I'm trying to use Web Codecs API to Decode HEVC stream(safari 16.4). However, when I configured the the Decoder like follow, it raise an rejection 'Config is not valid':

VideoDecoder.isConfigSupported({
            codec: &#039;hvc1.1.6.L120.B0&#039;,
            codedWidth: 1920,
            codedHeight: 1080,
        }).then(res=>{ console.log(res) }).catch(err=>{ console.log(err) })

I wander whether Web Codecs is supported HEVC decode in safari version 16.4 or I select a wrong codec string?

Curious if you ever solved this. I'm running into the same -- perhaps Safari does not yet support HEVC with WebCodecs?
