Interactive Video

Issue:

Interactive video is loading slow for the first time.

Noticed that the HP package is having libraries which I don't use, is it possible to  avoid those in the package with configuration or source code change.

If this libraries were avoided, the h5p file size would decrease. would it improve the performance.

If so where do we need to do the change in the source code.

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.
