Thank you,

Hi, @veetek22

Have you installed the latest Libcamera-DEV, which is the 0.0.8 version.

As the naming space where AFTRIGGER is located in the latest Libcamera has changed, this problem has occurred.

I’m sorry to bring you trouble, we will repair this issue as soon as possible.

[veetek22]

Yes , libcamera-dev is at version 0.0.8

anything I can do to fix it ?

what are my options ?

[veetek22]

Good Morning @yang , anything I can change in the files to make it work ?

It is occurring in the same part of the code

[rsmith9945]

@yang, If I implement the suggested change, it solves that error, however I encountered a new error:

/home/pi/mjpg-streamer-libcamera/mjpg-streamer-experimental/plugins/input_libcamera/input_libcamera.cpp:71:5: warning: invalid suffix on literal; C++11 requires a space between literal and string macro [-Wliteral-suffix]

EDIT: I made the changes suggested in this post https://forum.arducam.com/t/problem-compiling-mjpg-streamer-on-buster/2737 and I was able to compile!

@rsmith9945

are you work now?

[rsmith9945]

Hello @Edward, yes after installing the recommended octoprint version, and following this guide, I was able to get it to work! I am using a raspberry pi zero, so my camera stream kept freezing so I had to make a change recommended in this article Webcam freezing after a few seconds - Webcams - OctoPrint Community Forum and now everything works perfectly!
