Hi all

I have my personal computer with a webcam that sends one stream to a dedicated (company) server that I would like to stream in multiple qualities - like 256 kbps and 128 kbps.

I can only have one of the channels working at the time - here the channel "webtv2" (on port 9001) which seems to override the webtv1-settings.

Code: Select all


# VLC media player VLM command batch
# http://www.videolan.org/vlc/

new webtv1 broadcast enabled loop
setup webtv1 input "udp://@:8080"
setup webtv1 output #transcode{vcodec=WMV2,vb=256,scale=1,acodec=mp3,ab=128,channels=1}:duplicate{dst=std{access=mmsh,mux=mpeg1,dst=:9000}}

control webtv1 play

new webtv2 broadcast enabled loop
setup webtv2 input "udp://@:8080"
setup webtv2 output #transcode{vcodec=WMV2,vb=128,scale=1,acodec=mp3,ab=128,channels=1}:duplicate{dst=std{access=mmsh,mux=mpeg1,dst=:9001}}

control webtv2 play

I think that you can only have a one / unique input for each channel, is this correct? And if so what workarounds can be applied?

You should have a look at the #duplicate sout thing in http://www.videolan.org/doc/ streaming howto chapter 03.

Hi Dionoea

Thank you for your answer.

But if I use the dubplicate-thing I can only have another setting for access, mux'er and destination and not the bitrate for vb and ab. In orther words I can stream to another server with another mux'er, but it is still in the same encoders and bitrate (and I like it to be in another bitrate, so people with bad internet-connections also have a chance to see the stream - in a lower quality).

Can you cast any light on this subject?

you can do this:

Code: Select all

--sout "#duplicate{dst='transcode{vcodec=mp2V,vb=2048}:std{access=udp,mux=ts,dst=239.255.1.1}',dst='transcode{vcodec=DIV3,vb=512,scale=0.5}:std{access=mmsh,mux=asfh,dst=0.0.0.0:8080}'}"

Each dst=' ... ' is exactly like a complete sout chain.
