Hello There,

I would like to stream 4 cams to YouTube using ffmpeg.

I was able to get 2 to work as follows:

ffmpeg -rtsp_transport tcp
-i "rtsp://xxxx:xxxx@10.1.10.125:554/cam/realmonitor?channel=1&subtype=0"
-i "rtsp://xxxx:xxxx@10.1.10.125:554/cam/realmonitor?channel=2&subtype=0"
-f lavfi -i anullsrc
-filter_complex "
[0:v] setpts=PTS-STARTPTS, scale=800x448,setsar=1[upperleft];
[1:v] setpts=PTS-STARTPTS, scale=800x448,setsar=1[upperright];
[upperleft][upperright]hstack[base]"
-map [base] -map 2 -f flv rtmp://
x.rtmp.youtube.com/live2/xxxx:xxxx-xxxx:xxxx

But how do I add two more below those two?

You can view the two here:
