They're not licensing codecs, they're licensing different versions of their software. The HEVC fee is only 20 cents per encoder, but I'll guess those video software options are thousands of dollars each.
While HEVC fees are only a tiny fraction of their encoders, they are far greater than 20 cents. Adding two of the pools together already nets up to $1.40, and there are more pools with unannounced pricing yet. https://en.wikipedia.org/wiki/High_Efficiency_Video_Coding#P...
