Interactive Video

How to force users to play HP5 interactive video on landscape mode

One  solution which I found is updating a property in Library.json

Are there any other solutions

Is there any place in source code where we can update the  property in library.JSON, so that it is applicable for all the new videos

Please forgive if this is a repeat.  I am new and I don't see my other post.  I don't know if I'm supposed to see my own posts in the forum.  

I have a multivideo page with about 60 H5P videos (1-5 minutes each).  It's a summary search page of all the bookmarks on my site (educational). Elsewhere, it's one H5P video per page.  This is a "site index" of all the bookmarks in one place. 

These videos all have bookmarks.

About 10 will play and bookmarks and videos work.

Can anyone tell me what the eye with the line through it means when I view the H5P content bank in this Moodle course? As you can see in the attachment, there are several H5P activities in the content bank for this course and two are marked with an eye with a line slashed through (which would imply to me that it's hidden or something like that). The activities can still be added to the Moodle page and students can still interact with them. They seem to be functioning normally. Has anyone seen this who can tell me what it means?
