Question encoding picture frames using mencoder


Hi-
I have been browsing through forums and have found that many people have a similar problem, but it never seems to be fully addressed. I hope someone can help:

______________________________________________________________________________
{30 Tue}mencoder -mf on:w=800:h=600:fps=25 -ovc divx4 -o test.mpg \*.jpg
MEncoder 1.0pre7try2-3.3.2 (C) 2000-2005 MPlayer Team
CPU: Advanced Micro Devices Athlon MP/XP/XP-M Barton (Family: 6, Stepping: 0)
Detected cache-line size is 64 bytes
CPUflags: Type: 6 MMX: 1 MMX2: 1 3DNow: 1 3DNow2: 1 SSE: 1 SSE2: 0
Compiled for x86 CPU with extensions: MMX MMX2 3DNow 3DNowEx SSE

File not found: 'frameno.avi'
Failed to open frameno.avi
-mf on is deprecated, use mf:// instead.

Exiting... (error parsing cmdline)
______________________________________________________________________________

I have tried several variations of commands using different input file types (.ppm would be ideal) and other variations but always come back to the frameno.avi error. I am trying to encode a series of computer generated star simulation images that tend to form messy movies with encoders such as mpeg2enc due to the high level of pixellation.

Thanks

well the error there clearly tells you to replace -mf on:w... with mf://on:w... i'd suggest you do that, and post any other errors after that.

I tried using mf:// as well with this result:

{31 Wed}mencoder mf:// on:w=800:h=600:fps=25 -ovc divx4 -o test.mpg \*.jpg

Failed to open frameno.avi

[demuxer] mf support.
[demux_mf] file type was not set! (try -mf type=xxx)
============ 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.

Exiting...

I also tried a combination of mf:// and -mf as seen on the first web site that comes up when "mencoder jpeg" is Google-d (I am not permitted to post an URL).

Thanks!
