ffmpeg transcode AAC error

I'm getting an error in my MediaBrowser logs about a transcoding error, referencing AAC and the way it's attempting to work. This only happens with some movies and not others.

  Code:

2019-09-11 12:54:23,128 WARN  [ProcessExecutor] Process ffmpeg has a return code of 1! This is a possible error. Detailed output follows.
[aac @ 0x13e3380] The encoder 'aac' is experimental but experimental codecs are not enabled, add '-strict -2' if you want to use it.
[aac @ 0x13e3380] Alternatively use the non experimental encoder 'libfdk_aac'.

Any assistance would be appreciated.

Serviio 2.0 | CentOS v7

[zip]

this looks like an old version of ffmpeg. You will need to compile your own new version or get one from a repo. Currently using 3.2.4

Hey zip... I am still trying figure out this FFMPEG issue, but I noticed that the 2.0 download page says that FFMPEG is actually included in v2.0. I've removed the installed RPM I had for FFMPEG, but now Serviio says it can't find it at all. Please advise.

zip, correct me if I am wrong.

I believe the Windows and Mac versions include ffmpeg in v2.0. The Linux versions do not, because they can be obtained from your distribution (RPM, YUM, APT, etc.), or compiled from ffmpeg.org.

I don't like that you're right.. I love linux, and for stuff like this, it's always so frustrating. Attempting to compile FFMPEG now...

You're brave. I would just use yum. CentOS is good like that...

On the bright side, with CentOS, once you have it up and running, you probably can just leave it alone (occasionally update and reboot), and it will continue to work just fine 2 years from now...
