So far, the mux.js team doesn’t know what is wrong with their CEA parser on this content, and neither do we.

If you have access to an open-source CEA parser in any language that works with this content, we could compare it with mux.js and see if we can identify the issue.

In the mean time, while we wait on either the mux.js team to provide a resolution or a working CEA parser to compare with, we will have to remove this issue from the v2.6 milestone.

We apologize for the inconvenience.
