Seeing as OBS is now ubiquitous for livestreaming, I have to wonder if there's one or more software companies out there who see all that usage as lost revenue from a proprietary solution and are kicking themselves over it.
I almost can't believe how good OBS is for being open source.
Wirecast has been around since the mid-2000s and has a very similar feature set to OBS. It is lacking in some areas and ahead of the curve in others (Wirecast has GPU-accelerated scene preview thumbnails instead of OBS’ flat text list). VMix is another successful proprietary desktop streaming software. You could also probably add the OG, TriCaster, to the same list as it solves many of the same problems (video switching on commodity PC hardware, real-time layering/compositing, desktop capture, etc) but is married to NewTek’s hardware.
