This is a cordova plugin to assist in several video editing tasks such as:
npm install cordova-plugin-video-editor-forkThis is a cordova plugin to assist in several video editing tasks such as:
* Transcoding
* Trimming
* Taking still images from time moments (currently the start of a video)
After looking at an article on How Vine Satisfied Its Need for Speed, it was clear Cordova/Phonegap needed a way to modify videos to be faster for app's that need that speed.
This plugin will address those concerns, hopefully.
cordova plugin add https://github.com/jbavari/cordova-plugin-video-editor.git
and VideoEditorOptions will be available in the window after deviceready.Usage
###Transcode###
`javascript
// parameters passed to transcodeVideo
VideoEditor.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
quality: VideoEditorOptions.Quality.MEDIUM_QUALITY,
outputFileType: VideoEditorOptions.OutputFileType.MPEG4,
optimizeForNetworkUse: VideoEditorOptions.OptimizeForNetworkUse.YES,
duration: 20, // optional, specify duration in seconds from start of video
saveToLibrary: true // optional, defaults to true
}
)
`
javascript
// options used with transcodeVideo function
var VideoEditorOptions = {
Quality: {
HIGH_QUALITY: 0,
MEDIUM_QUALITY: 1,
LOW_QUALITY: 2
},
OptimizeForNetworkUse: {
NO: 0,
YES: 1
},
OutputFileType: {
M4V: 0,
MPEG4: 1,
M4A: 2,
QUICK_TIME: 3
}
};
`
javascript
// this example uses the cordova media capture plugin
navigator.device.capture.captureVideo(
videoCaptureSuccess,
videoCaptureError,
{
limit: 1,
duration: 20
}
);function videoCaptureSuccess(mediaFiles) {
var file = mediaFiles[0];
var videoFileName = 'video-name-here'; // I suggest a uuid
// Wrap this call in a ~100 ms timeout on Android if
// you just recorded the video using the capture plugin.
// For some reason it is not available immediately in the file system.
VideoEditor.transcodeVideo(
videoTranscodeSuccess,
videoTranscodeError,
{
fileUri: file.fullPath,
outputFileName: videoFileName,
quality: VideoEditorOptions.Quality.MEDIUM_QUALITY,
outputFileType: VideoEditorOptions.OutputFileType.MPEG4,
optimizeForNetworkUse: VideoEditorOptions.OptimizeForNetworkUse.YES,
duration: 20
}
);
}
function videoTranscodeSuccess(result) {
// result is the path to the transcoded video on the device
console.log('videoTranscodeSuccess, result: ' + result);
}
function videoTranscodeError(err) {
console.log('videoTranscodeError, err: ' + err);
}
