Original GitHub issue: https://github.com/koel/koel/issues/396

Using the Chrome browser (up to date), I just updated my installation to the latest master branch a few hours ago. I can no longer play transcoded FLAC files with the following error appearing in my console:

undefined:1 Uncaught (in promise) DOMException: Failed to load because no supported source was found.

I can replicate it with any of my FLAC tracks. Was working earlier today, but after the update, this problem started. Can try and look into debugging it later, but thought I'd go ahead and file an issue.

I had the same error after a force sync yesterday, but I don't believe it had anything to do with FLAC files, I will double check.

I had the error when I ran an unsuccessful force sync with my audio files located in a new folder, but I solved everything by pointing the path to the old location.

@bdgold I double checked some of the files and the paths are correct in the database though. Running a force sync isn't really ideal. With 40k+ files, it takes HOURS to do a full sync.

Any information on how to fix this without running that would be awesome.

Also, unusual this issue is only on FLAC files. Everything else I've tried seems fine.

40k+

Are those music files or just files to scan?

Hmmmm, I had a music library with 48k songs and loading koel was a disaster, are you experiencing the same?

Loading koel is a disaster with my library. I wrote my own front end that is an iTunes clone (I posted a premature demo in a previous PR) and it runs as smoothly as a native app. I didn't build it to be mobile friendly though. If you're interested in trying it out let me know and I can shoot you a link. Uses koel backbend.

As far as this issue goes, this issue does occur in the official koel code and front-end.

I just changed $transcode = to null and it works again.

Once it works there is still a 500 error on getting info.

Update

Even with null not all are working, some still give the same error.

I acknowledge this. Some changes in the recent Chrome version(s?) seem to have broken transcoding-streaming. Will certainly look for a workaround when I have time.

@phanan I believe there are some breaking changes in github.com/phanan/koel@65d403f857
on github.com/phanan/koel@a87b456f9b everything plays as it used to for me.

@alex-phillips can you run git checkout a87b456f9b140447c3c25f6a16f396a4d658e323 and see if it works again.

On master I have the issue in Firefox as well

@bdgold That checkout does work for me. I can play FLAC now.

Site note: is the email on your Github page good to contact you with the frontend information? (@bdgold)

I have now the weirdest thing.

I was doing some tests with Koel and changed the STREAMING_METHOD to php, after that I'm unable to get Opera to play any files, I believe I have tried everything. Firefox and Chrome are working.

The error? undefined:1 Uncaught (in promise) DOMException: Failed to load because no supported source was found.

UPDATE

Opera just magically just began working again, I don't know why, but maybe it was cloudflare clearing some cache that I forgot to purge when I was done testing :-/

@phanan does Koel check the STREAMING_METHOD on every play request? or does it store it somewhere?

Right.

So if I were to set it to some gibberish STREAMING_METHOD=gibberish what should the expected behavior be?

Does default: return PHPStreamer for anything that is not 'x-sendfile': or 'x-accel-redirect':? or unless its set to one of the 3 it should fail?
