It is enough to define the image URL for the
logocontrolbaroption. If you wish to have a clickable image, you must also define a link URL for the logourlĀ option if it is not already defined.
Logo height in the control bar fits other icons height, centered vertically. If the original image is higher, it will be scaled to the maximum possible height. Have a look at the Nuevo plugin code setup.
Code snippet
<script>var player = videojs('example_video_1');
player.nuevo ({
logocontrolbar: '//domain.com/path/to/logo.png',
logourl: '//domain.com'
});
</script>
