I am trying to have multiple videos play at once when "publishing online" in Indesign. But when I publish, and open in internet explorer or firefox, the videos play one at a time. I have the videos set to "play on page load" and "loop". But only one will play at a time. I am trying to mock-up what our website will look like with many videos playing at once. They are small mp4 files.
Did you link them in the Timing panel so they start at the same time? (Open the Timing panel, select all videos, and click on the Link icon at the bottom of the panel)
I just tried to link them, and now neither one is playing on page load. I have to push "play" on the video for them to load. Then when I press "play" on the other video, the first one stops. All of my links are set up to play upon page load and to play together. I have no idea why it's not working.
You're right. The two videos play fine together in the Preview panel in InDesign, but not in any broswer. That reminded me that most browsers block Auto-play by default. Since you cannot control the viewer's browser setting, you cannot rely on Auto-play (Play on page load), even for a single video. Sorry I didn't think of that earlier. I know it's not the answer you wanted, but I'm not sure this can be done with InDesign and Publish Online, given the setting in most browsers.
I have the same issue. I have 5 smalls mp4 files that dont automatically play. You have to push the play button on each to get them to play their loops. Such a bummer.
