Quick start guide for installing JRiver Mediacenter 21 ARM for Raspberry Pi

OK Thanks - I thought I would need a script to launch in DISPLAY:1 rather than the bare command. I will try that.


I am using an IR remote with a USB receiver. CEC from the amp doesn't seem to work, although I'm sure it has done at some point. I may have un-ticked a box in the options.

CEC from the amp is my by far my preferred option, so it would be great to get that working, especially if I could use (for example) the 'up arrow', or any other button to remap and start/kill MC. That would really be awesome!

If I think back, CEC from the amp/DAC might only have worked when I had a monitor attached to DISPLAY:0, so maybe that is an issue

I have just installed MC21.0.28 on an RPi2 running Jessie following this very useful guide, and have run into two initial problems:

1) I cannot close MC21.  If I try to close the program using either the red X icon or File >> Exit (or any other method), MC21 hangs.  The RPi is not frozen (I can restart the Pi), but the MC21 window is unresponsive. The only way to close MC21 is to reboot the Pi.

2) I was able to restore from a MC21 library created on my Mac, but could not restore the settings (only the files themselves).  That means I have to recreate all of my customizations (e.g. what shows up in the title bar during playback, or which fields show by default in the tagging window).

This may or may not matter, but my music files are stored on a Synology NAS and shared with the Pi2 using CIFS mounted read-only. However, the file locations in tools-->Options are local to the Pi (and are all the defaults).

Thanks for any assistance,
Jim

I was able to solve the first issue (MC21 will not close) by adding "sudo" in front of "ps -e | grep mediacenter || mediacenter21 /mediaserver" in my ~/headless file from M Willems' guide to running headless on an RPi2.  Are there any major downsides to running MC21 as root?

Thanks,
Jim

Update: running MC21 with sudo only fixes the "no close" problem for a little while.  Maybe this has something to do with the VNC session going to sleep at some point after rebooting the Pi?

I recently executed sudo apt-get update, and noticed that the first line on the console says
"Hit http://dist.jriver.com wheezy InRelease"

Could this be my problem since I am running Raspian Jessie?  Do I need to reinstall MC21 for jessie by somehow changing something in the following?

wget -q "http://dist.jriver.com/mediacenter@jriver.com.gpg.key" -O- | sudo apt-key add -
sudo wget http://dist.jriver.com/latest/mediacenter/mediacenter21native.list -O /etc/apt/sources.list.d/mediacenter21.list

Again, many thanks in advance for tolerating all of my Linux noob questions.

I'm a relative Linux Noob, but am finding my way around.  Have access to an expert as well - lol

So, I have a Raspberry Pi 2B
It came with the preloaded Noobs card (Raspbian Wheezy)
I have followed the instructions above, but when I try launch MC in the GUI,  I just get a white panel / window that overlays the GUI.  JRMC21 shows up on the Panel at the top of the screen and I can close the white window by closing MC from the panel at the top of the Linux GUI .   I see the CPU spiking as if it were starting an app, but that's all.  

Any idea what I might have done wrong?
