[MPlayer-users] convert bmp to avi

[Adrian Boeing]

Hi,

I'm trying to convert a sequence of bmp files into an AVI, preferably divx.

At the moment I'm just trying to make an mpeg1 out of them using this:
mencoder mf://frame*.bmp -mf w=800:h=600:fps=25:type=bmp -ovc lavc 
-lavcopts vcodec=mpeg1video -oac copy -o output.avi

However I get this error message:
MF file format detected.
[mf] search expr: frame*.bmp
[mf] number of files: 13 (52)
[demux_mf] unknown input file type.
============ Sorry, this file format is not recognized/supported 
=============
=== If this file is an AVI, ASF or MPEG stream, please contact the 
author! ===
Cannot open demuxer.

Am I doing something wrong? Would anyone be able to tell me what the 
correct command line should be?

Thanks!
