Apple finally shot! Perfect elimination H.265/264 video decoding is true

Unfortunately, on Apple's latest processor chip M2, the AV1 format video decoding is still not supported, or the 8K H.264 (AVC) and H.265 (HEVC) of the old set & rdquo; H.265 (HEVC).

I am afraid that I still remember that Apple has not joined the Alliance for Open Media (AOM) as early as 4 years ago, and how to move is still so slow?

The specific reasons are not easy to analyze, but the good news is that the new global variable column KCMVideocodectype_av1 appeared in the core media framework library contributed by Apple. The major supplement can be regarded as a substantial progress towards the AV1 format.


It is reported that,Compared with H.264/265 or even VP9, AV1 has the characteristics of open source and copyright exemption. At the same time, the greater advantage is that it can provide higher compression rates under the same picture quality than H.265/264/VP9 You can transmit more high -definition image quality.

At present, the 11/12 generation Core, AMD, and NVIDIA graphics cards have supported the AV1 format decoding, and Intel ARC's independent display is the first to support hardware -level codecs. In terms of software, Google Chrome browser and iQiyi website have supported AV1 formats.
