Hi @nagai_kazuki,

Thank you for the detailed bug report on the Shaka Player crash/hang issue with your MPEG-DASH dynamic ClearKey stream.

Our team is investigating the problem where playback crashes or hangs at stream switch points, particularly the codec-related error you’ve identified: “Either mp4a is not a supported audio codec or its a video codec.”

This level of detail is extremely helpful for our investigation. We’ll provide an update as soon as we have more information about the root cause and potential resolution.

Thanks for helping us improve the Vega platform.

Warm regards,
Aishwarya
