我尝试使用 vlc 将台式机电视卡的输出传输到笔记本电脑，但没有成功。我在两台电脑上都安装了 ArchLinux。
我被困在这里：
$ cvlc v4l2:///dev/video0:norm=pal-nc:frequency=543250:size=640x480:channel=0:input-slave=alsa:///dev/dsp:audio=0 --sout '#transcode{vcodec=mp4v,acodec=mpga,vb=3000,ab=256,vt=800000,keyint=80,deinterlace}:standard{access=http,mux=ogg,dst=192.168.0.2:8080}' --ttl 12

知道为什么这不起作用吗？
答案1
mux=ogg 用于 vcodec=theora，也许是 mux=ts？
您是否有其他软件在监听 8080 端口？192.168.0.2 是您用于 cvlc 流式传输的机器的地址吗？
