@Pehrsons Ideally the reading and writing could be performed without playback of the media, a precusor, related concept https://github.com/guest271314/OfflineMediaContext. `OffscreenCanvas` does not necessarily provide that functionality of [`OfflineAudioContext()` ](https://developer.mozilla.org/en-US/docs/Web/API/OfflineAudioContext)

> doesn't render the audio to the device hardware; instead, it generates it, as fast as it can

that is, throughout the process or recording video/images, a `<video>` elements essentially MUST be used and video MUST be played back to get the video data. There is no `.decodeVideoData()` to get the underlying images WITHOUT playing back the video.
