HEVC Codec Issue When Attempting to Play MSE in Chrome and Edge

[Vesperino]

When attempting to play Media Source Extensions (MSE) content in the latest versions of Chrome and Edge, I encounter an error indicating codec support issues. The specific error message received is:

"The type provided ('video/mp4; codecs="hev1.1.6.L120.90"') is unsupported."

This issue occurs across all tested browsers, which are updated to their latest versions.

Hmm, I still think it's not a hardware problem because this works fine on every machine: https://github.com/AlexxIT/go2rtc

@Vesperino
Because HEVC is not an open codec, most browsers do not include a built-in HEVC decoder. Instead, they rely on your hardware decoder for HEVC.

You mentioned go2rtc, and while it appears independent of hardware, it actually depends on it for HEVC decoding. As stated in the go2rtc documentation: Codecs Madness, "But HEVC/H.265 has a lot of limitations in supporting with different devices and browsers."
