I remember way back in the day when YouTube was still in a Flash Player, you had the ability to dynamically overlay link buttons and clickable areas over videos at specific times/area and it was a lesser used but nice feature. There were a couple of videos that used it to sneak links to unlisted bonus content but it mostly helped when something was highlighted and clicking it would take you to relevant info. Think you could also use it for spesific playback controls.

I'm scoping out a small project and think it'd be cool to have a video with simmilar basic interactions and even fire off some scripts at different parts of the playback.

Since Flash died, I can't think of any web player that let's you create this sort of dynamic overlay/interface or implement logic to the media playback. I know Adobe Encore can be used to make this sort of stuff for DVD menus and I used to make training videos with old software that did similar things. But I don't believe those files are easily web compatible without Flash.

I'm sure a front-end wizard can layer a transparrent canvas and player and script their way to the same functionality and more. Or maybe use a web game engine and build a UI over video playback. But I'm curious if there's any service or library that does it already and saves me from another abandoned side-quest.

Unless I missed something obvisous, the only similiar functionality I've found in the common player libraries are overlaying adverts at set points in the display and you just set the scale and frequency.

Hello,

I have quite some technical question and my DuckDuckGo-fu seems very weak on this one. I hope it is ok to post questions on Tildes, as it is not really discussion material... but someone can still learn and use whatever come from this.

I have Live Aid concert that I ripped from my DVDs and I wanted to merge the individual video files (there are four) into one long video. I'm on Linux and I'm used to ffmpeg in command line, though I do not know it that much. Each of the input videos has its own chapters and I would like to transfer those chapters into the final video as well. Preferably adding a chapter in between every input video.

I was unable to find if ffmpeg allows for something like that in a single inline command. I may have to export chapters from each input video and add them into one "chapter" file and redo times by hand on them and then use this file as "chapter" input when merging the videos, but all this is just a theory on my part.

Is there some FFmpeg expert here who has done something like that?
