splitting PID's from incoming UDP multicast stream

[hillya]

I have an incoming stream on udp 239.255.1.11:50111. It has three different programs on it, on PID's 49,65, and 81. I am trying to, using command line, ingest the stream, split out the pids, and output three different udp addresses, one for each pid. It is MPEG2 coming in, and I have no need to transcode. I

vlc -d -vvv udp://@224.1.1.3:1234 :sout=#duplicate{dst=udp{dst=224.1.1.4:1234}} :no-sout-rtp-sap :no-sout-standard-sap :ttl=8 :sout-keep

This works, but randomly chooses a program to output.

Any pointers would be appreciated.

Thanks!

I did get this working..

There are three programs running on a single incoming stream. I wanted to break them out into different channels into our lineup. Once I figured out the program numbers were 3, 4, and 5, here are the working commands:

vlc -d -vvv udp://@239.255.1.11:50111 :program=3 :sout=#duplicate{dst=udp{dst=224.1.3.10:8208}} :no-sout-rtp-sap :no-sout-standard-sap :ttl=8 :sout-keep

vlc -d -vvv udp://@239.255.1.11:50111 :program=4 :sout=#duplicate{dst=udp{dst=224.1.0.39:8208}} :no-sout-rtp-sap :no-sout-standard-sap :ttl=8 :sout-keep

vlc -d -vvv udp://@239.255.1.11:50111 :program=5 :sout=#duplicate{dst=udp{dst=224.1.0.53:8208}} :no-sout-rtp-sap :no-sout-standard-sap :ttl=8 :sout-keep

program #3 is an HD channel, and I was also able to transcode it to SD to add a 4th channel. I could not get this to work from command line, but here is the generated script when i went through the setup:

vlc -d -vvv udp://@239.255.1.11:50111 :program=3 :sout=#transcode{vcodec=mp2v,vb=6000,scale=1,width=720,height=480,acodec=mpga,ab=128,channels=2,samplerate=44100}:udp{mux=ts,dst=224.1.0.3:8208} :no-sout-rtp-sap :no-sout-standard-sap :ttl=8 :sout-keep

I hope someone finds this useful.

you may find this of use...

Code: Select all

--sout-all --http-caching=5000 :programs=261,517,773,1029 :sout=#duplicate{dst=std{access=http,mux=ts,dst=0.0.0.0:8080/p261},select="program=261",dst=std{access=http,mux=ts,dst=0.0.0.0:8080/p517},select="program=517",dst=std{access=http,mux=ts,dst=0.0.0.0:8080/p773},select="program=773",dst=std{access=http,mux=ts,dst=0.0.0.0:8080/p1029},select="program=1029"}

i use udp://224.2.2.2:1001 as my MPTS source....
