VLC cannot play MKV files?

[Vincent Habchi]

Hi René,

> Any MKV file? What VLC version?

Latest one:

port installed | grep VLC
VLC @2.1.5_7+mod+mpc+osd+qtkit+quartz (active)

> What does the VLC log tell you (either in-app or by launching the app bundle executable directly from a terminal, with the -vvv argument)?

You will find the relevant part of the log hereafter. It seems VLC does not recognise the header, and there is an unknown error at some point that looks ominous.

Thanks for looking into this!
Cheers!
Vincent
