How to protect audio, video, image?

Question

Programming

Hello.
Please advise how you can protect user content on the site.
Everything is clear with the image - a watermark, easy to implement, there are ready-made js. If there are other interesting options, I'll be happy to listen.
But what about video and audio? I like the implementation of audiojungle and videohive , they put "Audio jungle" on the audio after a certain time, and watermark the video.
So the question is - how to implement such functionality for audio and video? Maybe there are some ready-made scripts?

An attacker can disable JavaScript. All conversions should be done using server programs (for example, written in PHP). It is better to manually overlay sounds on audio so as not to degrade the semantic quality of the audio clip. Videos can be watermarked using, for example, the ffmpeg package. Examples can be found by asking the question "video watermark php".
