omxplayer overlay

evroom

Hi,

There is MMM-RTSPStream too.
Meant to stream video for camera’s, but it works for every RTSP stream.
You can specify height and width, but the position is determined by the module position.
Overlaying other modules depends on the position of those modules, but there is nothing that can’t be done using the custom.css.
And you cannot get away with trial and error.
It took me a while to get it pixel perfect…

ok thats what I wanted to know :)
so there is basically no really nice way to read the pixels you have to do it try an error

btw anyone knows how to set loop? I already tried multiple of the node omxplayer applications. They all have a loop function (well using it just stops after one run anyways)

evroom

I just tried MMM-RTSPStream and it loops the video without any extra options.
You also could just try to add --loop after the URL of the video.
When lucky it will be used as an omxplayer option.

As omxplayer uses a fixed position, relative to the position of the module, it might need a bit extra fiddling.
But with MMM-RTSPStream and the module options

moduleWidth: 900,
moduleHeight: 364,

and the omxplayer options

width: 480,
height: 270

you have the control over the overlay and overlapping that you need.
And with the custom.css you have additional options and control.

@evroom
Hm i Kind of fail to use it. When I use a config without url (I gave it a path to a local file)
showSnapsWhen paused is activated, I get this black window on the screen so the stream does not interfere with anything, however nothing is shown with omxplayer (autostartplay activated)
tried with mp4 and mov

so how do I properly use a local file then?

evroom

Can you try this config, just to know what works and what not ?

 {
    module: "MMM-RTSPStream",
    disabled: false,
    position: "middle_center",
    header: "Video",
    config: {
      autoStart: true,
      rotateStreams: false,
      moduleWidth: 900,
      moduleHeight: 364,
      localPlayer: 'omxplayer',
      remotePlayer: 'none',
      showSnapWhenPaused: false,
      remoteSnaps: false,
      stream1: {
        name: 'BigBuckBunny Test Stream',
        url: 'rtsp://184.72.239.149/vod/mp4:BigBuckBunny_115k.mov',
        width: 480,
        height: 270
    },
}

Height and width are perhaps a bit odd; is what I use for my camera streams.

I will look if streaming a local file is possible; never tried it.

evroom

For me this works:

url: '/home/pi/Videos/MoonEclipse.mp4',

So no ‘rtsp:’.
But I do not know if this sets the right parameters for this purpose, are more suited for CAM streaming I suppose:

|mm       | Starting stream stream1 with args: [
1|mm       |     "--avdict",
1|mm       |     "rtsp_transport:tcp",
1|mm       |     "--win",
1|mm       |     "33, 620, 513, 890",
1|mm       |     "--live",
1|mm       |     "--video_queue",
1|mm       |     "4",
1|mm       |     "--fps",
1|mm       |     "30",
1|mm       |     "/home/pi/Videos/MoonEclipse.mp4"
1|mm       | ]

Makes my Pi very slow too, but that is because I put the file on the SD, which is not a fast medium in my case.

ty I will try it

Ok I tried. Your first config worked perfectly fine when I tried and it showed me the video. However when I just swapped the url with a file path the way you said in your last post the omxplayer does not open it

@maxbachmann
I am just wondering…did you downgrade your electron to avoid activating openGL?
With openGL activated omxplayer ist not working anymore. Or did I get something wrong.
Sorry, it is not an answer for your question.

Thx
Mr.Coffee

maxbachmann

Hm no I did not downgrade electron. I am really not that deap in the topic, but why does electron stop omxplayer from working? (at least in my case omxplayer still works, although it kind of does not work with local files for me for whatever reason)
