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

Dear Jean,

Thank you so much for reply my message. 

I am sorry the function return 38 is speex_bits_write(). This function
doesn't work on one of my computers. But after I add the function
speex_preprocess(), it works well. I am wondering what is the possible reason?
What the function speex_preprocess() does?

Another problem I have now is when I enable dtx and vad with function
speex_preprocess(). The sound disappeared after I decode it. What shall I do?

Thanks

Jonathan

Actually, 38 is normal for the 15 kbps mode. For the rest, could you
give more details. Also, what platform is the problematic machine? (What
CPU, what OS, what compiler).

What do you mean exactly?
