Re: Video Playback

Te last time I did a video was on 1.2 with something I downloaded from you tube.  That was fine.  This is something I've recored and exported as an mp4 - the video plays fine copied to the phone its only when playing through openspace that's causing the slowdown and judder

Re: Video Playback

Maybe you can try to compress and reduce the video size and mp4 format using VLC.
Issues with frames judder can also be caused by the audio sync. you can try different audio formats.

Re: Video Playback

converting to the file to an android optimised HD file seem to do the trick.  A little sync issue but good enough.  Thank you
