OBS Multiplatform is available as a package for several Linux distributions, and can be compiled from source.
Ubuntu 14.04/15.04+
14.04: FFmpeg is required.
If you do not have FFmpeg installed (if you're not sure, then you probably don't have it), you can get it with the following commands:
sudo add-apt-repository ppa:kirillshkrogalev/ffmpeg-next
sudo apt-get update && sudo apt-get install ffmpeg
14.04/15.04+: You can install OBS with the following commands:
sudo add-apt-repository ppa:obsproject/obs-studio
sudo apt-get update && sudo apt-get install obs-studio
好了，装上了。接下来可以在Ubuntu上搞直播了，以斗鱼为例。
在设置-串流填入相应地址即可。
