HEVC or AV1 Codec Support

[Ady88w1]

Hi,

I notice that HLS JS does not currently support HEVC or AV1 codecs for browsers that do support them (Safari for HEVC, and Chrome for AV1). When using these codecs in a compatible browser, the stream will play without video (audio only).

Are there plans to support these codecs in future?

Many Thanks,
Ady

Hi @Ady88w1

We already have an open request for HEVC support here #2451

I'm interested in hls.js supporting more codecs, but that depends on browsers supporting the codecs via MSE. Safari supports HEVC with video.src = url. Does it via MSE? Chrome on the same device might not.

I assumed most AV1 delivery is done over DASH - the idea being that HLS streams are always Apple device friendly.

We'd also need test vectors or sample streams to work against. Contributions are welcome.
