[MPlayer-users] How to extract a .WAV file from part of a dump file, Not Yet.

[Martin McCormick]

I am really starting to feel dense. I have installed subversion
which works like a charm and then I got the mplayer sources
which built mplayer, also just fine and I am, in fact, listening
to an Internet radio station as I write this message so
things are not too dead in the water. I am still, however,
ending up with a very short .wav file that contains only the
first chunk of decoded audio and none of the segment I was
after.

-rw-r--r--  1 martin martin 65580 Jun  7 11:34 ./pgmaudio/output.wav

The file is exactly this length no matter what I put as the
endpos value. The command is as follows:

mplayer -vc null -vo null -ao pcm:file=output.wav -ss 8:54:15 -endpos 180 str
eam.dump

This goes 8 hours, 54 minutes and 15 seconds in to the dump file and
retrieves 180 seconds or 3 minutes which should be in the
output.wav file.

Here is the mplayer version message I get now on startup:

That's it. So close, but no joy.
