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?

WX20240830-130335@2x WX20240830-110837@2x Throw an error catch in undefined

I guess it could be the line:

https://github.com/video-dev/hls.js/blob/01f50bbbccdf6dea92460b003c78d37a5ecf904e/src/controller/eme-controller.ts#L1256-L1259

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

Chrome media internals output

No response

robwalch commented 2 weeks ago

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 commented 2 weeks ago

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.
