JRiver Media Center 22.0.111-5 for Debian ARM

<< < (9/11) > >>

One more update. I now have 22 parametric EQ filters (frequency EQ from REW) as before combined with a stereo 16k-tap .wav convolution file (phase linearization from rePhase) running on the RPi 3, MC 22.0.75, and it's doing fine.  It gets a little uncomfortably high CPU playing 24/96 files, running around 2.5 - 3x real time and using about 65-70% of one CPU core on average.  16/44 files are running at 6.5 - 7x real time and use about 30-35% of one CPU core. I think I hear an occasional click when I'm doing something with the MC GUI which temporarily loads the CPU core higher, but while just playing music it seems to be running without issue. The default Raspbian "ondemand" speed governor seems to work fine; it bumps CPU frequency from 600 to 1200 MHz at 50% core usage.  Whenever MC is playing the core clock is 1200 MHz (settings are in the file /etc/init.d/raspi-config and from some searching it appears previous Raspbian releases may have set the threshold at 95%).

I appreciate the detailed testing information. It lets us know when we are bumping against the limitations of the system.

I have gotten Media Center to work on my Raspberry Pi 3 . However, the network & disk I/O on the Pi is too slow for my needs.
I'm considering purchasing an Odroid XU4 . This is an ARM single board computer . However, it uses Ubuntu as the default distribution, rather than Debian, unlike the Pi.

Is there any chance that Media Center would run on the Odroid ? I understand it won't have a Debian package installer, but could the bits be extracted manually ? Or is there no chance that it will run ?

Ubuntu is just debian with some bells and whistles (in my abbreviated definition).
There are lots of people running MC on Ubuntu and the architecture shouldn't make any difference. You would just run the Pi build and you should be able to install it with apt.

mwillems:
One thing to be aware of is that many previous odroid models lacked adequate color depth in their graphics driver to correctly display MC (i.e. only 16 or 24 bit color, I can't recall at this remove).  I never got MC working correctly on an ODROID C1 or U3.  The XU4 may have solved the issue, or may not have. If you install MC and start it, and only see an all white or all black window that's the color depth issue at work.
