Manage omxplayer and its video layer on Raspbian/Raspberry

While omxplayer is playing a background video on the raspberry/raspbian I need to show another smaller video over it, practically I need to manage a second instance of omxplayer over the first instance while it is already playing in fullbackground. Attached you can find a demo of a layer with numbers, for now I just need one number , not 3 like in this attached demo, and this number overlay video will go from 01 to 0 99, I am preparing it, here is a bad example going in the opposite direction and strange outlook: [login to view URL] I should give you a better video brackground and video overlay into few days. The software should be done using the latest version of lazarus and freepascal for raspbian or any another else like a sh script. The Raspbian version is the last stable. 1) at every left click of the mouse, the video in overlay (the counter video) stop to be in pause and it goes for PLAY for N seconds, then it go back again in pause for [login to view URL] seconds 2) at every right click of the mouse, the video go to the next chapter (it should be doable trough the KEY BINDING: O) if it is a big trouble with it, you can also close and reopen omxplayer, but only if it is impossible you cna take this other way: close and reopen omxplayer, but it makes the .mp4 video in overlay to disapepar for about 0,5-1 second, and this is not nice to see, and it is a limit that omxplayer can't change, cause of the little resources of raspberry. 3) screen size of the backgroudn video and raspbian configuration: fullhd portrait and landscape: 1920x1080 and 1080x1920. 4) the configuration must be done trough a file [login to view URL] saved into the raspberry that save these data: A) define on which layer to show the mp4/video in overlay B) define the position and dimension of the video in overlay C) write the name and path of the .mp4 file in overlay D) define in how many seconds [login to view URL] (with the precision of the 0.1 seconds) the playing should reach the pause after every left click of the mouse Demo code of the layer of omxplayer launching a second instance over another omxplayer playing fullscreen: A videos is fullscreen and B videos is using the top right side of the screen showing the B video over that part of the A video. omxplayer --no-keys --layer 101 --win 1200,100,1840,460 [login to view URL] other informations in the forum of omxplayer: [login to view URL]
