I've created a video player for an exhibition in a museum. The project is to be converted to .apk in order to be played on Android Tablet. I export to debug unsigned .apk sent to wifi to the tablet and thus I don't need to go via Play store.
Everything is fine so far. the video plays correctly. Except for a function I added to spped up the video onward and backwards . The function works as when a sprite box on screen (for backward/forward) is taped, 2 seconds are added or substracted to playbacktime.
This works great in preview mode and online but from the apk on tablet, Set Playbacktime function just restarts the video from the beginning.
I've tried with ogv and WebM sources and they just don't show on screen. Mp4 seems to be the only format playable from apk.
Any idea on how I can solve this ?
