Hi devs! the open morrowind devs find out than my crash on openmw was caused by ffmpeg (libswscaler?). 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.

  • Keywords Invalid address alignment arm raspberry removed
  • Priority changed from important to normal
  • Version changed from 4.1 to git-master

This sadly has no similarities with a valid ticket. I hope that you understand your comments elsewhere don’t make me feel like investing a lot of time but please test current FFmpeg git head, the only version supported here, and provide backtrace, disassembly and register dump for the crashing thread (not necessarily for all threads except the crashing one) as explained on

Is the crash reproducible with ffmpeg, the application?
