ffmpeg でUstream.tv 配信

Posted at

ビデオソースをX のデスクトップにしてみている例.音声もあり.

$ ffmpeg -r 15 -s 800x600 -f x11grab -i :0.0 -f alsa -i default -acodec libmp3lame -vcodec libx264 -b 300k -ar 22050 -ab 48k -threads 4 -vsync 1 -y -f flv "rtmp://x.xxxxx.fme.ustream.tv/ustreamVideo/xxxx/xxxxxxxxxxxxx flashver=FME/3.020(compatible;20FMSc/1.0)"

RTMP のURL はダッシュボードから配信したい番組のリモート からRTMP URL とストリームキーを結合してつくる.
※Ustream.tv はffmpeg でデータを流し始めた後web管理画面で配信を行わな いといけない.
