Netflix AV1

Il 30% dello streaming Netflix è in AV1. Prima Android (2020):

When we first set out to bring AV1 streaming to Netflix members, Android was the ideal starting point. Android’s flexibility allowed us to quickly integrate a software AV1 decoder using the efficient dav1d library, which was already optimized for ARM chipsets in mobile devices.

Poi TV e roba Apple:

Smart TVs depend on hardware decoders for efficient high-quality playback. We worked closely with device manufacturers and SoC vendors to certify these devices, ensuring they are both conformant and performant. This collaborative effort enabled our AV1 streaming to TV devices in late 2021. Shortly thereafter, we expanded AV1 streaming to web browsers (in 2022) and continued to broaden device support. In 2023, this included Apple devices with the introduction of AV1 hardware support in the new M3 and A17 Pro chips.

Nei browser il 40% degli stream sono con dav1d.

Video.js 10

Nel 2026 uscirà Video.js 10, nuova versione dell'ultrapopolare player video JavaScript. Sarà essenzialmente riprogettato fondendo concetti di Plyr, Media Chrome e Vidstack per renderlo compatibile con lo sviluppo moderno a componenti/React.

Ho sempre trovato scomodi i player video che quando sono in pausa o quando mostrano i controlli di riproduzione coprono o rendono più scuro il video. Si è unito Safari su macOS 26:

Safari darkens videos on iOS 18, iOS 26, and now macOS 26 when its native video controls are displayed. If you wait several seconds for the video controls to disappear, or you move your Mac mouse pointer out of the frame, the video returns to its normal level of lightness.

Seriously, why??? I thought Liquid Glass was supposed to “bring greater focus to content”? Darkening videos brings less focus to content!
