I'm trying to overlay a logo in vlc on my RPi (Bullseye) but when I add the logo using:

cvlc -v --random --loop --fullscreen $xid --video-filter "logo{file=weather.jpg,position=1}" playlist.xspf

I get these weird error messages. From what I understand the hardware decoding in vlc is a hack (aka custom vlc version) - is that the reason for this blending routine error?

You need to disable hardware decoding acceleration.

You need to disable hardware decoding acceleration.

Thanks - but that's too bad - is that a limitation on the RPi version (MMAL renderer?) or VLC in general? The text overlay works perfectly with hardware acceleration though.

It is a limitation of video filters, as opposed to overlays. If you don't care, you can use the logo overlay.

No, I definitely don't care - so I guess I should be using sub-filter logo? I had not realized these were different.
I tried

Code: Select all

cvlc -v --random --loop --sub-filter logo --logo-file weather.jpg --logo-position 1 --no-video-title-show --no-audio $current

but the logo doesn't show up and there is no error either in the log. Am I missing something?

You seem to be using a VLC build with third party modules and changes, so :shrug:

Hi, it is the default vlc downloaded from raspberry:
Raspberry Pi OS with desktop and recommended software
Release date: January 28th 2022
System: 32-bit
Kernel version: 5.10
Debian version: 11 (bullseye)

without any modification. So I can try to uninstall vlc and install?

Posted: **25 Feb 2022 19:51**

All I'm saying is that this is not the VLC released by VideoLAN.org, so I don't know the details how yours behave.

Hi, it is the official download from

Code: Select all

sudo apt install vlc

From what I read in the rpi forums - they did customize vlc so I suspect Remi is right.

Hi,
I try to set the logo in the GUI interface and set bottom-right. So next I try to launch vlc from command line...
a simple

Code: Select all

cvlc -f video.mp4

now if I do ALT+C and ALT+F the logo appear. I try to search what I do so
ALT + C = Crop one pixel from the bottom of the video
ALT + F = Crop one pixel from the right of the video
and the logo appear on the bottom right.

So how can do this in command line? There is no problem with the logo but only the right command. Thanks

but it doesn't appear.

why?

thanks
