I use a Galaxy Note 4. To get 'live shots', a few months ago I downloaded the app Camera MX. I just received an OTA update to Marshmallow, and now every time I try to view live shots created before the update I get the error: "Can't play this video".
So far, I've found that the app stores the video clip that comprises the 'live shot' as a standard .mp4 video clip in a hidden folder '.LiveShot'. I've tried to find some sort of file that maps the .jpg pictures to the corresponding .mp4 in the .LiveShot folder, but I can't seem to find anything. I even used exiftool on the .jpg files to see if it was embedded somehow, but exiftool doesn't see it. Is there some sort of fix out there for this problem?
