Failure to build on RPi OS Trixie

Reproduce the latest release build on Raspberry Pi OS Trixie using the reported arm-linux-gnueabihf-gcc command and compare it with a previously working version. Inspect the generated src/av/video/reformatter.c and the av/include paths around the SwsContext and sws_free_context errors; done means the package builds successfully on the reported environment.

Hello,

I've just tried to build the latest version on an RPi running Raspberry Pi OS Trixie. While previous versions of Sendspin-CLI built and worked fine, I am getting some error messages when building the latest release.

Cheers,
Bjoern
