This is a cordova plugin to assist in several video editing tasks such as:

• Transcoding
• Trimming
• Creating thumbnails from a video file with specific time in the video
• Getting info on a video - width, height, orientation, duration, size, & bitrate.

This plugin will address those concerns, hopefully.

Installation

cordova plugin add cordova-plugin-video-helper

VideoHelper will be available in the window after deviceready.

Usage

Transcode a video

// parameters passed to transcodeVideo
window.VideoHelper.transcodeVideo(
    success, // success cb
    error, // error cb
    {
        fileUri: 'file-uri-here', // the path to the video on the device
        outputFileName: 'output-name', // the file name for the transcoded video
        width: 340, // optional, see note below on width and height
        height: 640, // optional, see notes below on width and height
        videoBitrate: 5000000, // optional, bitrate in bits, defaults to 5 megabit (5000000),
        duration: 60, // optinal for triming while compressing
        type: 'ffmpeg' // optinal default for ffmpeg. You can use MediaCoder for compress(Only android)
    }
);

transcodeVideo example -

// this example uses the cordova media capture plugin
window.device.capture.captureVideo(
    videoCaptureSuccess,
    videoCaptureError,
    {
        limit: 1,
        duration: 20
    }
);

function videoCaptureSuccess(mediaFiles) {
    var outputFileName = (
        new Date().getTime()
    ).toString() + (
        outputFileName ? outputFileName : this.getFileNameFromURL(fileUrl)
    );
    const mediaSizeResult: {
        error: boolean,
        data: { bitrate: string, duration: string, height: string, orientation: string, size: number, width: string }
    } = this.getVideoInformation(fileUrl);

    const originalSize = Math.floor(+mediaSizeResult.data.size / 1024) / 1000 + 'MB';
    const originalBitrate = +mediaSizeResult.data.bitrate;

            (error) => {

                return resolve({error: true, data: null});

    } else if (split.length > 0) {
        fileName = split[0];
    }
    return fileName;
}

Trim a Video

VideoHelper.trim(
    {
        fileUri: 'file-uri-here', // path to input video
        duration: 15, // time to end trimming in seconds
        outputFileName: 'output-name', // output file name
    },
    trimSuccess,
    trimFail,
);

function trimSuccess(result) {
    // result is the path to the trimmed video on the device
    console.log('trimSuccess, result: ' + result);
}

function trimFail(err) {
    console.log('trimFail, err: ' + err);
}

Create a JPEG thumbnail from a video

VideoHelper.createThumbnail(
    {
        fileUri: 'file-uri-here', // the path to the video on the device
        outputFileName: 'output-name', // the file name for the JPEG image
        atTime: 2, // optional, location in the video to create the thumbnail (in seconds)
        width: 320, // optional, width of the thumbnail
        height: 480, // optional, height of the thumbnail
    },
    success, // success cb
    error, // error cb
);
// atTime will default to 0 if not provided
// width and height will be the same as the video input if they are not provided
// quality will default to 100 if not provided

A note on width and height used by createThumbnail

The aspect ratio of the thumbnail created will match that of the video input. This means you may not get exactly the width and height dimensions you give to createThumbnail for the jpeg. This for your convenience but let us know if it is a problem.

Get info on a video (width, height, orientation, duration, size, & bitrate)

VideoHelper.getVideoInfo(
    success, // success cb
    error, // error cb
    {
        fileUri: 'file-uri-here', // the path to the video on the device
    }
);

VideoHelper.getVideoInfo(
    getVideoInfoSuccess,
    getVideoInfoError,
    {
        fileUri: file.fullPath
    }
);

function getVideoInfoSuccess(info) {
    console.log('getVideoInfoSuccess, info: ' + JSON.stringify(info, null, 2));
    {
        /*
        width: 1920,
        height:1080,
        orientation:'landscape', // will be portrait or landscape
        duration:3.541, // duration in seconds
        size:6830126, // size of the video in bytes
        bitrate:15429777 // bitrate of the video in bits per second,
        videoMediaType: 'video/3gpp' // Media type of the video, android example: 'video/3gpp', ios example: 'avc1',
        audioMediaType: 'audio/mp4a-latm' // Media type of the audio track in video, android example: 'audio/mp4a-latm', ios example: 'aac',
         */
    }
