Normally in Lightroom, when you look at the video in Loupe mode (full screen) there's a play button/timeline that lets you watch the video.
But now, I just noticed that none of the videos have a play buttons anymore. Not sure if a recent update broke this function... anybody else have this issue?
In grid mode, video previews still work fine when I move my mouse pointer across them...
I have the latest Lightroom 2015.3 and I'm running Winows 8.1 (6.3.9600).
Thanks for the link... I followed the instructions and replaced the video_toolkit.dll file with the updated one and the play button is back now.
