The End of Video Coding?

An anonymous reader writes: Netflix’s engineering team has an insightful post today that looks at how the industry is handling video coding; the differences in their methodologies; and the challenges new comers face. An excerpt, which sums up where we are: “MPEG-2, VC1, H.263, H.264/AVC, H.265/HEVC, VP9, AV1 — all of these standards were built on the block-based hybrid video coding structure. Attempts to veer away from this traditional model have been unsuccessful. In some cases (say, distributed video coding), it was because the technology was impractical for the prevalent use case. In most other cases, however, it is likely that not enough resources were invested in the new technology to allow for maturity. “Unfortunately, new techniques are evaluated against the state-of-the-art codec, for which the coding tools have been refined from decades of investment. It is then easy to drop the new technology as “not at-par.” Are we missing on better, more effective techniques by not allowing new tools to mature? How many redundant bits can we squeeze out if we simply stay on the paved path and iterate on the same set of encoding tools?”
