Library_avmediaQuickTime is preferred over the Library_avmediaMacAVF. Did we update the build bots to newer Apple SDKs around Jul 30 2017, or even a newer OS? I had a glance at the MacAVF plugin. All this AVPlayer based stuff is supposed to be handled async. My guess is the caching is simply not yet ready, when we try to take a screenshot for the preview image. Actually I don't see any real handling of the async "playable" or other status. Don't have really time to fix this, but a lot should be handled async, and there is just a minimal observer, when playback stops - as I understand the code.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
