[MPlayer-users] Re: trouble converting ppm to mpeg - repost

Fri Sep 19 19:55:14 CEST 2003

[summary: I think I've tried what you suggested and it isn't working.
  what am I doing wrong?  do I have a buggy release?]

when I do a "man mplayer" I don't see exactly what you see.  I see
    mencoder "mf://*.jpg" -mf fps=25 -o output.avi -ovc divx4
not the example you are sending me.
Also I also don't see any mention of an "on" option for -mf.
(I'm running MPlayer 1.0pre1-3.2.2).  I find the example I do see
confusing, since the man page talks about -mf, not "mf://".
I'm also confused by which options are "global" and go at the front and
which are supposed to come immediately AFTER the file name.  Looking at my
man page it looks like almost all options to mencoder should come before
the file names
    mencoder [options] [ file | URL | - ] [-o file]

However, I had thought that filename expansion might be part of the problem
so I had tried just listing all the files on the command line, that didn't seem
to help.

If I do as I think you are suggesting:
    mencoder \*.jpg -mf on:fps=2:type=jpeg -ofps 2 -ovc lavc -lavcopts   \
	vcodec=mpeg1video -of mpeg -v -o movie.mpg
I get:
	MEncoder 1.0pre1-3.2.2 (C) 2000-2003 MPlayer Team

	File not found: 'frameno.avi'
	Failed to open frameno.avi
	Reading config file /home/lml/.mplayer/mencoder: No such file or directory
	-mf on is deprecated, use mf://files instead

However, if I leave the "on" option out I no longer get the "deprecated" warning

    mencoder -mf fps=2:type=jpeg -ofps 2 -ovc lavc -lavcopts vcodec=mpeg1video \
		-of mpeg -v  \*.jpg -o movie.mpg

	...
  	File not found: '*.jpg'
	Failed to open *.jpg
	Cannot open file/device.
	Exiting...

So this looks like it STILL isn't expanding out the "*".  I tried with quotes around
it ("*.jpg"), same error message.  So I tried to manually
list the files:
    mencoder -mf fps=2:type=jpeg -ofps 2 -ovc lavc -lavcopts vcodec=mpeg1video -of mpeg \
        -v movie0.jpg movie1.jpg movie2.jpg movie3.jpg -o movie.mp

now I get a different error message:

So I'm still stumped!
