In rm_read_audio_stream_info():

            if(sub_packet_size <= 0){
                av_log(s, AV_LOG_ERROR, "sub_packet_size is invalid\n");
                return -1;

I assume you removed that check and didn't send a patch for it (or did
I miss it?)?

In any case, I've seen the samples and thanks for looking at it, I was
intending to do that at some point. :-).
