I have a test I'm trying to perform using command-line VLC that I'm befuddled by - I've scoured this site and others looking for a solution but I've found nothing so far. Here is my issue (FYI, I posted an issue similar to this last week, but due to my lack of knowledge it was vague and I was making several bad assumptions, so I'm creating a new topic now that I know exactly what I need to do). I need to:
1. Take a screen capture, encode it into mp4, and send it along to a multicast IP address, like so:
Code: Select all
start vlc screen:// screen-fps=15 :file-caching=0 --screen-width=640 --screen-height=480 --screen-top=0 --screen-left=0 :sout=#transcode{vcodec=mp4v,vb=3500}:duplicate{dst=rtp{dst=239.1.1.1,mux=ts,port=7100}} :sout-all :sout-keepCode: Select all
cvlc rtp://@239.1.1.1:7100 :sout=#transcode{venc=x264,vcodec=h264,scale=0.5}:duplicate{dst=rtp{dst=239.2.1.1,mux=ts,port=7100}} :sout-all :sout-keepCode: Select all
vlc -vvv rtp://239.2.1.1:7100 :sout=#duplicate{dst=rtp{dst=display} :sout-all :sout-keepCode: Select all
