Hello Guillaume,
thank you for your answer! I understand you are the one who is taking
care about the docs?! Really nice - they are great! I want to try to
give you more information.
>problem. Helmut, what version of MPlayer are you using? Are you using

I am using 1.0pre7try2.
I started from a set of .tif files. Converted them to .jpg.
*|$> for i in *.tif; do convert -depth 8 -colorspace rgb $i `basename $i .tif`.jpg; done|
*
*Now I verify the result. I do

*$> mplayer -v mf://*.jpg -mf fps=25*

and mplayer is playing perfectly fine!
I understand without -vc ijpg mplayer chooses lavc's ffmpeg to play the "mf://*.jpg" source. However ijpg is the better choice.
Now as for the mencoder, I understand it works "in two steps". Correct me if I'm wrong. First mplayer generates a stream of the source and second this stream is fed to mencoder which generates the desired output file. So I can use the -vc option with mencoder to tell it how it should read the source, like
$> mencoder mf://*.jpg -mf fps=25 -vc ijpg -ovc lavc -lavcopts vcodec=mpeg4 -oac copy -o output.avi
So I suggest it should be very useful for a newbee (like me) to understand from the examples in the mencoder mjpg / mpng / mtga Docs section that this is possible (and maybe sometimes necessary).
hope this is of use for others:-)! Thank you once again.
All the Best,
Helmut
