hi ,trying to use this module to watch an ip cam.After i start MM i get in the log:

Starting stream stream1 with args: [
    "--avdict",
    "rtsp_transport:tcp",
    "--win",
    "738, 63, 1090, 305",
    "--live",
    "--video_queue",
    "4",
    "--fps",
    "30",
    "rtsp://admin:@192.168.1.108:554/12?"
]

Starting PM2 for omx_stream1
PM2 started for omx_stream1

when i press pause and play again i get:

]

I just get a blank screen.Steam is working nice with vlc,its the second low res stream of this camera.
config:

    module: "MMM-RTSPStream",
    position: "top_center",
    config: {
        autoStart: true,
        rotateStreams: true,
        rotateStreamTimeout: 10,
        moduleWidth: 354,
        moduleHeight: 240,
        localPlayer: 'omxplayer',
        remotePlayer: 'none',
        showSnapWhenPaused: false,
        remoteSnaps: false,
        stream1: {
            name: 'bibicam',
            url: 'rtsp://admin:@192.168.1.108:554/12?',
            frameRate: undefined,
            width: undefined,
            height: undefined,
            },
        }
}

any ideas?

That’s a new one by me… maybe time for Google on that one.

For the blank screen: watch all of the PM2 logs (pm2 logs command) and see if you see something like this:

1|omx_stre | * failed to add service - already in use?
1|omx_stre | /usr/bin/omxplayer: line 67: 15281 Aborted (core dumped)

If you do, you probably have the latest version of Raspbian with the OpenGL driver enabled in raspi-config– omxplayer isn’t working properly with the OpenGL driver enabled, if you want to use omxplayer, you’ll have to enable the legacy driver: https://www.raspberrypi.org/forums/viewtopic.php?t=204794

If you see anything else in the PM2 logs, let me know.

i tested the bunny rtsp and another camera that output a “rtsp://ipcamera:554/ch0.h264” link and both work,so i think the camera i want to use that output the “rtsp://ipcamera:554/12” link has a problem with omxplayer.I will look at pm2 logs and i ll get back to you,thanx
edit : the links that worked for me did not auto started but i had to press pause and play again.

pm2 log :

/home/pi/.pm2/logs/mm-out.log last 15 lines:

i see no error but no streaming,only the name of the cam and black screen…

I found that on my troubleshooting on the internet maybe that helps us?

Looks like you’re using an older version of the module based on the log. Try pulling the new version and switching to the develop branch… you should see the full omxplayer command line output to the logs, which you can use to test your camera outside of MM and the module.

Updated to dev branch and use rotate streams true (3) and after 3 hours it completely locks up my entire RPi and I have to pull the plug and disable same. Seems like it is too much on CPU to keep starting/stopping OMX every 15 seconds to cause the crash? Single stream average RPi temp is 128f but when rotate is on it jumps to 160f. Maybe thats the issue?

@swvalenti That could be. OMX player doesn’t switch very easily. VLC switching was working well on the newest version of Rasbian with OpenGL (Fake KMS) enabled.

How do I make that switch and implement? Sorry for the noob question.

Thanks for the link. Bits of that script look like the script I saw which originally inspired me to use omxplayer, but it has some additional options (like pushing a video off the screen instead of stopping it) that seem promising. I ended up using pm2 instead of screen because that’s what most MM users were already using, and it had the auto restart feature built in.

I don’t have much time for the next month or so to keep playing with the omx version, so if you wouldn’t mind, please open an issue on GitHub, and if you or anyone has time/skills to implement, I’ll be happy to take a PR.

To-do (notes to myself or anyone that works on this):

Implement dbus control to move the video off-screen instead of stopping it when we need to hide it: Example dbuscontrol.sh; npm dbus Package
Implement ffmpeg & vlc’s shutdownDelay option for omx player (e.g. move the video off-screen and stop it after x seconds instead of stopping it immediately when hiding a stream).

Look back at previous posts in this thread, there should be several posts from the past month about switching and upgrading.
