You can use JavaScript to inject custom buttons into the JW Player control bar. This code snippet adds a manual 10-second rewind button: javascript
JW Player requires its core JavaScript library to function. You can link to a cloud-hosted license key template or a self-hosted library file. In your CodePen settings, navigate to the tab and add the URL to your JW Player library under "External Scripts." Cloud-Hosted Example URL: https://jwplayer.com 2.

Combining JW Player with CodePen provides a fast environment for learning and prototyping. From basic video embedding to advanced custom controls, CodePen allows you to experiment with JW Player's robust JavaScript API in a live, shareable environment.
Because CodePen executes code from its own subdomains ( cdpn.io ), your video hosting server might block the request if it lacks proper Cross-Origin Resource Sharing (CORS) headers.

CodePen makes it easy to test video rendering, custom skins, and control states across various browsers and mobile devices. Setting Up Your JW Player CodePen Sandbox
This setup uses the CSS to constrain the container and the width: "100%" and aspectratio: "16:9" to instruct the player to fill its container while preserving its intended proportions. You can find numerous examples of this pattern on CodePen, such as the "fluid jwPlayer" or "Responsive Video Player" Pens. You can link to a cloud-hosted license key
Set the width as a percentage, enable responsive: true , and define an aspectratio for proper scaling.
In the JavaScript editor, you will write the code to initialize JW Player. Your script must come after the container div and the JW Player library to ensure all dependencies are loaded.
const playerInstance = jwplayer("my-player-container").setup( // Replace this with your own video URL file: "https://cdn.jwplayer.com/manifests/VIDEO_ID.m3u8",
