Super weird image on videos via VLC

[donlombardo]

Pi Model or other hardware: 4B
Power Supply used: Powersupply that I bought with a Rpi case, 5.1V, 3A
RetroPie Version Used: Buster 4.8
Built From: download from retropie website
USB Devices connected: USB keyboard

I have a fresh install of RetroPie, latest version, on a RPi 4 B, and running VLC gives correct audio, but a very weird image (see picture 1). If I take a screenshot, it's alright (see picture 2). I have no clue what the problem might be, I have never seen this before or any Raspberry Pi. I have never tinkered with VLC either, so I don't know where to start. What kind of troubleshooting can I do?

I have it running via composite out, but I've tried it with HDMI as well, and it's the same.

Linux 5.10.103-v7l+ armv7l GNU/Linux

Config file:

# For more options and information see

# Some settings may impact device functionality. See link above for details

# uncomment if you get no picture on HDMI for a default "safe" mode
#hdmi_safe=1

# uncomment this if your display has a black border of unused pixels visible
# and your display can output without overscan
#disable_overscan=1

# uncomment the following to adjust overscan. Use positive numbers if console
# goes off screen, and negative if there is too much border
#overscan_left=16
overscan_right=-16

# uncomment to force a console size. By default it will be display's size minus
# overscan.

# uncomment if hdmi display is not detected and composite is being output
hdmi_force_hotplug=1

# uncomment to force a specific HDMI mode (this will force VGA)
#hdmi_group=1
#hdmi_mode=1

# uncomment to force a HDMI mode rather than DVI. This can make audio work in
# DMT (computer monitor) modes

My guess is that the VLC version included is the one from Debian and not from the RPT repositories (which is patched to handle RPI's VPU).

Try using omxplayer or installing kodi to view videos, they should take advantage of the HW video acceleration present in the RPI's GPU.

@mitu Thanks, I'll try that!

omxplayer worked with the video! Thank you. I tried uninstalling VLC and installing again, same result. Thanks for the help!
