Example launch line

 gst-launch-1.0 webmmux name=mux ! filesink location=newfile.webm         \
   uridecodebin uri=file:///path/to/somefile.ogv name=demux                \
   demux. ! videoconvert ! vp8enc ! queue ! mux.video_0    \
   demux. ! progressreport ! audioconvert ! audiorate ! vorbisenc ! queue ! mux.audio_0

This pipeline re-encodes a video file of any format into a WebM file.

   videotestsrc num-buffers=250 ! video/x-raw,framerate=25/1 ! videoconvert ! vp8enc ! queue ! mux.video_0 \
   audiotestsrc samplesperbuffer=44100 num-buffers=10 ! audio/x-raw,rate=44100 ! vorbisenc ! queue ! mux.audio_0
