.SH DESCRIPTION
|
|
||||||
.I mencoder
|
|
||||||
MEncoder (MPlayer's Movie Encoder) is a simple movie encoder, designed to
|
|
||||||
encode MPlayer-playable movies (AVI/DVD/VCD/VOB/MPG/MOV/VIV/NET) to other
|
|
||||||
MPlayer-playable formats (see below). Currently it's in beta stage, and encodes
|
|
||||||
only to DivX4 (1 or 2 passes) video, PCM/MP3/VBRMP3 audio. Also has stream
|
|
||||||
copying abilities. In the future, there will be cropping, resizing filters, and
|
|
||||||
other interesting stuff.
