Looks to have a similar functionality as "obs-studio" i.e is streaming focused, where screenstudio looks to be more like "vokoscreen" with some extra options. Like all the others it runs using "ffmpeg" except that this one needs a java layer to execute where obs-studio is python based IIRC.
I have no experience whatsoever in creating streaming content other than [live]streaming through vlc.
So: If it isn't a too big bother, would you care to compare both to one another?
You know, just give some pros and cons in respect to ease of use, stability and hardware usage....that would be great.
