Speex dev - Aug 2004 - DTX and VAD doesn't work on one of my computers.

Hi there,

I enable DTX and VAD in speex_encode to detect whether there is silence in voice
data. But the same programme got different result on my computers. The function
speex_encode always return 38 on one of my computers although it is silence. On
all other computers the function speex_encode return 1 when it is silence. It
means DTX and VAD doesn't work on particular OS or PC. Do anyone have some
idea what is the reason?

Thanks
Jonathan

This seems to indicate that speex_encode never detects silence, which is
possible because its VAD is pretty simple (might want to try the one in
the preprocessor). As for the return value, though 1 and 38 will be
interpreted the same (TRUE), I really don't see how you can get 38 since
the code only contains "return 0" and "return 1". Might want
to check
your compiler more closely.
