Video Commander

HLS & DASH Validator for macOS

Malformed manifests, missing segments, and inconsistent bitrate ladders are some of the hardest streaming bugs to catch before they reach users.

Video Commander includes a built-in HLS and DASH validator for macOS — so you can catch packaging issues at your desk, before they become playback failures in production.

Frequently Asked Questions

What is an HLS validator?
An HLS validator checks that your HLS stream is correctly formed — including manifest syntax, segment availability, codec consistency across bitrate variants, and timing correctness. Problems here cause playback failures that are hard to debug without tooling.
Does Video Commander validate DASH as well as HLS?
Yes. Video Commander supports validation for both HLS (.m3u8) and DASH (.mpd) streams.
Can I validate local streams or only remote URLs?
Both. You can validate streams hosted remotely or inspect packaged output on your local machine before publishing.
Does it work on Apple Silicon Macs?
Yes. Video Commander runs natively on Apple Silicon and also supports Intel Macs.
