/to/file ! avidemux ! queue ! > > > > omxmpeg4dec ! queue ! autovideosink -v > > > > Hmm... both commandlines say: > > WARNING: erroneous pipeline: no element "omxmpeg4dec" > > > > Same error occurs when I try it with "omxmpeg4dec0" or "omxmp3dec" > > Ah sorry, the name is actually nv_omx_mpeg4dec. Can you retry with that? Now it starts, but fails with the same error as playbin2 does.
