问题1：批量勾选相机拍摄的视频，官方API会出现勾选缺失的情况： { "tempFiles": [ { "height": 1280, "thumbTempFilePath": "wxfile://tmp_908a408fac8bfd8dcb20aadde9dd508d.jpg", "width": 720, "size": 121043, "duration": 1, "tempFilePath": "wxfile://tmp_0d6861e27473d9fc302ce45704d4fe85.mp4", "fileType": "video" }, { "height": 1280, "thumbTempFilePath": "wxfile://tmp_6323b4e0bbdd4bb263b7b041d1cbccf8.jpg", "width": 720, "size": 116056, "duration": 1, "tempFilePath": "wxfile://tmp_db65f17e1e9a1eeb1f7f85c8bc78f3f3.mp4", "fileType": "video" }, // 缺失了 { }, { "height": 1280, "thumbTempFilePath": "wxfile://tmp_e4020d23e8ba522a482e2c0aad17fce1.jpg", "width": 720, "size": 145337, "duration": 1, "tempFilePath": "wxfile://tmp_9e6fb0c223e056a6008e132f8e285ac6.mp4", "fileType": "video" } ], "errMsg": "chooseMedia:ok", "type": "video", "failedCount": 0 } 问题2： 当相册中含有微信聊天中保存的视频，勾选上传，无响应，也无发触发成功失败响应； 该视频在其它的微信小程序中测试，微信原生相册选择界面会出现无响应以及视频损坏提示； [图片] 问题3： 批量选择相册视频以及微信聊天保存视频，返回会出现几个视频失败； { "tempFiles": [ { "height": 960, "thumbTempFilePath": "wxfile://tmp_91e8dedf3a23cd502dd41af9f940cf6a.jpg", "width": 720, "size": 399609, "duration": 3, "tempFilePath": "wxfile://tmp_597f8fb5e6300f64ae8cdeaeaf9ee45b.mp4", "fileType": "video" }, { "height": 960, "thumbTempFilePath": "wxfile://tmp_1df6ea79eae1573da3b8823e410a684c.jpg", "width": 544, "size": 703200, "duration": 5, "tempFilePath": "wxfile://tmp_3fedbb4332a423e6f36dd5c7328104cd.mp4", "fileType": "video" }, { "height": 960, "thumbTempFilePath": "wxfile://tmp_ff778847b49896b6c30a133701c3a74c.jpg", "width": 720, "size": 180585, "duration": 2, "tempFilePath": "wxfile://tmp_94bc9a47c5420dc6d5b92ce5ce9e9a06.mp4", "fileType": "video" } ], "errMsg": "chooseMedia:ok", "type": "video", "failedCount": 5 } 问题4： 以上所说的视频选择”原图“上传，可以上传成功，点击预览视频无法播放；

chooseVideoFiles: function chooseVideoFiles() { return new Promise(function (resolve, reject) { wx.chooseMedia({ count: 9, mediaType: ['image', 'video'], sourceType: ['album', 'camera'], maxDuration: 50, camera: 'back', success: function success(res) { console.log(res); var videoFiles = res.tempFiles.map(function (file) { return file.tempFilePath; }); console.log(videoFiles); resolve(videoFiles); }, fail: function fail(err) 选择多个视频，只能成功一个 {"tempFiles": [{"height": 1280, "thumbTempFilePath": "wxfile://tmp_9bjpg", "width": 592, "size": 2254124, "duration": 17, "tempFilePath": "wxfile://tmp_6cbxxx.mp4", "fileType": "video"}], "errMsg": "chooseMedia:ok", "type": "video", "failedCount": 1}

微信小程序选择系统相册图片时可以滑动选择多张（微信聊天选择图片可以这样）？
