Hey, thank you for sharing this Gist. It's leading me to the right path. I am encountering some instability with 3 of my Eufy cams running RTSP. Ignore camera 4. I have commented that one out because it's a trash Wyze cam of little importance to me that will be replaced soon by another Eufy. Final version desired is to have 4 RTSP cams displayed on a 1920x1080 display evenly divided into 960x540 per cam. Below is my running file at the moment. Stream #1 does a good job at staying stable with zero flicker while stream 2 and 3 begin to flicker quite a bit. Note that all of these streams run completely stable when I run a direct network stream in VLC individually so I feel like VLC is struggling somehow with the mosaic. Here's a clip on Imgur The background image is of my dogs and as previously mentioned, don't worry about the 4th stream not appearing at all. It's commented out right now.

Anything stand out to you in this file? What about VLC settings? I've tried running this with both hardware acceleration off and on in VLC.

Thanks I got mine working. Anyone know how to hide the second VLC window?

I signed up for an account just to comment on this.

I have (4) Hikvision cameras and wanted to display them on a 1920x1080 monitor. I also wanted it to be as idiot proof as possible, hence why I'm looking at this route rather than using the full ActiveX client.

Anywho...

One important thing I think is overlooked, is the size of the initial background. In my case, I made a .jpg file in Paint the same size as the screen, 1920x1080.

I also tweaked some of the above config -- and it seems to be working great.

To be run with: vlc.exe --vlm-conf C:\Temp\test.vlm -I dummy --no-video-deco --no-embedded-video

Also note -- I run this with "vlc.exe --vlm-conf C:\Temp\test.vlm -I dummy --no-video-deco --no-embedded-video" -- as this eliminates any additional pop-up windows/title bars/etc. -- just a screen with 4 cameras.

Note: The bolded statements just happen to begin with a # as they are commented out. Not sure why that happened, but, YOLO.

Hi Vankalif how are you?

I do it like what wrote.. and still I didn't get anything in my VLC 3.0.18.
You have an option to check it with me?
Big thanks

@elirannat do u read the comment @noparking247 ? Have you tried?

Try this as example, before you start, you need an image with 1920x1080 size in pixels. Place it in "C:\Temp", name it bg.jpg
Hope it will help you!

Still not working to me Nicolay.
Please advice..
I can provide you remote access to check it.

Thank you & best regards,

Yes I read it.
Not works.

That's not overly informative. What doesn't work? Do the feeds work in VLC to begin with?

The streams you referenced appear to just contain audio... so... I'm not sure what you're expecting.

@Vankalif @noparking247 Firstly, thank you both for sharing your VLM files - they've been very useful for me to get my video streams operational. However, I'm experiencing a choppy and jittery video stream in mosaic.

I am currently running 14 cameras, each with the following specifications: 1440x1620 resolution, H265 encoding, 10 FPS, 1 sec Frame Interval, and 1024 Bitrate.

The VLC machine is a 1440p with hardware decoding enabled (Direct3D11 Video Acceleration) and running with an RTX 3090.

Although I can open all streams individually, they become choppy and jittery when combined in a mosaic. I suspect this issue may be related to the encoding options in the VLM file. Right now, the VLM file is set to mp4v for the encoding while my IP cameras encode in h265. I tried to change the vcodec transcoding settings to vcodec=h264, vcodec=h265, and vcodec=hevc in the VLM file, but the video just won't start without the vcodec=mp4v.

Would greatly appreciate suggestions or feedback on this. Is there a specific encoding option that I should use for h265 encoded streams or could there be another potential solution that I may be overlooking?

Here is the VLM configuration that I have been using:

Please anyone can help me with 16 Camera, I need a script with 1920 x 1080 and 16 Camera

@F-AlFaris that doesn't really surprise me. I had similar results when I was using the main stream of my cameras (with similar configurations). I ended up switching it to the substream feed, which looks fine when it's small anyway. In my case with Hikvision cameras, this was done by appending the "/Channels/101" to the path -- each vendor will be different.

I also noticed that VLC has a memory leak when using mosaic. If I used the main feed, I'd be lucky to have it working for more than an hour. With the substream, it works for ~24 hours. I ended up writing a small script to run every 5 minutes to check to see if "vlc.exe" is consuming more than 2GB of RAM -- if it is, forcefully close it, and relaunch.
