I am unable to capture some livestreams because of the proxy issues. So in rtmpdump i can use:
rtmpdump -v -r rtmp://a_rtmp_address -p http://a_http_address -S 85.185.244.101:1080 -B 10 -o aaa.flv
But I need to use ffmpeg or avconv. But I can not find a parameter corresponds to that -S 85.185.244.101:1080 parameter.
Can anyone please give me an ffmpeg command corresponding to this rtmpdump command.
