SFU

VP8

  • こっちのほうが古い
  • It can work well at lower bitrates and is a mature video codec in the context of WebRTC
  • iOS 12.2+.

H.264

  • H.264 may not perform as well at lower bit-rates when compared to VP8.
  • H.264 is not well suited to large sessions since it does not support the OpenTok Scalable Video? feature.
  • Chrome on Android only supports H.264 on devices that contain the Qualcomm and Exynos chipsets and require Google Chrome 65? or higher

メモ

  • Non-Safari browsers running in iOS (for example, Chrome and Firefox) use a Safari webview under the hood. The Safari webview does not support WebRTC and the OpenTok SDK.

問題

  • VP8 works on all Android devices.
  • older versions of Safari do not have VP8 codec support.
