What sort of UDP do you need -- an RTP Transport Stream, an RTP Program Stream, a simple raw Transport stream, or what? Unless you're using a different `dvbstream' than I, it sends out RTP (partial or not) Transport Streams, with UDP packet size equal to the TS frame size (I hacked this to fill as much of an ethernet frame as possible). I don't know if your `szap2' program simply sets up the frontend to the desired frequency, or if it also sets hardware PID filters on your card -- I've always been able to use other utilities with bog-standard `t/szap' to work on the entire TS. If bandwidth is an issue, a HD H.264 stream is likely to weigh in around 10 to 20Mbit/sec; a full S2 transport stream is higher (DVB-S streams from Astra are on the order of 36Mbit/sec; S2 will likely be slightly more). Add the overhead for UDP encapsulation of the 188-byte packets, and I wouldn't be surprised if you push close to some hardware limits of a 100Mbit/sec network, given the unreliable nature of UDP, and that a single dropped or corrupt packet can appear as a video stream error. Although, as you said, your 'Doze works, so the sum of your hardware should be able to handle the traffic. Something I just learned a few seconds ago, dvbstream: -net ip:prt IP address:port combination to be followed by pids list. Can be repeated to generate multiple RTP streams This will filter your ~50Mbit/sec transponder down to a manageable size. Be sure to specify all the PIDs for ASTRA HD or whatever; for the DVB-S Eins Festival that will start tomorrow (Mo) with non-upscaled 720p content again, that should be 0 1600 -v 1601 -a 1602 1603 1606 (as arguments to standalone `dvbstream') Just some additional things to keep in mind... By the way, I also received some personal mail which I don't think made it to the list, and this may be of use to you, so I'll quote from that here, so that others may benefit: DUBOST Brice wrote: ``You can try mumudvb : http://mumudvb.braice.net, I think it will answer your needs'' thankz baz bouwsma _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
