Crop, Croppadd, Tearing, VSync, Video-Wall
Posted: 05 Dec 2017 09:45
Hello,
I tested the --crop and --croppadd Commands with the VLC-Version 2.2.6 (32-Bit) and the OS Windows 7 and also Windows 10 for a different Videowall-Solution.
My first Commandline-Example starting two instances of the VLC-Player with the same Video, but every Video will crop in a left an a right half.
The Idea behind is to use different Devices, which are connected in a local Network and playing the same video synchronic.
This could be an solution for a Videowall with different Devices.
Demo-Video (MP4, H.264, 1920×1080): https://www.so-geht-saechsisch.de/wp-co ... HD.mp4?_=1
The video is safed in "c:\Temp\Life-is-a-dance.mp4".
Commandline Example:
CMD-Example (*.bat) in Text-Form:
@echo off
start "" "C:\Program Files (x86)\VideoLAN\VLC\vlc.exe" :file-caching=320 --no-video-deco --no-embedded-video --video-x=1 --video-y=1 --qt-start-minimized --no-video-title-show --video-filter=croppadd --croppadd-cropright=960 "C:\Temp\Life-is-a-dance.mp4"
start "" "C:\Program Files (x86)\VideoLAN\VLC\vlc.exe" :file-caching=300 --no-video-deco --no-embedded-video --video-x=960 --video-y=1 --qt-start-minimized --no-video-title-show --video-filter=croppadd --croppadd-cropleft=960 "C:\Temp\Life-is-a-dance.mp4"
Commandline Example with 4× VLC-instances, 4× cropped video and --netsync Command:
CMD-Example (*.bat) in Text-Form:
@echo off

On all the video borders from --croppadd Command you can see more or less tearing.
In the Example-Script with 4× VLC-Instances I have to use the --zoom=0.5 Command for the correct Video-size.
Are there any Ideas to synchronize the Video with Vsync or other solutions, to avoid the tearing?
I'm not shure if the --netsync command works?
Any Ideas for synchronization?
Thanks,
Thomas
