Answer 1

组合命令:

ffmpeg -i http://10.10.10.3:9981/stream/channelnumber/9 -i http://10.10.10.3:9981/stream/channelnumber/15 -map 0 -c copy -f mpegts "udp://224.2.2.119:2001?pkt_size=188&localaddr=192.168.2.119" -map 1 -c copy -f mpegts "udp://224.2.2.120:2002?pkt_size=188&localaddr=192.168.2.119"

不要使用 -re 用于实时输入流。
