[MPlayer-users] using mencoder for the Archos Multimedia Jukebox

Hello All,

I'm trying to use mencoder to convert my various media formats over to a
readable format for my Archos jukebox.  I think I'm close, but the thing
is still not displaying the video.  I'm testing with one of my matrix
preview quicktimes and running with the following command (among

mencoder matrix4.mov -oac mp3lame -lameopts cbr:preset=128 -ovc lavc
-lavcopts vcodec=mpeg4:vbitrate=800 -vop scale=352x288 in.avi -o out.avi

I think that what's stopping it from playing is that it may be still
compressed and archos may not handle this. I couldn't find much detail
in the list archive and the recommendations given don't work for the
archos.  Here's the exact text from the manual that I'm trying to put
into the mencoder command:

"The jukebox multimedia can play back MPEG4 Simple Profile video files
in AVI format.  Maximum resolution is CIF (352 x 288 pixels) @ 30
frames/sec.  Larger resolution files or non-standard MPEG4 files will
not be played.  The sound track, if any, must be in MP3 format."

I have no idea what their supposed standard means to archos.

I'm using the codecs provided by mencoder.  I've experimented with:

They do ship some canned videos on the device and here are a few
snippets from mplayer's output when playing one:

VIDEO:  [DX50]  352x160  24bpp  25.00 fps  1132.9 kbps (138.3 kbyte/s)
Opening video decoder: [ffmpeg] FFmpeg's libavcodec codec family
Selected video codec: [ffodivx] vfm:ffmpeg (FFmpeg MPEG-4)

I'm running Version: 0.90rc5-2.95.4 on Debian sarge.

Any thoughts? I've never had to encode before buying this device so
maybe I'm missing something obvious.
