I am happy to confirm that I can help you with integrating the IMA SDK into your HTML5 video player using Plyr. I have the knowledge and experience necessary to perform this task.
To get started, I'll need access to your project files and your ad server account for the IMA SDK. Once I have those resources, I'll be able to effectively integrate and make sure the pre-roll ads display correctly in your video player.
Please provide me with more details about your project, such as the specific version of Plyr you are using and any other configurations or particular requirements you have. It would also be helpful if you share the relevant files and login information for your ad server account with me.
I look forward to hearing from you so I can start working on your project and integrate the IMA SDK into your HTML5 video player. If you have any other questions or concerns, please don't hesitate to let me know. I am here to help you!
