it seems this box complains about FFmpeg DLLs not being available, seems an odd message on linux :)

any ideas?

MC needs to be able to download ffmpeg plugins to play some kinds of m4a.
Since your machine has an internet connection (or how would you play the stream?) it should just automagically download the plugin.

non-debian distro?
ssl client certificate store incompatible??

mattkhan:
It is exactly the same as the other box I provided logs for, i.e. my stock Linux setup which is Debian testing (with KDE as you require a desktop). The only difference is this is in a VM but it is not obvious why this would be an issue (famous last words).

What can I check to debug further?

Which plugin is it? I could install that manually to workaround for now?

You can't manually install it but you could try deleting the plugin directory and see if it loads the next time you try to play the stream (or perhaps play a local m4a file first?)

~/.jriver/Media Center 21/plugins/linux_avcodec/

You could also try ldd on the files in there to see if your OS is missing something...

mattkhan:
in fact there isn't even a plugins directory at all

I rsync'ed the dir over from my other box and ldd'ed each of the so's in there, everything is linked and now the stream works fine. I can't see any issues with the perms in that dir so I have no idea what the problem was.

It won't create the directory until the plugin is downloaded.
It's possible you needed to play a local m4a first. A bug perhaps...
