MKV metadata cropping doesn't work

The MKV format allows you to specify cropping settings in the metadata, so you can watch letterboxed videos without black bars without having to re-encode everything. Not many players support this feature. VLC used to support it, but it doesn't seem to work anymore. I use VLC version 2.2.0-rc1 on Ubuntu Linux. The debug output shows this:

Code: Select all

It does detect the cropping information, but it doesn't seem to do anything with it. I haven't been able to find anything about this issue, except an old bug report from three years ago (that bug was fixed). Is there a way to fix this or is there a reason this feature stopped working?

Hope MKV metadata cropping is properly supported
