Firefox中的WebM/VP9支持 [英] WebM/VP9 support in Firefox

问题描述

据我了解，Firefox和Chrome支持WebM/VP9已有一段时间了.

As far as I understand, WebM/VP9 has been supported by both Firefox and Chrome for quite a while.

但是，在我的机器上，MediaRecorder.isTypeSupported('video/webm; codecs = vp9')在Firefox中返回 false ，但在Chrome中返回 true .

However, on my machine MediaRecorder.isTypeSupported('video/webm;codecs=vp9') returns false in Firefox, but true in Chrome.

软件:Firefox 81.0，Chrome 85，MacOS 10.15.MacBook Pro i72016.可能与硬件相关吗?

Software: Firefox 81.0, Chrome 85, MacOS 10.15. MacBook Pro i7 2016. Could it be hardware related?

推荐答案

研究了Firefox代码后，我发现截至目前，FireFox MediaRecorder不支持WebM/VP9.我查看的源代码位于 MediaRecorder.cpp

After looking into Firefox code, I found out that as of today FireFox MediaRecorder does not support WebM/VP9. The source code I looked at is here MediaRecorder.cpp

含义是什么?使用MediaRecorder在 Chrome 5-10Mb(WebM/VP9)，在 Firefox 40-50Mb(WebM/VP8)上录制的60秒视频).

The implications? 60 second video recorded with MediaRecorder on Chrome 5-10Mb (WebM/VP9), on Firefox 40-50Mb (WebM/VP8).
