I’ve written about codecs in the past, and generally speaking, they more or less do the same job: compress and decompress video frames. And with new ones being created continually to address specific performance-related needs, it is not reasonable to definitively say “this one is best” without taking into account external factors like hardware, application needs, etc. Having said that, in the world of real-time media playback and video mixing, one codec in particular has caught on like wildfire since its creation in 2013; that codec is Hap.
