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.br />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>
