Unable to play mpeg video using gst-launch

[Soeren Grunewald]

Hi,

you should check what playbin does, try:

$ GST_DEBUG_DUMP_DOT_DIR=. gst-launch playbin2 uri=file://...
$ dot -T svg -O *gst-launch.PAUSED_PLAYING.dot -o pipe.svg && eog pipe.svg

This will show you the formats detected and elements are choosen by 
playbin. Maybe this will help you.
