[play Movie in processing] sound could be heard but no video shows up

Hi everyone, I have a video to play in Processing, but only could hear the audio, the video cannot be seen. There's an error log: JNA: could not detach thread

my processing version is 3.3.6 and I'm using Mac OS. The movie file is .mp4, size is around 4M.

Thanks in advance!



  • Problem solved;) Turns out I didn't put image(videoname,0,0); in draw function.
