Package Exports

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (decoding-info) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Decoding Info

Demo

This npm package allows you to determine the resolution of a supported video codec using the MediaCapabilities API.

Finding video codec resolution:

Minimum and maximum resolutions for a video codec.
Minimum and maximum resolutions for a video codec with smooth playback.
Minimum and maximum resolutions for a video codec in power-efficiency mode (similar to hardware acceleration).

Installation

npm install --save-dev decoding-info

Usage

import { getVideoCodecSupportedResolution } from 'decoding-info';

const configuration = {
    video: {
        codec: 'video/mp4; codecs="hvc1.1.6.L123.B0"',
        framerate: 25,
        bitrate: 1000000,
    },
};

getVideoCodecSupportedResolution(configuration).then((result) => {
    console.log(result);
    // {
    //     "error": null,
    //     "supported": {
    //         "value": true,
    //         "minHeight": 16,
    //         "minWidth": 16,
    //         "maxWidth": 8192,
    //         "maxHeight": 8192
    //     },
    //     "smooth": {
    //         "value": true,
    //         "minHeight": 16,
    //         "minWidth": 16,
    //         "maxWidth": 8192,
    //         "maxHeight": 8192
    //     },
    //     "powerEfficient": {
    //         "value": true,
    //         "minHeight": 16,
    //         "minWidth": 16,
    //         "maxWidth": 8192,
    //         "maxHeight": 8192
