Hello.
I must start by saying thanks for all the work put into MPlayer. It is the best
player around =)
I think I have found a bug in mencoder.
It segfault when I try to do encoding from multiple files.
The result is the same with both divx4 and libavcodec.
I have also tried a diffrent set of jpeg-files, but the files should be ok.
`mplayer -mf on \*.jpg` plays with no problem.
If you need more information than the following please ask.
