As part of Intel’s Scalable Video Technology (SVT) initiative they had been developing SVT-HEVC as a BSD-licensed high performance H.265/HEVC video encoder optimized for Xeon Scalable and Xeon D processors. But recently they’ve changed course and the project has been officially discontinued.
I do think they’re on a decline, but enterprise moves SLOW and that’s big money. ARM is going places, but the x86 market could almost just freeze entirely and still be worthwhile for legacy applications for a very long time.
