HLS / DASH Compatibility Checker
A structured public layer for M3U8, subtitle, and video helper workflows.
The legal-page color system becomes a formal theme preset.
Execution still stays behind the public layer.

HLS / DASH Compatibility Checker
Check browser capability, manifest reachability, and lightweight HLS or DASH structure before you escalate into heavier playback debugging.
Manifest QA, browser capability, fetch visibility

Best use cases
HLS / DASH Compatibility Checker
Use this checker when you need a fast QA answer about manifest structure, browser support signals, and source visibility before moving into a player or deeper parser.
Check whether the current browser reports native HLS, MediaSource, or obvious playback limits before you blame the player.

Recommended route map
Qualify compatibility first, then branch into playback, access checks, or parsing.
The compatibility checker should narrow the issue before you jump into the wrong execution lane.
Open HLS Player
Use this when HLS structure and browser support signals look sane enough to try playback.
Open routeOpen DASH Player
Use this when the MPD looks sane and you want an actual browser playback checkpoint.
Open routeOpen M3U8 Link Checker
Use this when fetch visibility or URL access is the real blocker instead of manifest structure.
Open routeKeep compatibility checks tied to the next useful page.
- HLS Player Try browser playback after the HLS manifest and browser capability look sane.
- DASH Player Try browser playback after the MPD and MediaSource support look sane.
- M3U8 Inspector Move into deeper manifest inspection when the issue is inside the HLS structure itself.
- HLS Playback Error Use the playback guide when compatibility looks plausible but playback still stalls, buffers, or errors.
Compatibility checker FAQ
- Does this page guarantee that HLS or DASH playback will work everywhere?No. It compares browser support signals, fetch visibility, and basic manifest structure. Real playback can still fail because of codecs, DRM, CORS, auth, or player runtime differences.
- Why allow pasted manifest text or local manifest files?Because many manifest URLs are blocked by CORS or auth. Pasted text still lets you inspect structure without pretending the remote URL is reachable from the browser.
- When should I open HLS Player or DASH Player instead?After compatibility looks sane. Use the player pages when you need actual playback behavior, not just a browser-side compatibility qualifier.
