XWikiTube potrait mode

Dear all,

I’m wondering about the following:
I’m using XWikiTube (Which is great!) to include video material in my XWiki. However I want to include videos from mobile devices which are captured in potrait mode. When I include them (after conversion into mp4) with XWikiTube I get always a video in landscape with the video in potrait and a black area on the left and right so that the landscape area ist filled. DUring th encoding I see all modes are in landscape orientation. Any idea how to change this , so that the videoa are embedded in potrai mode?

Any help is welcome
