[How-To] Set up JRiver Media Center 26 in Debian/Ubuntu/Linux Mint

<< < (6/7) > >>

Hendrik:
Bob and I talked about the version requirment a few weeks ago, and its likely that we'll keep the current setup for MC26 for now, and change over to a Buster base for all variants in a future version, likely late this year.

Hi all,

I've been running Mediacenter for a few years now and have just upgraded to Ubuntu 20.04 LTS (Focal Fossa)

When running mediacenter26, it opens and seems to work fine until a movie is played.  Music works fine.
Once played it immediately crashes.
I could not find log files anywhere for this, so I ran from the commandline and got the following output:

bchaps@cangrejo:~$ mediacenter26&
[1] 81166
bchaps@cangrejo:~$ double free or corruption (out)

[1]+  Abortado                (`core' generado) mediacenter26

Any ideas?

Thanks!
bill

I've also been seeing segfaults for video on one machine lately, but I assumed it was related to my graphics card (an AMD 5700XT, which still has relatively "experimental" Linux support, I see no issues on other machines with integrated graphics). 

What kind of graphics hardware are you using?  Did MC26 previously work on this machine with the older version of Ubuntu?

--UPDATE - I can play movies from Theater View - but not from a playlist.  That is strange!  But, it only made it half way through the video.
--UPDATE2 - Flattened and rebuilt.  Basically the same issue.  Discovered that if I play photos from the image gallery first, then i can start a video.  Audio works perfectly fine.  Definitely a video issue.

Hi mwillems,
  Yes, I was originally running MC 24 (on Mint), then later 25 & 26 on the previous version of Ubuntu on this laptop. 
It is an Asus Zenbook with the regular Intel integrated graphics.
Since upgrading, I've rebooted (many times), uninstalled, reinstalled, restored from the previous days backup and even dug through the video configuration and did not find anything interesting.

This feels like one of those issues that happens because of an upgrade and is near impossible to track down. Maybe this weekend, I will flatten and rebuild from scratch since it will be raining out. :)

I am using an RME ADI2 pro on Ubuntu. Everything is working fine, except that I can only upscale PCM to DSD64 and not higher.
If I try to set it highter then the music is playing not smoothly.
