为何 AV1 仍未普及?
#商业

AV1 是 AOMedia 在 2018 年释出的开源免专利费编解码器,其压缩效率比 H.265(HEVC) 提升了三成。AOMedia 的成员包括了 Netflix、微软、Google、亚马逊和 Meta 等巨头。然而七年之后,尽管免专利费且有科技巨头们的支持,AV1 仍然未普及,流行的流媒体应用如 Max、Peacock 和 Paramount Plus 仍然没有采用 AV1。背后的一大原因是 AV1 需要硬件支持,它的软解码方案存在严重缺陷,如 VideoLAN 开发的 AV1 解码器 dav1d 会严重影响手机的续航力。目前 Netflix 约 95% 的内容用 AV1 编码,而 YouTube 视频的 AV1 编码比例是 50%。AV1 目前还面临 MPEG 和 VCEG 开发的 VVC(H.266)方案的竞争,VVC 的压缩效率提升了五成,但不是免专利费。
theverge:AV1 is supposed to make streaming better, so why isn’t everyone using it?

For some time, Mr. Durov and a few dozen staffers had no fixed headquarters, but rather traveled the world, setting up shop in one city after another, he told the Journal in 2016. The company now has its operational base in Dubai, though it says it doesn’t keep servers there.Mr. Durov maintains a yearslong friendship from his VK days with actor and tech investor Jared Leto, with whom he shares an ascetic lifestyle that eschews meat and alcohol.

Mr. Durov launched Telegram in late 2013 with his brother, Nikolai, just months before he was pushed out of VK, the Russian social-media platform he founded. Mr. Durov pitched his new app—funded with the proceeds from the VK sale—less as a business than as a way for people to send messages while avoiding government surveillance and censorship.
