Trying to play animated gif

[ckng2000]

Hi. i am newbie to raspberry and led rgb matrix but i managed to runtext, other demo and also customize some ppm file with text and graphics and make it run. But when i try out your image viewer there is nothing display on my screen. I am using one panel 32 x 32. Can you take a look and advice what should i do? Thanks

pi@raspberrypi:~ $ cd rpi-fb-matrix/rpi-rgb-led-matrix/ pi@raspberrypi:~/rpi-fb-matrix/rpi-rgb-led-matrix $ sudo ./led-image-viewer myimage2.gif Read image... Assembling animation with 8 frames. Scale ... 32x32 -> 32x32 Preprocess for display. Display.

It looks good and should just work. So if it doesn't, maybe your gif can't be properly decoded ? Do other images using the led-image-viewer work ?

So far i have tried a few images (animated gif, normal gif, and jpg) all same. Or do you have any working gif that i can try? I use GIMP to scale the image and save as gif maybe that's why is cause the problem?

[hzeller]

You don't really have to scale the image beforehand, the utility does it itself. Literally all images I tried have worked so far, so something else must not be working.

Did you check the "Troubleshooting" section of the Readme? There can be problems if the sound subsystem is triggered, and maybe the multimedia parts of the image library do that?

Make sure that snd modules are not loaded by the kernel - The Readme section suggest how. On Jun 5, 2016 22:19, "ckng2000" notifications@github.com wrote:

I just follow your instruction step by step, did not realize there is a sound subsystem, will give it a try to disable the it. Will let you know the outcome. Thank you so much for the guilines and advice. Apprecate it.

Hi. Sorry to trouble you but i still have no luck making it work. I read through the README.md and there is no mention of sound subsystem/ snd module? I am referring to the 32 x 32 rgb led matrix panel by right there should be no coding related to sound in the demo right?

This is the section: https://github.com/hzeller/rpi-rgb-led-matrix#bad-interaction-with-sound It was only submitted a couple of days ago, so maybe you don't have it in your git copy ? Do a git pull to get the latest.

Sound is nothing this library does, but the Raspberry Pi might provide sound due to some other reasons; and the sound-modules might hog that piece of hardware infrastructure the rgb-matrix library is using.

Did it work ? Another thing what people have reported is when they use a GUI based distribution. I recommend to just use a Raspbian Jessie Light.

Closing for now unless there is new development.

Hi. When i did a lsmod in fact something does show up on the snd module. thanks for the detail module coding but as a beginner i don't know how to create the kernel module blacklist file. I did some reading on that part it ask my to install Virtualbox, Vagrant and kennel-o-matic from adafruit. I tried without success so i guess i have to learn more for now till i understand how to create the blacklist file. I really wanna thank you for the detailed instruction. Apart from the image viewer i did learn many new thing from you. Cheers

[hzeller]

The Troubleshooting section contains two copy-paste commands that should help with creating the blacklist file.

Managed to remove snd from lsmod but still cant get the image viewer working. I cut and paste my command over. On the top part when i try to display runtext.ppm its working fine but when i change directory to image viewer the command seems to be working but nothing show up.
