What an MPD contains

A Media Presentation Description lists periods, adaptation sets, representations, segment timing, and media locations. The manifest is an index, not the playable media itself.

Before you test

Confirm that the manifest and segments return the expected MIME types, are reachable from the browser, and use codecs supported by the device. CORS can block either manifest or segment requests.

Choose the right follow-up

For HLS use the Manifest Inspector. For format selection, compare HLS, DASH, and MP4. For blocked requests, start with the CORS Checker.
