led-image-viewer doesn't work. "Crashes"?

[Cyb0rk]

Hi there,

I compiled led-image-viewer and tried it on several gif images, but all I get is the following output:

pi@autopi ~/display16x32/rpi-rgb-led-matrix $ sudo ./led-image-viewer giphy.gif
Read image...
Assembling animation with 25 frames.
Scale ... 281x216 -> 32x32
Preprocess for display.
Display.

Its runs for about half a second on terminal and than terminates. And nothing is shown on the panel. Rest of the examples work fine!

Any Idea?

Can you attach the image that is breaking ?

[Cyb0rk]

Of course, here are two of them.

P.S. I would like to use led-image-viewer only to display static images, not for gifs. But even pngs etc. don't work

I'm having this same issue. Tried all sorts of image formats, sizes, shapes, etc.

I get the below every time just with the scale line changed to match whatever image I'm trying to use.

Read image...
Scale ... 500x32 -> 32x32
Preprocess for display.
Display.

Nothing on the display, not even a flicker. Program exits and I'm left with the command prompt.

Raspberry Pi 2 B v1.1
Running fresh install of Raspbian
Debian Wheezy
Release date: 2015-05-05
with all dependencies listed in your readme installed. Nothing extra over a default install.
4GB Class 4 SanDisk Micro SD card

./led-matrix runs perfectly with all included demos and any correctly formatted .ppm image

Should be fixed now, can you try again ?

[artictriac]

It is now working for me. Thanks for fixing it so quickly.

That fixed my issue but now I cannot get the display to stop without killing the process

Ctrl-C doesn't work ?

Yes, they are inconsistent. The other demo programs don't get shut down
properly on Ctrl-C, they do return.
I'll make these conistent soon.
