Please ask your question
I am interested in trying to measure potential benefits of using MSE in Web Worker for Shaka. I have found similar question #5008 and was wondering if there have been any changes in plans for supporting this functionality.
Additionally, as an alternative, I was looking into achieving this without changing shaka code by overriding a component that is responsible for handling MSE. I believe that would be MediaSourceEngine, I am not sure if this is possible at all since it is not a plugin. Is there any option for me to create an extension class for MediaSourceEngine or some other way to change the core logic of the MediaSourceEngine without changing shaka code?
Thank you!

One of the major things preventing Shaka from running in a worker context was our use of DOMParser, which isn't available there. However, this was recently changed. In v4.8.0, Shaka should be able to run without DOMParser.

I don't know much, but I expect it would be best to have some division within Shaka to allow some subset of components to be optionally hosted in a worker, with messages exchanged between the main player and those worker components. I'm sure MediaSourceEngine would be part of that, but I'm not sure what else. StreamingEngine? A copy of NetworkingEngine? I also wonder if we'll have trouble with any configuration shared between these two halves.

If you're interested in pursuing this, please make a proposal! I'm open to changes to the structure of the project to enable use in workers.

Thank you for getting back to me so quickly with this! I am gonna look into v4.8.0 without the DOM parser next week, try to estimate locally what changes would be required for that and get back to you with a more detailed proposal.
