Koel Unable to Stream Larger Files

[robi]

@crazybrad is Koel up to date?

[crazybrad]

@robi It's a brand new installation. Cloudron version is 7.15.1 which matches GitHub master release level.

[robi]

Does the demo server have the same issue?

[crazybrad]

No. The demo server (https://demo.koel.dev/#/queue) plays just fine for me. I also have the same issue on Windows, so it does not appear to be Linux related. But interestingly, neither the demo site or my Cloudron instance seems to work on iOS Safari.

I think I have found something.
Regarding the max upload limit.
Yes there is /app/data/php.ini where you can add e.g.

upload_max_filesize = 5G
post_max_size = 5G

But, in /app/code/public/.htaccess is the following statement:

php_value upload_max_filesize 50M
php_value post_max_size 50M

This is nullifying the change made to /app/data/php.ini.

This is the first part. For this to be fixed, we need to release a new app update for Koel.

[crazybrad]

@james Impressive bit of detective work. Is /app/data/php.ini the proper way to set PHP settings inside Cloudron PHP apps? I understand that /app/code/public/.htaccess overrides this and that is a read-only area.

[james]

Now with a 1.42 GB big .flac file (which still fails to upload with UNKNOWN Error), directly uploaded via the Cloudron Web File manager.
The start of the song loads for 60 seconds and then returns a 500 Internal Server Error.
Maybe there is some internal issue with Koel and very big .flac files.
Smaller .flac files uploaded just fine and played just fine on Windows 11 FireFox, Chrome, Brave (chromium) and also worked on Linux the same browsers.

In some apps, yes.
Koel is one of these apps that allow custom php.ini configuration.
As a rule of thumb, if there is a php.ini in /app/data/ you can put config in there.
But, as you can see with this app, sometimes even upstream can place static limitations which are not documented https://github.com/koel/koel/blob/f5588bb519a066bf29afd1085b50f924f90125ec/.htaccess.example#L110-L111

Yes, there is a doc section here on the php.ini part:
https://github.com/koel/koel/blob/f5588bb519a066bf29afd1085b50f924f90125ec/docs/usage/music-discovery.md?plain=1#L98-L101

Depending on how big your files are, you may want to set upload_max_filesize and post_max_size in your php.ini

correspondingly, or uploading may fail with a Payload too large error.

This applies even if you’re using a cloud storage, as the files will be uploaded to your server first before being sent

to the cloud.

But the static .htaccess limitation is undocumented.

@crazybrad
Can you share how big the .flac file is you are trying to stream?

[crazybrad]

@james Sure. What's strange is I had no problem uploading .FLAC files at all. Just playing them. Files varied from 12MB up to 30MB.

[robi]

@crazybrad I actually meant Cloudron's demo server to rule out weird network issues, since you see it on windows too.

[james]

Hello @crazybrad
We just updated the Koel app and added a doc section to increase the upload limit.
https://docs.cloudron.io/packages/koel/#increasing-the-upload-limit

[crazybrad]

@james Perfect. Koel is working! Thank you. One suggestion, one question. Suggestion: you might want to add the period in the new documentation before htaccess (/app/data/public/.htaccess). Most users will understand the intent, but for inexperienced users, they might take this literally. Question: Based on the size of my FLAC files, I chose 100M as the "size" parameter. Do you have any thoughts on whether we should increase the application RAM to accommodate larger files on both upload and streaming and if yes, how that should scale with "size"?

Thanks for the feedback.
The dot generally has no meaning in file manager context or modern stuff for that matter.
Since the dot was/is used to hide files from file managers we decided to not use it in /app/data/ so users will see the file always.

Unfortunately I can't provide a good answer to this question.
If you see the app struggle with larger files, maybe what you describe is a good option.
Would be happy to get feedback on this topic from you after you gathered some experience from using the app.

@james My mistake on the .htaccess vs. htaccess. I am so used to using it with the dot and hiding it. I'm happy to experiment with different RAM settings and watch what happens with Koel.

[crazybrad]

@james Seem to be running into an interesting problem during uploading. So far with 100M as my "size" limits, I am unable to upload FLAC files larger than 50MB. I found out that htaccess, not the .htaccess file I created contained the operative limits: 50M. So by editing the correct file (htaccess) and fixing the limits, both larger FLAC files uploaded. My mistake!
