How can I set preview of video file, selecting from input type='file'
JavascriptJqueryHtmlVideoHtml5 VideoJavascript Problem Overview
In one of my module, I need to browse video from input[type='file'], after that I need to show selected video before starting upload.
I am using basic HTML tag to show. but it is not working.
Here is code:
$(document).on("change",".file_multi_video",function(evt){
var this_ = $(this).parent();
var dataid = $(this).attr('data-id');
var files = !!this.files ? this.files : [];
if (!files.length || !window.FileReader) return;
if (/^video/.test( files[0].type)){ // only video file
var reader = new FileReader(); // instance of the FileReader
reader.readAsDataURL(files[0]); // read the local file
reader.onloadend = function(){ // set video data as background of div
var video = document.getElementById('video_here');
video.src = this.result;
}
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<video width="400" controls >
<source src="mov_bbb.mp4" id="video_here">
Your browser does not support HTML5 video.
</video>
<input type="file" name="file[]" class="file_multi_video" accept="video/*">

Solution 1 - Javascript
@FabianQuiroga is right that you should better use createObjectURL
than a FileReader
in this case, but your problem has more to do with the fact that you set the src of a <source>
element, so you need to call videoElement.load()
.
$(document).on("change", ".file_multi_video", function(evt) {
var $source = $('#video_here');
$source[0].src = URL.createObjectURL(this.files[0]);
$source.parent()[0].load();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<video width="400" controls>
<source src="mov_bbb.mp4" id="video_here">
Your browser does not support HTML5 video.
</video>
<input type="file" name="file[]" class="file_multi_video" accept="video/*">
Ps: don't forget to call URL.revokeObjectURL($source[0].src)
when you don't need it anymore.
Solution 2 - Javascript
Do not forget that it uses jquery library
Javascript
$ ("#video_p").change(function () {
var fileInput = document.getElementById('video_p');
var fileUrl = window.URL.createObjectURL(fileInput.files[0]);
$(".video").attr("src", fileUrl);
});
Html
< video controls class="video" >
< /video >

If you are facing this issue. Then you can use the below method to resolve the above issue.
Here is the html code:
//input tag to upload file
<input class="upload-video-file" type='file' name="file"/>
//div for video's preview
<div style="display: none;" class='video-prev' class="pull-right">
<video height="200" width="300" class="video-preview" controls="controls"/>
</div>
Here is the JS function below:
$(function() {
$('.upload-video-file').on('change', function(){
if (isVideo($(this).val())){
$('.video-preview').attr('src', URL.createObjectURL(this.files[0]));
$('.video-prev').show();
}
else
{
$('.upload-video-file').val('');
$('.video-prev').hide();
alert("Only video files are allowed to upload.")
}
});
});
// If user tries to upload videos other than these extension , it will throw error.
function isVideo(filename) {
var ext = getExtension(filename);
switch (ext.toLowerCase()) {
case 'm4v':
case 'avi':
case 'mp4':
case 'mov':
case 'mpg':
case 'mpeg':
// etc
return true;
}
return false;
}
function getExtension(filename) {
var parts = filename.split('.');
return parts[parts.length - 1];
}
Solution 4 - Javascript
Lets make it easy
HTML:
<video width="100%" controls class="myvideo" style="height:100%">
<source src="mov_bbb.mp4" id="video_here">
Your browser does not support HTML5 video.
</video>
JS:
function readVideo(input) {
if (input.files && input.files[0]) {
var reader = new FileReader();
reader.onload = function(e) {
$('.myvideo').attr('src', e.target.result);
};
reader.readAsDataURL(input.files[0]);
}
}
Solution 5 - Javascript
Here is an easy peasy solution
document.getElementById("videoUpload").onchange = function(event) {
let file = event.target.files[0];
let blobURL = URL.createObjectURL(file);
document.querySelector("video").style.display = 'block';
document.querySelector("video").src = blobURL;
}
<input type='file' id='videoUpload'/>
<video width="320" height="240" style="display:none" controls autoplay>
Your browser does not support the video tag.
</video>
the solution is using vanilla js so you don't need JQuery with it, tested and works on chrome, Goodluck
Solution 6 - Javascript
This is example on VUE JS: preview PICTURE
Example SOURCE CODE - DRAG-DROP _part
Example with RENDERing & createObjectURL() using VIDEO.js
p.s. i just want to improve "Pragya Sriharsh" solution:
const = isVideo = filename =>'m4v,avi,mpg,mov,mpg,mpeg'
.split(',')
.includes( getExtension(filename).toLowerCase() )
And .. please don't use JQuery, it's now 2k19:-);
-> So:
const getExtension = filename => {
const parts = filename.split('.');
return parts[parts.length - 1];
}
... And let the rest of the work will be done by Webpack 4!
