Base64 relies on simple encoding and decoding algorithms. They work with a 65-character subset of US-ASCII where each of the first 64 characters maps to an equivalent 6-bit binary sequence.

That’s particularly true for encoding and decoding. “We really drive home the point that [decoding and encoding] are reciprocal, and they bootstrap each other,” Gillis said.

It's just announced that Vulkan Video, a low-level API for handling video streams, now fully supports the hardware acceleration of the H.264 and H.265 standards for decoding and encoding.
