[Freeswitch-users] Failing to execute OS Command

[Klaus Teller]

It seems there is really not much more. The ffmpeg command is invoked in the script after the caller hangup. So, most of the "cancel"  in the following logs are normal. The ffmpeg logs seem also eto be normal except the size of the output would be different is the conversion worked.

I initially thought the problem might be due to the fact that when ffmpeg was called freeswitch still had the lock on the generated wav file. This seems not to be the case. In another experiment, i copied the file to a temp file and tried to convert this temp file instead. The result was the same failed conversion.
