How to make VLC output RTSP from a Chinese Mosaic DVR?

Question

CCTV

There is a Chinese registrar (on a Hi3*** chip) that streams via RTSP.

The stream opens fine through VLC. There is a task to display several cameras at once from this registrar in VLC in mosaic mode. But there is no way to do it. If you specify a local file instead of cameras, then the files will be displayed as a mosaic, and there will be a void instead of the stream from the registrar.

VLC version 3.0.11 on Windows 7 Ultimate.

Here is an example config:

del all

new   bg broadcast enabled
setup bg input     "C:\drivers\mosaic.png"
setup bg option image-duration=-1
setup bg output #transcode{sfilter=mosaic{width=704,height=588,cols=2,rows=2,position=1,order="1,2,3",keep-aspect-ratio=enabled,keep-picture=1},vcodec=h264}:duplicate{dst=display}

new   1 broadcast enabled
setup 1 input "C:\drivers\rt.avi"
setup 1 option dshow-size="352x288"
setup 1 output #duplicate{dst=mosaic-bridge{id=1,width=352,height=288},select=video,dst=bridge-out{id=0}}

new   2 broadcast enabled
setup 2 input "C:\drivers\rt.avi"
setup 2 option dshow-size="352x288"
setup 2 output #duplicate{dst=mosaic-bridge{id=2,width=352,height=288},select=video,dst=bridge-out{id=1}}

new   3 broadcast enabled
setup 3 input "rtsp://192.168.0.26:554/user=guest&password=&channel=1&stream=1.sdp"
setup 3 option dshow-size="352x288"
setup 3 output #duplicate{dst=mosaic-bridge{id=3,width=352,height=288},select=video,dst=bridge-out{id=2}}

control bg play
control 1 play
control 2 play
control 3 play

I run the command:

"C:\Program Files\VideoLAN\VLC\vlc.exe" -I dummy  --vlm-conf C:\Drivers\mosaic.conf

Info about the stream from the registrar from VLC:


I tried different configs from the Internet, but I never managed to show the stream in the mosaic.

What is a mosaic? Do you mean multi-screen 3x3 or 4x4 or something like that? If there are no more than 16 channels, then the easiest way is to download the demo version of the Line and set up each channel of the Line for each channel of the registrar, and you can take both the first and second streams from the registrar - there will be a second stream in the multiscreen and the load on the computer will be lower , the first stream will be in full screen and the picture will be more beautiful. Just don't forget to disable the recording - it's on by default, but the demo version still won't let you watch it. No other restrictions
