When I upload upload video, I need video duration, How I can get it

Hi @freelanceromarr ,

here's what I use, I don't know if it will help.

I have a method for the @select event, and in that function, I try to use HTML to open the video file and get the metadata.
I think it works everytime so far.

<vue-file-agent ref="fileUpload"
                         @select="filesSelected($event)" />

setFileInfo(file) {
            let myVideos = [ file.file ];
            var video = document.createElement('video');
            video.preload = 'metadata';
            video.onloadedmetadata = function() {
                window.URL.revokeObjectURL(video.src);
                var duration = video.duration;
                file.duration = duration;
            }
            video.src = URL.createObjectURL(file.file);
        },
        async filesSelected(fileRecordsNewlySelected) {
    
            var validFileRecords = fileRecordsNewlySelected.filter((fileRecord) => !fileRecord.error);
            
                for (let index = 0; index < validFileRecords.length; index++) {
                    const validFile = validFileRecords[index];
                    const fileName = validFile.name()
                    this.setFileInfo(validFile)

                }
