[MPlayer-users] How to correct samplerate of mp3 stream in avi?

[rgselk]

Hi there,

I have an avi file with a mp3 stream which is claiming to have a
samplerate of 32kHz. However this should be 48kHz. The two bits in the
header indicating the frequency (bit 10,11) now read '10' and should
read '01'.
Is there a tool to modify this direct? Or else how do I know the offset
of this header, so I can write a small perl script to do the
manipulation.

Thanks,
  rgselk.
