MKV metadata cropping doesn't work
Posted: 08 Nov 2014 22:51
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:
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?

VLC media player 2.2.0-rc1 Weatherwax (revision 2.2.0+ppa2.4)
