The shortest way to reproduce this issue is to run this in the console of the Shaka Pleyr demo:

video.ui.configure({'castReceiverAppId': chrome.cast.media.DEFAULT_MEDIA_RECEIVER_APP_ID})

Then load and cast a video. You will see that the Shaka Player sender API is not compatible with the standard receiver.

However, the Shaka Player sender API was always intended to cast to a custom receiver app using the Shaka Player receiver API. It has never worked with the default receiver.

The Shaka cast APIs are deprecated and will be removed in favor of direct Cast support in the Shaka Player UI. This support will be compatible with the default receiver for content that the default receiver can play. (Currently this excludes DRM content, but I am now responsible for the default receiver, too, so this limitation could be lifted.)

For now, I'm going to call this WAI from Shaka's point of view. You can use the cast APIs in Shaka v4 on both sides, or you can use the Cast Sender SDK directly and use a non-Shaka receiver.
