Docker Image for MC28
crypticc:
Hello
I'm trying out JRiver running in docker container on my QNAP
I have managed to get it working including both as DLNA server and DLNA controller. But I can't get it to act as a local player. Or rather I can but I don't get any audio
this is my first post but I'm hoping to have done enough b4 asking for help here that someone more experienced might be able to help.
Thank you
Chris
This is my docker-compose.yml file

I added all the USB looking devices into cgroup devices although i think it's 189 which is the actual device
If relevant this is the USB device I'm trying to output to

The USB device is irrelevant you can select what output you want in alsamixer on your docker host.
Test if you can play audio with aplay on the system first (not in the container).
You need a working alsa on the docker host for it to work in the container.

Is it possible to get Hardware-Accelerated Encoding to work with Docker? I have a Synology DS220+ with an Intel processor that is capable of this, but the CPU is pegged when it is converting MP4 videos (h264,aac) with the option checked in MC.
max096:
Currently not an option built into the container. You can try to install it yourself. You'd need Intels drivers in the container, expose the GPU device to the container and give the user that you configured to run the container as permissions to use it by adding it to the render group (inside the container).
This seems how they do it for jellyfin mostly it should be the same https://forum.openmediavault.org/index.php?thread/38696-how-to-activate-intel-quick-sync-in-docker-jellyfin-handbrake/
To set the group you can mount an additional init script like this one https://gitlab.com/shiomax/jrivermc-docker/-/blob/master/rootfs/etc/cont-init.d/10-check-snd.sh
You can mount another script to /etc/cont-init.d/10-set-render-group.sh or similar.
--- Code: ---#!/usr/bin/with-contenv sh
echo -n render >> /var/run/s6/container_environment/SUP_GROUP_IDS
--- End code ---
Hope that helps. If you get it working you could share the init script / steps. Could add it as an option to setup in the container then.
The script that adds the audio group if you passed threw /dev/snd would interfear with it if you did that as it overrides that variable at startup too. This worked for now because there was only one group to add but there would have to be additional checks to not blindly override SUP_GROUP_IDS but append to it if something is already there. It's supposed to be a comma separated list. So better to not pass threw /dev/snd for testing now.

Thanks. I might try it but I am not very skilled in Linux.
