I have download one sample from osmocom speech codec http://tetra.osmocom.org/trac/wiki/Speech_Codec. I  have compiled it sucesssfully then the output "ccoder.exe"

 and "cdecoder.exe" have been built. When i try to run the sample exe file using the command line, it show Segmentation fault (core dumped).

This is the how i'm running the sample

"./ccoder.exe sample.wav sample2.wav".

I'm very confusing about the input and the output file. What is the correct type file for input and the output.

Thank you for any respond
