Adobe Acrobat Pro - Video Loop Not Working in Rich Media Playback

Hello,

I am trying to add a looping video inside an interactive PDF using Adobe Acrobat Pro 2024.1, but the loop function is not working. Here’s what I have done so far:

✅ I exported an interactive PDF from InDesign (MP4 video embedded).
✅ I used "Add Rich Media" in Adobe Acrobat Pro to add the video.
✅ Playback Style is set to "Play Content in the Document" (not floating).
✅ "Enable When: The page containing the content is visible" is selected.
✅ Right-clicking the video does not show a loop option.
✅ I tried adding JavaScript via "Document JavaScripts" using this code:

function loop() {
    var media = this.getAnnots({nPage: 0});
    for (var i = 0; i < media.length; i++) {
        if (media[i].type == "RichMedia") {
            media[i].media.play();
            media[i].media.loop = true;
        }
    }
}
loop();

Even after applying this, the video does not loop. It plays once and then stops.

💡 Questions:

• Is there any setting in Acrobat Pro that enables video looping?
• Is this a limitation of Acrobat, or am I missing a step?
• Could this be a version-related issue?

I would appreciate any insights or alternative solutions. Thank you!
