The VideoConfiguration dictionary of the Media Capabilities API is used to define the video file being tested when calling the MediaCapabilities methods encodingInfo() and decodingInfo() to determine whether or not the described video configuration is supported, and how smoothly and how smoooth and power-efficient it can be handled.
Properties
The VideoConfiguration dictionary is made up of five video properties, including:
- contentType: A valid video MIME type. See our web video codec guide for types which may be supported.
- width: The width of the video.
- height: The height of the video.
- bitrate: The number of bits used to encode one second of the video file.
- framerate: The number of frames making up one second of video playback.
Examples
// Create media configuration to be tested
const mediaConfig = {
type : 'file', // see MediaDecodingConfiguration and MediaEncodingConfiguration
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.
}
