MetadataExtractionCoordinator Fails on Every File

Serviio Pro 2.0 refuses to scan any of my media files into the library.

Audio files give this error:
  Code:
[MetadataExtractionCoordinator] Skipping processing metadata for an unsupported file (/PATH/TO/ANY/MUSIC/FILE.M4A). Message: MP4 file '/PATH/TO/ANY/MUSIC/FILE.M4A' has unsupported codec (Alac)

Which is weird because it says "Apple Lossless ALAC (.mp4)" right on the Features page.

Video files (regardless of extension or format) give this error:

If I run the ffmpeg command manually, it does not throw any errors:

I am running Ubuntu 18.04.2 LTS:

  Code:
4.15.0-54-generic #58-Ubuntu SMP


  Code:
openjdk 11.0.3 2019-04-16
OpenJDK Runtime Environment (build 11.0.3+7-Ubuntu-1ubuntu218.04.1)
OpenJDK 64-Bit Server VM (build 11.0.3+7-Ubuntu-1ubuntu218.04.1, mixed mode, sharing)


I compiled FFMPEG from the source given in the readme.
http://download.serviio.org/opensource/ffmpeg-3.4.4.tar.bz2
Using the following options:
  Code:
PKG_CONFIG_PATH=/opt/serviio/ffmpeg/lib/pkgconfig ./configure --enable-gpl --enable-libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libtheora --enable-libvorbis --enable-libx264 --enable-nonfree --enable-postproc --enable-version3 --enable-librtmp --enable-libxvid --enable-libass --enable-libxcb --extra-cflags="-I/opt/serviio/ffmpeg/build/include" --extra-cflags="-I/opt/serviio/ffmpeg/build/lib" --prefix=/opt/serviio/ffmpeg/


With Lame and x264 compiled from the links in the readme.
http://download.serviio.org/opensource/last_x264.tar.bz2
http://download.serviio.org/opensource/lame-3.99.5.tar.gz

Serviio runs with this command:
  Code:
java --add-modules jdk.unsupported -Xmx512M -Xms20M -XX:+UseG1GC -XX:GCTimeRatio=1 -XX:MinHeapFreeRatio=10 -XX:MaxHeapFreeRatio=20 -Djava.net.preferIPv4Stack=true -Djava.awt.headless=true -Dorg.restlet.engine.loggerFacadeClass=org.restlet.ext.slf4j.Slf4jLoggerFacade -Dderby.system.home=/opt/serviio/library -Dserviio.home=/opt/serviio -Dffmpeg.location=/opt/serviio/ffmpeg/bin/ffmpeg -Ddcraw.location=dcraw -classpath /opt/serviio/lib/*:/opt/serviio/config org.serviio.MediaServer


Apparently the central issue (at least with the ffmpeg pipe) is that the files are on a mergerfs fuse mount.
Testing Serviio on files stored directly on a local drive fixes the "No such device" error and allows importing of video files.
But the way I store my media files, Serviio needs to be able to read them off of the merged fs.
I read that disabling direct_io might fix the underlying java problem, but that is not an option due to the way one of the underlying file systems handles caching.

Is there any fix for this problem?

Re: MetadataExtractionCoordinator Fails on Every File

Hi,

the Alac issue is a bug, will be fixed for the next version.

Re: the pipe issue, I'm not entirely sure what the fix is. Does this mean pipe: is not a valid ffmpeg device?

Happy to know the ALAC issue is a fixable bug.

I am not a Java developer, but from what I was able to glean from the Internet, java.nio is complaining about the underlying filesystem being a FUSE mount with the direct_io option enabled. It is not at all clear to me why Java cares about the underlying filesystem since it seems to be reading from a pipe created by FFMPEG. But, if I point Serviio to a real filesystem it indeed has no problem picking up the (non-ALAC) files.
