    Thanks for that screenshot, Very interesting to see, that also on the other side of the globe, Multistream is in use.

    Is it the only mux over there?

    Hey Peon,


    that sounds really intersting. Which manufacturer produced your antena?

    It's a segment dish, so is ku-band reception also efficient?

    I always wondered why there are no more Fibo/Gregorian antenas on the market any more.

    The method is called MPE. Linux even offers a virtual network interface. You can analyze the stream with wireshark or tcpdump or open up multicast addresses via vlc.


    The package dvb-tools contains a util called dvbnet, it supports MPE oder ULE (with the -U argument) however so far I didn't see any ULE stream. Dvbsnoop is also useful for checking which ip addresses and ports are used


    First you need to set up dvbnet to listen on the pid. then you need to set hw ether address and Ip address for the created virtual interface and enable it. You need to call this command twice, first call will give an error. Here is an example for pid 101:

    dvbnet -p 101


    ifconfig dvb0_0 192.168.238.238 hw ether 00:01:02:03:04:05 promisc up


    ifconfig dvb0_0 192.168.238.238 hw ether 00:01:02:03:04:05 promisc up


    route add -net 224.0.0.0 netmask 240.0.0.0 dev dvb0_0


    echo 0 > /proc/sys/net/ipv4/conf/all/rp_filter


    echo 0 > /proc/sys/net/ipv4/conf/dvb0_0/rp_filter


    For closing you need to set the interface down before you can remove it.


    ifconfig dvb0_0 down

    dvbnet -d 0


    Interneting streams for us use a multicast ipaddress, that means first octet is between 224-239

    I've also seen MPE streams were the source and not the destination ip is multicast.

    You could try to set the interface to the unicast destination ip and listen to this ip via vlc then.

    two stream in one TS


    Finally I'm able to deprocess this stream using a DigitalDevices CineS2 V7a.


    It's GSE with 2 UDP multicast streams. These streams contain a TS each. One is skytg24, the other one was a Testcard when I checked last time.
    I will publish a GSE decoder when I finished it, ATM only a sunset is implemented to decode this mux.
    If you know more streams like this please tell me.

    I guess you have to record the mxf file from.the beginning. Unlike TS where header information is repeated regularly, this is not the case for mxf.


    Do you know other mxf feeds as well?

    There is one big MPE mux with multiple DAB EDI streams on Eutelsat 7°E containing 5 BR muxes plus SWR S mux.


    In linux we are already able to decode those muxes using Piratfm's tool https://github.com/piratfm/eti-tools


    There's also a list of already found DAB distribution feeds.
    I guess there are more around, but finding them needs analysis with Hex Editor.


    EnoSat: Did you try IPCleaner.exe for Mxf?

    Hi newsy,


    okay, checked complete spectrum right now, but there are no other PLS muxes on - in my opinion (11491 V PLS known).


    :117:


    Thanks for checking. However today I can't get a lock with my 120cm dish on 11496 H.
    Perhaps they already changed PLS key again.


    The PLS key is still valid for 11491 V, however crazyscan has a little bug when entering PLS key manually for transponders that don't use MIS.


    I you go back to 2380 and then do bruteforce you should get a lock with 2388.
