led-image-viewer

[Camarg03]

Thank you very much in advance for this extraordinary library, I have managed to image a 64X64 matrix and it looks spectacular but I can't get the "video-viewer" to work, I think I have correctly converted the video to webm and it seems that everything is correct but I don't get the image with this code

sudo /home/pi/rpi-rgb-led-matrix/utils/video-viewer -f --led-rows=32 --led-cols=64 --led-parallel=2 --led-chain=1 --led-multiplexing=1 /home/pi/images/myvideo.webm -F -f

when I exit I get this message:

^CGot interrupt. Exiting
Total of 310 frames decoded

Greetings,

I note, you're not using the --led-slowdown-gpio option, use it if you have a Raspberry Pi 2,3,4. Then, bellow a link with a video, I'm using in there a 64x32 RGB Panel, with an Electrodragon active interface (regular) and a Raspberry Pi 3 B+ with Raspbian Buster. I just compiled within "utils" directory the image and video-viewer, and test video-viewer is running just fine.

Add the --led-slowdown-gpio =4 ( or 3 ) missing in your command and try. Share the output of YOUR panel

Ok, TRY THIS also, before you try with the sudo ./demo .... command

try to build from ZERO the all library:

1. make clean
2. make all

all this (1 and 2) from the folder rpi-rgb-led-matrix/utils/; so, you re-build (if it is not already builded) video-viewer and image-viewer. Check, the amount of memory for GRAPHICS... from raspi-config
