A web3 streaming platform delivers video through independent nodes and settles payments on a blockchain. How it differs from a CDN, and how AIOZ Stream does it.

WCAG video requirements: captions, audio description or a text alternative, and a keyboard-operable player. The 5 Level A and AA criteria, and what to check.

Import an existing HLS video into AIOZ Stream from its M3U8 master playlist URL. Every rendition is copied byte for byte, so nothing is re-encoded or changed.

Google indexes video content through VideoObject structured data, not by watching it. Map AIOZ Stream's API fields to the schema properties Google requires.

SDH subtitles add speaker names, sound effects and music cues to dialogue. See how SDH differs from closed captions and plain subtitles, and how to write it.

Rebuffering ratio is the share of watch time spent stalled; startup time is the wait for the first frame. Aim for under 1% rebuffering and a start within 2s.

WebRTC mesh vs SFU vs MCU: mesh links every caller directly and breaks past 4 people, an SFU forwards streams, an MCU mixes them. Costs and when to use each.

A CDN edge node caches video near your viewers so requests skip the origin. See how a video CDN, origin shielding, P2P CDNs and AIOZ DePIN delivery work.

MP4, MOV, WebM and MKV are video containers, not codecs. MP4 descends from MOV, WebM is a restricted MKV, and streaming players get none of them directly.

AV1 is a royalty-free codec that beats H.264 on compression. Netflix streams about 30% of its video in AV1, but encoding costs more and AIOZ Stream lacks it.

Widevine covers Chrome and Android, FairPlay covers Apple devices, and PlayReady covers Windows and Xbox. How their licenses, security tiers and cbcs differ.

Build a video analytics dashboard on three AIOZ Stream endpoints: aggregated, breakdown and timeseries. Watch time works on all three; retention needs two.
