@theodab can you review it? Thanks!

Would it be possible to make a test for this?
Like, maybe something based on the 'parses media playlists directly' test inside the HLS unit tests?
You could just add a TS test asset, like '/base/test/test/assets/video.ts', to the list of media files the tests load, associate that with a URI when setting up the fakeNetEngine, and see if the resulting manifest has a width and height.
