I hope superuser.com is the right spot for this kind of issues.

Status quo:

Today i updated my BananaPi M1 to Debian Stretch (Armbian) and installed all packages I need from the plain Strech repo, no dev stuff or the like. The setup also includes mediainfo which I need for certain media center scripts.

My problem:

Running mediainfo on audio files, subtitles or whatever comes to my mind works as expected. Video files like .mp4 or .avi work as well but when I throw a .mkv file at mediainfo it just quits with an exit code of 1 and that's it. No error message, no nothing.

I had mediainfo running for years before without any problems or hiccups, but I wasn't feeling safe on an outdated Raspbian Wheezy, hence the upgrade. Can anyone tell me what's going on there with mediainfo? Are there certain interdependencies which I don't know of? Something very special with .mkv files?

I cannot recall performing any magic stuff in order to make mediainfo work when I set it up back then on Wheezy.

Any help is highly appreciated!

EDIT:

For testing purposes I installed the current version of mediainfo on my Windows PC and checked a few files. Here I'll post the Writing application and Writing library fields from mediainfo's output and note, whether I get the same output on my Linux machine:

File 1 (working):

Writing application     : mkvmerge v6.1.0 ('Old Devil') built on Mar  2 2013 14:32:37
Writing library         : libebml v1.3.0 + libmatroska v1.4.0

File 2 (not working):

Writing application     : mkvmerge v4.8.0 ('I Got The...') built on May 23 2011 22:50:52
Writing library         : libebml v1.2.0 + libmatroska v1.1.0

File 3 (not working):

Writing application     : mkvmerge v17.0.0 ('Be Ur Friend') 64-bit
Writing library         : libebml v1.3.5 + libmatroska v1.4.8

File 4 (not working):

Writing application     : mkvmerge v9.2.0 ('Photograph') 64bit
Writing library         : libebml v1.3.3 + libmatroska v1.4.4

File 5 (working):

Writing application     : mkvmerge v8.3.0 ('Over the Horizon') 64bit
Writing library         : libebml v1.3.1 + libmatroska v1.4.2

I can't deduct any consistent behaviour from these outputs. Any ideas on this? Does this help at all?

I solved it now by installing other versions of two libraries which mediainfo depends on, namely libmediainfo and libzen. Since I'm on Debian 9 (Stretch) I had to add the Jessie repo to my apt/sources.list as well in order to install older versions.

In doing this I replaced the libraries as follows:

libmediainfo0v5    ->    libmediainfo0
libzen0v5          ->    libzen0

I now have mediainfo 0.7.70 with the above mentioned libraries installed and it works.
