Ristretto - Sub one second slideshow

xfce version = libxfceui-utils 4.11.1-2ubuntu1
Ristretto version = 0.6.3

I'm in the midst of replacing the Windows OS with X-UBuntu with some pretty great results. I notice the default photo program appears to be Ristretto which is *SO CLOSE* to fitting something I do.

I have a camera that sends pictures to a server whenever the motion control is tripped. Mostly I use it when I'm on vacation so I can see that my cat's still alive and his food & water is OK. I usually download the pictures, (Which tend to be around 1100 per day) then look at them. Before I used Photoscape to stitch them together in an animation and can specify that the time between each picture should be .2 seconds. Then I get 5 frames per second which is quick enough for me to go through them all in a reasonable amount of time but not so quick as to miss something.

Any way to get Ristretto to go into the sub-one-second level on the slide-show?

I can put the cursor on the forward arrow and click real fast and it keeps up better than Microsoft's picture viewer, but 1000s per day's going to wear out the mouse clicker.

Re: Ristretto - Sub one second slideshow

gThumb allows you to set the slideshow delay to .1 second (possibly shorter), but on the laptop I just tested it on, the interval did not appear to be that short (YMMV).

That's exactly what I was looking for! .2 seconds is fast enough.

Thanks!

Re: Ristretto - Sub one second slideshow

This ffmpeg command converts images to video. Image dimensions, fps, image type, and output format can be changed:

ffmpeg -r 5 -i aa%04d.png -vf "scale=min(3360/iw\,1080/ih)*iw:min(3360/iw\,1080/ih)*ih,pad=3360:1080:(3360-(min(3360/iw\,1080/ih)*iw))/2:(1080-(min(3360/iw\,1080/ih)*ih))/2" output.mp4

[-r 5] this will show 5 images per second.
[aa%04d.png] this is the image filename, with a numbering scheme (aa0001.png, aa0002.png, etc). you can use most common image formats.
[3360] this represents the width of the images.
[1080] this represents the height of the images.
