cordova-plugin-video-editor 用于本地壓縮視頻
Installation 安裝
cordova plugin add cordova-plugin-video-editor
this example uses the cordova media capture plugin
navigator.device.capture.captureVideo(
videoCaptureSuccess,
videoCaptureError,
{
limit: 1,
duration: 20
}
);
function videoCaptureSuccess(mediaFiles) {
// Wrap this below 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.
var file = mediaFiles[0];
var videoFileName = 'video-name-here'; // I suggest a uuid
VideoEditor.transcodeVideo(
videoTranscodeSuccess,
videoTranscodeError,
{
fileUri: file.fullPath,
outputFileName: videoFileName,
outputFileType: VideoEditorOptions.OutputFileType.MPEG4,
optimizeForNetworkUse: VideoEditorOptions.OptimizeForNetworkUse.YES,
saveToLibrary: true,
maintainAspectRatio: true,
width: 640,
height: 640,
videoBitrate: 1000000, // 1 megabit
audioChannels: 2,
audioSampleRate: 44100,
audioBitrate: 128000, // 128 kilobits
progress: function(info) {
console.log('transcodeVideo progress callback, info: ' + info);
}
}
);
}
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);
}
cordova-plugin-video-editor 源碼
npm i cordova-plugin-video-editor
我建議將 maintainAspectRatio 設(shè)置為 true。 如果此選項(xiàng)為真,則可以提供任何寬度 / 高度,并且提供的高度將用于計(jì)算輸出視頻的新寬度。 如果您將 maintainAspectRatio 設(shè)置為 false,那么您很有可能會得到拉伸和 / 或扭曲的視頻。 當(dāng) maintainAspectRatio 為 true-時(shí),下面是 iOS 上使用的簡化公式
aspectRatio = videoWidth / videoHeight;
outputWidth = height * aspectRatio;
outputHeight = outputWidth / aspectRatio;
默認(rèn)輸出路徑為: /storage/emulated/0/Movies/HelloCordova
cordova-plugin-zip 插件
https://www.npmjs.com/package/cordova-plugin-zip
cordova plugin add cordova-plugin-zip
壓縮包中的文件必須不包含中文名, 否則返回值為-1, 正確的是返回0
function unZip() {
var sourceZip = cordova.file.externalDataDirectory + 'abc.zip';
var destinationDir = cordova.file.externalDataDirectory + 'haha';
zip.unzip(sourceZip, destinationDir, function (result) {
// 0: OK -1: not OK
console.log(result);
},
function (progressEvent) {
progress = progressEvent.loaded / progressEvent.total;
console.log(progress);
});
}
cordova-plugin-dialogs 插件
navigator.notification.confirm
File 插件
可用于文件下載
function downloadFile() {
var url = 'https://upload-images.jianshu.io/upload_images/1662509-d5a04be8dd1167b4.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/1000/format/webp';
var path = cordova.file.externalDataDirectory + 'ddd.png';
var fileTransfer = new FileTransfer();
fileTransfer.download(url, path, function (entry) { console.log(entry) },
function (error) { console.log(error) }, true);
}
