Streaming WebM

[Teload]

I'm attempting to stream VP8 and Opus muxed into WebM using http. I'd like to be able to also use VBR for VP8 and Opus, but wasn't able to find how to do this in the Wiki. Thanks in advance!

Code: Select all

vlc $1 -I dummy --sout-keep \ vlc://quit --sout='#transcode{width=480,fps=15,vcodec=VP80,acodec=opus,channels=1}:std{access=http,mux=ffmpeg{mux=webm},dst=127.0.0.1:8000}'

Try a newer build. The 2.1 branch does not support Opus in WebM(MKV)
