I’m trying to add the mobile version of my video component extension.  
Everything works but the sizes are obviusly different.  
Is there a default size for the mobile view or it depends on the phone?  
Is it possibile to autoscale like in the video componet view?

use responsive design.

iirc I’m using 318px width as dimensionally mobile is similar sized to a panel. But I use responsive design elements so it resizes dynamically
