Ashley- the iframe plug in has no way of recognising when an embedded video has finished playing i.e on video finished > action. Using the video plug in works perfectly for what I need however I have many videos that I would need to import into the project hence Webm due to filesize and having a popup tell users to use Chrome browser instead (to ensure compatability).
This is why I also wondered if there is a way to download videos to the webapp during use and not just when you initially load the page.
Elliot- I'm fairly new to all this so this helps.
Ultimately, my whole problem is solved by the iframe being able to recognise when an embedded video finishes playing.
