HTML5 offline video caching in mobile safari

Question

I can\'t seem to get Safari on the iPhone or iPad to offline cache videos. Everything else gets cached just fine when I go offline. The video file is obviously in the mani

Answer 1

Sadly there’s a ~5 MB limit on offline cache in Mobile Safari. Not much you can do about it.

Answer 2

Audio & video are not cached by iPhone since they are played by external applications. It seems the only workaround is to store them as base64 in local database or have them cached in application manifest as php(or similar) file but with base64 encoded audio and video content.

Answer 3

Perhaps something like this would work: http://www.nihilogic.dk/labs/jsvideo/test2.php

Answer 4

i have read it needs an html5 manifest setup to cache files

Answer 5

Update for iOS 4.3 on iPad:

I just tried adding a movie to a manifest file in iOS 4.3.

Safari asked me to allow extending the offline storage and then downloaded the movie.

Answer 6

See these two articles for mobile browser cache limits (note that the second one adds vital information):

It only generically covers html and "external resources", but they didn't explicitly test video files, so maybe these are never cached by Mobile Safari.
