Description

Using mencoder with resample type of 1 or 2 causes 100% cpu usage.

I'm making a blind stab in the dark with the component type, I tried to send the bug without it selected but it wants something to be there. Feel free to correct that...

An example of something that works:

mencoder -o "halo.pcm" -of rawaudio -oac pcm -ofps 30000/1001 -af channels=2,volnorm,resample=48000:0:0 -vf harddup -ovc copy "halo 2010-01-20 00-04-33-62.avi"

That above command line works.

This and the following do not. Any ideas what's wrong?

mencoder -o "halo.pcm" -of rawaudio -oac pcm -ofps 30000/1001 -af channels=2,volnorm,resample=48000:0:1 -vf harddup -ovc copy "halo 2010-01-20 00-04-33-62.avi"

*freezes at 100% cpu usage, does nothing else, have to ctrl-c or kill to make it go away*

mencoder -o "halo.pcm" -of rawaudio -oac pcm -ofps 30000/1001 -af channels=2,volnorm,resample=48000:0:2 -vf harddup -ovc copy "halo 2010-01-20 00-04-33-62.avi"

*same as before, freezes at 100% cpu usage, have to ctrl -c or kill to stop it*

Only bug reports against SVN are accepted.
Apart from that, your command lines all work for me with the files I have (with SVN version of course).
If you can reproduce the version with SVN, I suggest you upload a sample to reproduce the issue with or find one in http://samples.mplayerhq.hu that shows the issue.
Lastly what you are trying to do probably would be easier with mplayer -noaudio -ao pcm:fast:file=halo.pcm or something like that.

I'm really surprised by this, but by using the svn version instead of git the problem went completely away. I'm going to try to make a test case for the git version and am in contact with some of the developers on IRC. Let me know if you want me to post the test case here.
