How can i store a 50MB video in HTML5's app ca

Question

I'm developing an iOS offline app, and i'm trying to store a 50MB video for offline viewing. However after properly adding the video's url in my manifest.appcache, I got a console Error saying that the appcache limit exceeded the allowed size. Therefore, breaks my whole page; not one resource is loaded after.

As soon as I unlink the video from the appcache, everything works fine.

Is there a way i can circumvent this behavior ? Or, is there a way i can store a 50MB video on an IOS5+ iPad for offline view ?

Answer 1

There is probably no way to store your 50MB video. The current limit on iOS seems to be 5mb.

According to this answer to a similar question it's possible to raise it with some trickery, but that's probably not an option for your video.

Maybe you can include a (really) low res version of your video, maybe even in a smaller size for offline viewing.

Answer 2

Depending on your browser requirements you may find IndexDB as a possible solution to store files for offline access. IndexDB was designed to store larger amounts of data than localstorage.

Answer 3

You have to ask the user to increase the limit in the iOS settings. Check out the financial times web app and see their approach.

It's not very elegant to get the user to do it manually, but since there's no API, there's no real alternative (except PhoneGap, etc.).
