I don't know what that program does.
There is -endpos, but it works very badly for this use-case.
The way you are supposed to do is by either
1) using -slave and sending a "quit" command - though I am not sure this
works with -dump*
2) sending a SIGINT signal to the process
while both are also possible on Windows, to my knowledge they are a
huge pain to do unless you have e.g. cygwin installed

A sample would be useful to allow us to fix it.

MPlayer seems to incorrectly think it is a MPEG-PES file.
-demuxer lavf or -demuxer audio will probably work around it.
