Color display mp4 conversion failed

I am trying to convert an mp4 video to pqoi, and I get an error in terminal

Can someone help with this?

A single png to pqf worked fine. Maybe it has to do with the input file? It is pretty large resolution (but not really file size) mp4.

I tried to re-make and install netpbm, as I thing it was the old one on unbuntu.
I got this error at the end:

so maybe its related to the netpbm install.

edit - I am pretty sure I now have the latest version of netpbm, and I get the same error in pqoi.

This looks like a problem.
Did you install “mjpegtools” ? (with apt)

That’s seems to be it, thanks!

Also, I did not see a reference to installing mjpegtools anywhere, unless it just a linux thing I should have known. I am a little familiar with linux, but haven’t used it a lot.

Now, in order to just have this pqf loop on a display, All I need is to do is put it in the folder WxH with the scr file WxH/idle.scr? (where WxH is the actual dimensions of the file/display)

I added it to the list.

You can put the PQF file anwhere you want, as long as idle.scr tells ProffieOS where it is. Whether it is looping or not depends on how you made it. Normally when you just give cpqoi a single image or movie, it will always make it looping.

Note that you can use dpqoi to inspect the result, just make sure you run it in a new, empty directory as it will produce a bunch of PNG files from the PQF file.

More info about SCR files can be found here: ProffieOS/display/layer_controller.h at 9ec9367a31c39ec7d67f1b358450d46402930699 · profezzorn/ProffieOS · GitHub
