ist->frames_decoded is incremented after the call to this function, and 
in between, the fn returns if decode returned an error, so 
ist->frames_decoded shows the number of successfully decoded frames at 
the point of the result check and not the count of total packets/frames 
sent for decoding upto that point. Is that the intention?
