Checklist

• The issue observed is not already reported by searching on Github under https://github.com/video-dev/hls.js/issues
• The issue occurs in the stable client (latest release) on https://hlsjs.video-dev.org/demo and not just on my page
• The issue occurs in the latest client (main branch) on https://hlsjs-dev.video-dev.org/demo and not just on my page
• The stream has correct Access-Control-Allow-Origin headers (CORS)
• There are no network errors such as 404s in the browser console when trying to play the stream

Steps to reproduce

1. Load the demo page https://hlsjs.video-dev.org/demo/?src=https%3A%2F%2Fstorage.googleapis.com%2Fshaka-demo-assets%2Fangel-one-widevine-hls%2Fhls.m3u8&demoConfig=eyJlbmFibGVTdHJlYW1pbmciOnRydWUsImF1dG9SZWNvdmVyRXJyb3IiOnRydWUsInN0b3BPblN0YWxsIjpmYWxzZSwiZHVtcGZNUDQiOmZhbHNlLCJsZXZlbENhcHBpbmciOi0xLCJsaW1pdE1ldHJpY3MiOi0xfQ== in the special chrome version
2. After a few seconds, click the detach media button
3. Check the console log

Expected behaviour

No Error thrown

What actually happened?

Throw an error catch in undefined

I guess it could be the line:

hls.js/src/controller/eme-controller.ts

Lines 1256 to 1259 in 01f50bb

	.concat(
	media?.setMediaKeys(null).catch((error) => {
	this.log(`Could not clear media keys: ${error}`);
	}),

media?.setMediaKeys(null) return undefined here. We may remove the catch.

Chrome media internals output

No response

[robwalch]

The compatibility section of the README states that HLS.js is supported on Chrome 39 and up.

https://github.com/video-dev/hls.js?tab=readme-ov-file#compatibility

Would you like to submit a PR to avoid this escape, assuming that optional chaining resolves the exception described above media?.setMediaKeys(null)?.catch((error) => {?

Was media detached intentionally or is the exception described a result of tear-down after a larger compatibility related issue?

[JackPu]

Sorry about ignoring the compatibility document about the hls.js usage.

And I would like to submit a PR to avoid the special case from your suggestion.
