slideshow with pygame

Hello

I have a button which is active-high and i want to display a slideshow out of 4 pictures when the button is pressed. The first three pictures should each be displayed for 3 seconds, the last should then stay there until another button is pressed. Is this possible with pygame?

thanks

If i use the same terminal window again to start the script/video again, it won't stop, but if i open a new terminal and start it, it works again. Plus in t...

I've seen the thing now with the MPEG2-license that i need to buy. Is there no other way to do it?

Re: Showing an image with gpio

I've created this little test script for detecting the duration of the press and then show image 1 or image 2 based on the time the button was pressed. It doesn't create any error but it still won't work. Any idea? Maybe theres something wrong with the identation, but i can't figure out what exactly...

Re: Showing an image with gpio

Thank you for the hint about the videos and the sleep, i will try it. I'm a little bit unexperienced at python programming, what do you mean with GPIO Callback and why is it a problem if it does the block over and over again? And with which term should i search about the long-press code? is there a ...

Re: Showing an image with gpio

I modified the script, it works now the way i want it. I just have the question if i could make it more efficient and if there are some useless lines i've written. Keep in mind that this is only a test with 2 buttons, but the final script should have 10 buttons in it. So maybe there is an easier way...

Re: Showing an image with gpio

So isn't this possible with imagemagick or the default image viewer of raspbian?
pygame looks a bit more difficult than the stuff i did so far, or am i wrong?

Re: Showing an image with gpio

Thanks guys, your tipps worked. Now i have two more little questions: 1. What command do i need to display the picture in imagemagick in fullscreen (without any toolbars and things) and without the little "pan icon" window? 2. I have two pictures that should be displayed. Which command do i need to ...
