Ghost Overlay / OMXPlayerTransparency

Please give some more detail on how you put this together! I have tried to do it for quite a while but the video is always choppy and does not look good. And what hardware are you using, I assumed my Raspberry Pi was just too slow for video…
And can you share the Ghost video or let me know where you got it?

@Reotch2 Have you tried to make the position of the module behind the modules, or play it as a background? So the other modules is on top?
In that case you dont need any alpha.
Position the module with OMXPlayer:
fullscreen_below

Also this module may help with that, if you could trigger the module with PIR:

@nobita @jasondreher So… I’m not what they call a “coder”… haha. I wish I knew how to write javascript, but the best I can do is re-purpose everyone else’s modules. Put simply, I looked into using an I-Frame, or MMM-Podcast, but had trouble referencing a local video file. After having NO success adding a video player module, I decided to run a transparent full-screen video on–top of the magic mirror page, which actually worked better than I hoped. Although the black portions of the video dim the modules slightly, the way the white portions interact with the modules beneath it adds a certain cool-factor.

After some trial and error… I did the following:

Bought the “Ghostly Apparitions” DVD at a local thrift shop. Amazon link
Combined the highest resolution vertical scenes into a single m4v.
Edited the node_player.js for MMM-PIR-Sensor to include omxplayer. This ensures that when the screen is activated, the video is played with the appropriate flags.
exec(“/opt/vc/bin/tvservice --preferred && chvt 6 && chvt 7”, null); exec(“omxplayer ~/Videos/Ghost.m4v --alpha 80”)
Alternatively, you can just modify the start script to continuously loop the ghost video of your choosing.

If you need any further details, feel free to ask. But again, I’m a tinkerer… and I’m sure there are 1000 better ways to do this, but this works for me.

@Nystro0m I’ll definitely give this a shot. I’m using a local file and previously had issues because of JS sandboxing. Not sure how I missed this module, this may be what I’ve been looking for. I’ll report back if it works.

@Nystro0m Is there a workaround to reference a local file? I’m running the same issue I did with MMM-Podcast.

@jasondreher Running a pi3, no overclock.

@Reotch2 I actually just was dealing with something similar trying to get that module to work as a background!

Right now I have just a picture instead, but it should be the same idea. Put the video file somewhere on the MagicMirror directory - my image is in the CSS file but it doesn’t matter where. That way it’s included in what’s accessible on MM’s webserver that it starts. That way, in the config, you can specify the URL for the file! On mine, the picture bg.jpg is in the CSS folder, so my file listed in the config is "http://127.0.0.1:8080/css/bg.jpg".

The biggest issue with this is that AFAIK it’s liable to get erased in updates to the MagicMirror framework, since I’m pretty sure the only two files that don’t get touched are config.js and custom.css. I’m also pretty sure that someone smarter than I has figured out a great way to get around that. BUt, since it’s just for halloween it’s probably temporary anyways so hopefully this gets you up and going.
PS that is a cool as hell idea!

@Reotch2 would be cool if you could package up what you have to share ;)

@Reotch2
Make it a .mp4 with a h.264 codec.
Make a folder in your module called videos.

videoSRC: "/videos/YOURVIDEONAME.mp4",
loop: true,

You could also try:
http://127.0.0.1:8080/modules/MMM-htmlvideo/videos/YOURVIDEONAME.mp4

If that don’t work. Put it on a fileshare somewhere.
Maybe drive or dropbox could work if the share settings is public.
