Kind Request: Universal Screenshot Tool rather pi board specific #36

Closed 2play closed 2 years ago

2play commented 2 years ago

@AndrewFromMelbourne Hello I can see its using the bcm library for compiling/use on pi.

Would you kindly consider making a universal version screenshot tool?

AndrewFromMelbourne commented 2 years ago

There is a Universal Screenshot Tool in fb2png. The nice thing about rsapi2png is that it could capture GPU output. There is no longer support for DispmanX on the Raspberry Pi, so this tool is no longer of much use.

2play commented 2 years ago

Dear @AndrewFromMelbourne thank you for still checking and replying on the subject. I found a tool that does all I need on rockchip boards, not bcm lib dependent and works on x11, framebuffer and kms.

Hi, sorry for tapping into this topic 😄 Is there any tool that can now (on Pi that use latest raspbian 11 (or whatever is called now 😉 )) tap into GPU output and "grab screenshot"?

AndrewFromMelbourne commented 2 years ago

@saper-2 not that I know of. I have not been involved with Raspberry Pi's for a number of years. It would be best to ask this question in the Raspberry Pi forums.

2play commented 2 years ago

@saper-2 get this and compile it (very fast) put the binary to your path or copy to /usr/bin and it will create a snapshot of anything on raspberry. I dont recall is Ive tested on Bullseye version but if not i have another for you the screenshot tool would make jpg out or anything you are on (desktop, framebuffer, kms) https://github.com/info-beamer/tools/tree/master/screenshot if you dont know how to compile let us know

@2play thanks for info, looks promising, but I have problem with linking:

I did some google-fu and find somewhere that on arm64 might not everything compile properly (there is some issues with libraries or library paths). I'll try try armhf (32bit) raspbian image too. -- edited -- on armhf same. I tried tinkering with path a bit (for LD -L and -I but didn't work either...)
