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.
