this file has 3 streams marked, Video/Audio and Dvb Subtitles. problem is that there are no subtitles being sent at the time. If you follow my previous message you will see if you add  -scodec dvbsub you get encoding but no time and no bitrate update, also the output especially to udp is done in blocks with large gaps

thanks for the quick reply
