I think i would need your help in this. I am facing issues while trying to
play .g729 file (I pasted function definition below). Looks like line
"file_def->getFileInstance(RTPStream()->getPayloadType());" returns null
value. I made sure g729 file is there in the path (For test I am using a
asterisk demo file). It also crashes after showing error.. This is what my
debug output is..
