Thanks. Could you please create a ticket on GitHub and also share the video file? Or share it probably with me.

#3

Thanks for the reply. It does it with the video file provided in the example (bunny), and also another one of mine. I used the sample project without changing anything, should I still provide my project or just post the issue on github?

#4

I created a bug report on Github [9237].

The Defold example project also crashes for me (Ubuntu), when run from the editor. It runs for a reported 3.91 seconds then crashes. The call stack includes references to:
extension-videoplayer-mpeg/build/x86_64-linux/dmengine
and:
example/player.script:36: in function <example/player.script:34>
This is:
mpeg.decode(dt * self.playback_speed)
If I increase the value of this parameter by *6 it does not crash.
However the video is very choppy, and after the first run through has sync problems.
