I have to play video in my website. The video is uploaded via multer with node.js and in express framework.The file is inserting to the database and the specified folder(file name like 1b47c24b20cc2465fbcb395fd1a9dfb4). I am uploading image also and its showing properly But video is not playing.

Here is my html code

<div class="form-group">
<label>Upload image</label>
<input type="file" name="file" id="file" ng-model="testimonial.file" ngf-select ngf-max-size="25MB" required">
<img ng-src="/images/" width="49" height="49" ng-model="testimonial.file" /><br/>
<label>Upload video</label>
<input type="file" name="video" id="video" ng-model="testimonial.video" ngf-select ngf-max-size="25MB" required">
<video width="320" height="240" controls>
<source src="/images/" type="video/mp4">
<source src="movie.ogg" type="video/ogg">
Your browser does not support the video tag.
</video>
</div>
