MEncoder can create MPEG (MPEG-PS) format output
files. It is probably useful only with
libavcodec
's
mpeg1video codec, because players - except
MPlayer - expect MPEG-1 video, and MPEG-1 layer 2 (MP2)
audio streams in MPEG files.
This feature is not very useful right now, aside that it probably has many bugs, but the more importantly because MEncoder currently cannot encode MPEG-1 layer 2 (MP2) audio, which all other players expect in MPEG files.
To change MEncoder's output file format, use the -of mpeg option.
Example:
mencoder -of mpeg -ovc lavc -lavcopts vcodec=mpeg1video -oac copyother_options
media.avi
-ooutput.mpg
