I belive than its something related to thei "osg-ffmpeg-videoplayer" than crash only on arm because of alignment date error than on x86 doesn't happens. thats statement its based on my google searching skills... but of course, I am a noob. I updated my ffmpeg to the latest version but that doesn't solve the issue (than I think its related to arm platform on memory management when appears data alignment problems) If the game want to play a video ffmpeg calls to crash handler. I will upload my error log. -- Ticket URL: <https://trac.ffmpeg.org/ticket/7766> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
