Is it possible to insert a looping video in a UI?

The other issue with this approach seems to be that obviously the knob has a certain range, is it possible to 'loop' the knob from 1.0 back to 0 automatically so that my filmstrip appears to loop forever?

@d-healey I've found that but it doesn't seem to work, pasting it into hise in a blank project and filling in the filmstrip name etc throws an error

@LozPetts It was made in a really old version of HISE so probably requires some clean-up to run in a recent version

@LozPetts I looked at the code and here's the error code

        if(event.clicked)
        {
            // Store the current value for reference when dragging
            widget.data.downValue = this.getValue();
        }

replacing "widget" with "this" solves it

@ulrik tried to set it up as an animation with a very small sprite, 19 frames 50x50, and it works

here's the project:

@LozPetts i see, you dont need the whole loop, you can loop this using davinci smooth cut to around 2 seconds. Other way is to separate dark and reflections ij photoshop and play them at different filmstrip speeds so it looks like an infinite loop.

LozPetts

@ulrik Thank you! Thank works beautifully - I had a few issues but I've got it going smoothly and it looks killer. Thank you to you all.

RE memory usage, I cropped the dead space from the video when I converted it to a film strip, according to the image pool table it looks like it's using around 100mb RAM, much better than expected.

@d-healey Once again thanks for your help - is there a way we can update the documentation to reflect the fix above? Or can only Christopher do that?

How are you checking that?

@d-healey I saw in another thread you advised someone to check the pool to see how much memory the bitmaps were using (if I understood correctly at least!). Created a popup window, Image pool table, although looking at it now it might not be showing the full size as hise sees it.

d.healey

@LozPetts Perfect!

@LozPetts What software do you use to create the sprites?
I've searched for a simple application for Mac OS but I only found some online sites who had that service but the sprite sheet was always horizontal and I had problems using the "offset x" instead of y, I couldn't get it to work (probably some stupid writing error from my side)

So I tried another approach with png sequences and loaded all pngs into the panel, and used the

g.drawImage(images[index], [0, 0, this.getWidth(), this.getHeight()], 0, 0);

switching pngs instead of using the offset function.

Here's an example using 360 png files size 1920 x 1080, weight of 71mb
I scaled the display inside Hise to half the size.

It works quite well I think

But I would prefer to make sprite sheets so if you have any tip of software for Mac OS, let me know.

@d-healey I had forgotten this one, thanks David!

@ulrik That one didn't work properly for me so I use this:

https://www.cssportal.com/css-sprite-generator/

What I did to get this working was:

Trim the empty space from the video edges.
Convert the video to GIF - https://ezgif.com/video-to-gif
Extract the frames from the GIF as PNG files - https://ezgif.com/split
Convert all the PNGs into a filmstrip with the above CSS Sprite Generator
attach filmstrip to Panel in HISE.

{
    local widget = Content.addPanel(name, x, y);
    
    Content.setPropertiesFromJSON(name, {

      "height": HEIGHT OF SINGLE PNG,

    widget.setPaintRoutine(function(g)
    {

        var index = parseInt(this.getValue()*197.0);
        
        g.drawImage("filmstrip", [0, 0, this.getWidth(), this.getHeight()], 0, index * ???);

            this.repaint();

    });
    
    return widget;

const sprite = createHeadSprite("LOOPPANEL", X, Y);

//	timer for animation (FPS)
reg count = 0;

Hope that helps someone out!
