MediaInfo could not be loaded libmediainfo.so.0

[macf0x]

This error doesn't appear immediately, but after running (presumably processing) it appears in the logs. No noticeable issues, but possibly impacting download completion handling when there is a sample included.

Error has been present from installation. Given the delay it takes for the error to appear it makes it difficult to pinpoint.

MediaInfo and dependencies are installed and the library are present in the Mono directory.

The mono debug logs show failed attempts to load a library /share/MD0_DATA/.qpkg/QSonarr/NzbDrone/libmediainfo.so.0.so but only /share/MD0_DATA/.qpkg/Qmono/lib/libmediainfo.so.0

Is this a mono related configuration issue or Sonarr config issue?

symlinking the mono library to the NzbDrone seems to have removed the error, but I'll wait and see if this fixes the issue.

cd /share/MD0_DATA/.qpkg/QSonarr/NzbDrone ln -s /share/MD0_DATA/.qpkg/Qmono/lib/libmediainfo.so.0 libmediainfo.so.0.so

Is this a mono related configuration issue or Sonarr config issue?

It looks like the wrong filename for MediaInfo was included in the QSonarr package, making it a QSonarr package issue (which is made by a 3rd party).

Thanks Markus,

So far so good. Will need to raise the issue with the packager.

Post to packager - reporting issue

@markus101 Can you elaborate on why Sonarr looks for the library in this path? I have spoken to the pack developer and they're not clear why either. The library path is being set in the start/init script.

export LD_LIBRARY_PATH=/opt/Qmono/lib:$LD_LIBRARY_PATH
I'm not a Mono expert, but wish to help fix the issue. Does Sonarr specifically reference/load this library from a path or is it configured with a mono config file.

It's looking for a specific filename, not a specific path, the filename it looks for is libmediainfo.so.0 (the extra .so on the end of the file in the QSonarr package seems wrong).

The paths it look for are specific by the system (or any startup scripts), but if your symlink in #1488 (comment) worked then it's not a path issue, it's a file name issue (the trailing .so).
