Docker continaer on Raspberry Pi has a bad ffmpeg binary

[apastuszak]

I used docker compose to build a koozic docker image and container and got it fire up and I could log in. But koozic will not play any music.

When I went into the console for the container and tried to run ffmpeg, I get the following error.

root@a59536472f3d:/# ffmpeg bash: /usr/local/bin/ffmpeg: cannot execute binary file: Exec format error

This seems to be indicative of an x86/x64 binary in an arm container.

Is it possible to completely disable any kind of transcoding and just have koozic play the file as-is?

Hello, In the playlist configuration, you can set the Audio Mode to 'No transcoding'. https://doc.koozic.net/music/playlists/playlists.html#fields

Ok, changed the Audio API to Web Audio API and turned on No Transcoding. Music still won't play.

[DocMarty84]

Activate only No Transcoding. Did you try to refresh the page ?

I did that and stopped and started the container. Is there some kind of logging I can enable?

[DocMarty84]

Stop the container: docker-compose stop Start without the daemon mode: docker-compose up You'll get the log on the standard output -------- Original Message --------

There is nothing useful in the standard output. Here is what I am seeing now:

If I add anything to the playlist I have set not to transcode, it seems to play fine. If I just browse my library and click on a track to play, the HTML5 player "loads" the file, but it never plays.

And nothing will play using any iOS subsonic client I tried. Is there any way to tell koozic to never transcode any files that are played, regardless of how they're played, system-wide?

[DocMarty84]

The behavior you describe does seem coherent. Transcoding is the default behavior unless specified differently for a given playlist. But that means it only applies to the playlist when played in the web browser. When you play a track directly, it is not added to the playlist, therefore it doesn't follow the playlist configuration. Same goes for the Subsonic app. 2 solutions I need to check: - include a ffmpeg binary for ARM in the Docker installation. But the RPi might be overloaded by transcoding since it doesn't have much CPU power. - add an option to never transcode, whatever the configuration. At the moment there might be a workaround, assuming your files are in the MP3 format. Indeed, Koozic does not transcode a file if: 1. The file has the same format than the output format 2. The requested bitrate is larger than the file bitrate. Therefore, you could: - go in Configuration > Transcoders - move the MP3 transcoder to the top of the list to give it the priority over the Opus transcoder That should solve the issue when you play a track directly, i.e not from a playlist. Regarding Subsonic, make sure your application requests the highest possible bitrate. By the way, I suggest the app Soudwaves for iOS: https://itunes.apple.com/app/soundwaves/id736139596?mt=8 Hope it helps. PS: I'll have a look at the mentioned solutions at the beginning of August since I won't have computer access in July. Sorry for the bad formatting, replying from email...

I would prefer if it never transcoded. I have a mix of MP3 and M4A files and I would prefer they be sent "as-is." But you're not writing this for me, you're writing it for you.

And don't apologize for anything. You wrote something and gave it away for free. In my book, you win always.

[DocMarty84]

Thanks for the support 😉

Indeed I wrote it for me, but it's better if it can be useful to others. I'll have a look to make the "No Transcoding" a possible default option. I just need to think of a clear way to make it available for end users, since I want to keep the interface as simple as possible.

I'll work on it at the beginning of August and keep you posted.

[apastuszak]

Thank you!

Hi! A "no transcoding" option would be great as I am facing this exact same issue on my ARM device. If you end up implementing this option, please do keep us posted :)
By the way, I still can't play tracks directly even after changing the "Configuration > Transcoders" option as you suggested, but I do when playing from a playlist after setting "No Transcoding" as the Audio Mode. Just FYI.

[DocMarty84]

@peguerosdc Are you also using Docker?

[peguerosdc]

@DocMarty64 yes

[apastuszak]

Considering the processing power of a Pi, I think it would be best to simply have an option to disable transcoding completely. Andy

Yes, that's what I'm planning to do.
