Hi to all and very compliments for your work, this software is wonderful.
I am sorry to trouble, i am used to search the forum to solve my problems but this time i have found no solutions...
I am trying to take an input. I have to transcode this input and to stream it over rtp. At the same time i want to transcode it (with different codecs) and to save it to a file.
I tried and tried more times with this example (2 files like output), but i don't understand what is the problem, it always says "invalid chain" (i use windows and vlc 0.8.4a):

Code: Select all

vlc.exe -vvv "C:\...\test.mpg" :sout=#duplicate{dst=transcode{vcodec=mp4v.....}:std{access=file,mux=mp4,url="C:/.../test1.mp4"},
dst=transcode{vcodec=mp4v....}:std{access=file,mux=mp4,url="C:/.../test2.mp4"}}

Input and output are corrects, they work if i try to stream (or save to a file) after a single transcoding... but not with multiple transcoding.
I tried with quotes, without quotes, i tried everything. What is wrong?
Hoping someone can help me... thank you so much, bye bye.

For example, my work vlm.conf

Code: Select all

new sat10-FM-EchoM-3 broadcast enabled
setup sat10-FM-EchoM-3 input "dvb:"
setup sat10-FM-EchoM-3 option dvb-frequency=3645000
setup sat10-FM-EchoM-3 option dvb-srate=28000000
setup sat10-FM-EchoM-3 option sout-standard-mux=ts
setup sat10-FM-EchoM-3 option sout-standard-access=udp
setup sat10-FM-EchoM-3 option sout-standard-sap
setup sat10-FM-EchoM-3 option programs=14
setup sat10-FM-EchoM-3 output #duplicate{dst=std{url=239.91.10.14,name=FM-EchoMoskow},select="es=403",
dst='transcode{acodec=mpga,ab=128}:std{url=239.92.11.141,name=L-FM-EchoMoskow}',select="es=403",
dst='transcode{acodec=mpga,ab=64}:std{url=239.92.11.142,name=LL-FM-EchoMoskow}',select="es=403"}

Hi, thank you very much for your help!! I think to have understood how i have to do... and it seems to work now.
My problem were i was not using VLM, but i thought it wasn't necessary... because i have just 1 input and 2 outputs... isn't it possibile to do that without vlm? Anyway it is just a curiosity, if someone can answer i am glad, otherwise the important thing is that it works.
So thanks very much again, now i am going to try something, and if i have other problems... you will hear from me.

Thanks again! Bye.
