Video file formats?

LizzyB

Can anyone recommend preferred file formats for the Processing 3 Video library? I am running some tests in H264 and playback is choppy. I know that format makes a huge difference. Does anyone have experience or knowledge in this area? Which formats play smoothly?

I'm just messing with this very simple code from one of the examples right now:

  import processing.video.*;
    Movie myMovie;

    void setup() {
      size(1920, 1080);
      background(0);
      myMovie = new Movie(this, "temporaldraft.mp4");
      myMovie.loop();
    }

    void draw() {
      image(myMovie, 0, 0, 1920, 1080);
    }

    // Called every time a new frame is available to read
    void movieEvent(Movie m) {
      m.read();
    }

Thanks!!

Let me clarify:

I am not having trouble getting the video to load, but at about 2 minutes in, playback becomes choppy. I am wondering if someone has tested the video player with different file formats and documented results.

try it without the resize on line 12. is it any better?

@LizzyB -- no direct experience -- and the fact that it gets choppy after about 2 minutes sounds like a buffer / cache issue, unless the encoded images are much more information-dense in your video at two minutes in for some reason....

Other than koogs suggestion to try image(myMovie, 0, 0); -- this may not help, but have you tried experimenting with Movie.frameRate()?

There are some comments in the Processing Movie.speed source code that might be relevant, although this is a shot in the dark:

// If the frameRate() method is called continuously with very similar
// rate values, playback might become sluggish. This condition attempts
// to take care of that.
