Why are the extra codecs causing errors for the Media Source API?

When I attempt to enhance video playback capabilities by incorporating additional codecs, it unexpectedly leads to errors within the Media Source API, which is crucial for dynamic video streaming.
This complication hampers the seamless adaptation and quality switching features I aim to implement for an optimized viewing experience. What could be the underlying reasons for these codecs to disrupt the Media Source API’s functionality, and what steps can I take to diagnose and fix these errors without compromising on the video quality or streaming flexibility?
