MediaEncodingConfiguration

MediaEncodingConfiguration dictionary of the 媒体能力 API is used to define the type of media being tested when calling MediaCapabilities.encodingInfo() to query whether a specific media configuration is supported, smooth, and/or power efficient.

特性

A MediaEncodingConfiguration dictionary takes two properties:

范例

//Create media configuration to be tested
const mediaConfig = {
    type : 'record', // or 'transmission'
    video : {
        contentType : "video/webm;codecs=vp8", // valid content type
        width : 800,     // width of the video
        height : 600,    // height of the video
        bitrate : 10000, // number of bits used to encode 1s of video
        framerate : 30   // number of frames making up that 1s.
     }
};
// check support and performance
navigator.mediaCapabilities.encodingInfo(mediaConfig).then(result => {
    console.log('This configuration is ' +  (result.supported ? '' : 'not ') + 'supported.')
});
