1.51 +
1.52 +file://file_name mux vcodec vbitrate fps acodec abitrate width height options
1.53 +dvd://title_number mux vcodec vbitrate fps acodec abitrate width height options
1.54 +
1.55 +-> PLAY DESCRIPTION
1.56 + |-> used to start transcoding and streaming of file
1.57 + |-> must be used just if SETUP was used before
1.58 + |-> after it, _must_ send STOP
1.59 +
1.60 +-> STOP DESCRIPTION
1.61 + |-> used to stop transcoding and streaming process
