We shouldn't require track transferability #113
Description
The current version of the API requires track transferability, but this shouldn't be necessary.
Currently, tracks are useless on workers except for this API, so we shouldn't add that as a requirement.
A way to keep the API worker first which has several benefits is to follow the postMessage-like approach of webrtc-encoded-transform.
Something (subject to discussion) like:
For MediaStreamTrackProcessor:
// main
navigator.mediaDevices.createTrackProcessor(myWorker, mytrack, myOptions, [myOptions]);`
// worker
ontrackprocessor = event => {
let processor = event.processor;
// Process frames using processor. `event.options` has the data sent via myOptions for extra configuration.
}
For VideoTrackGenerator:
// main
let generatedTrack = navigator.mediaDevices.createVideoTrackGenerator(myWorker, myOptions, [myOptions]);`
// worker
ontvideorackgenerator = event => {
let generator = event.generator;
// generate frames for `generatedTrack`. `event.options` has the data sent via myOptions for extra configuration.
}
