Contact M3U8toMP4.org for HLS Browser Tool Support

Contact M3U8toMP4.org about public test streams, browser errors, accessibility, privacy, security, or corrections to M3U8 technical guides.

How to report an M3U8 to MP4 conversion problem

Describe the exact step that failed: manifest analysis, a child playlist request, a media segment request, FFmpeg loading, remuxing, re-encoding, or final download.

Include the browser and operating system, visible HTTP status or error detail, and a public reproducible sample when possible. A screenshot with private tokens removed can be useful.

What not to send with an HLS support request

Do not send copyrighted media, signed private URLs, session cookies, Authorization headers, encryption keys, account credentials, or personally identifying log exports.

The project cannot retrieve restricted streams or provide guidance for bypassing DRM, authentication, paywalls, or a media owner's access controls.

How to suggest an M3U8 technical guide correction

Cite the page, the specific sentence, and a primary technical source such as an RFC, browser vendor document, or library documentation. Corrections that make limitations clearer are especially valuable.

Security disclosures should include a minimal reproduction and impact description without accessing other users' data or disrupting the service.
