Comment 1 for bug 1652997

The only way to fix this at the moment without dev work is to tweak the embed code manually in Mahara with a height that would work. e.g.

Instead of
<iframe src="https://media.xjtlu.edu.cn/player?autostart=n&fullscreen=y&width=0&height=0&videoId=5656&quality=lo&captions=n&chapterId=0" frameborder="0" scrolling="no" style="position:absolute;top:0;left:0;width:100%;height:100%;" allowfullscreen></iframe>

Recommended
<iframe width="500" height="400" src="http://media.xjtlu.edu.cn/player?autostart=n&fullscreen=y&width=0&height=0&videoId=5656&quality=lo&captions=n&chapterId=0" frameborder="0" scrolling="no" allowfullscreen></iframe>

Two ways going forward:

1. Your platform changes its code to generate height and width options that are more aligned to what other social media platforms do.

2. Mahara change to investigate: If the iframe width and height are not working, be able to override them by entering values into the width and height fields that we have rather than ignoring those fields.
