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.

Joint source-channel coding/decoding (JSCC/JSCD) techniques have become state-of-the-art and one of the challenging research subjects in the spatial communication area. This paper addresses the ...

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.
