"CMake Error at deps/libimobiledevice/CMakeLists.txt:2 (cmake_minimum_required): Compatibility with CMake < 3.5 has been removed from CMake.

Update the VERSION argument <min> value. Or, use the <min>...<max> syntax to tell CMake that the project requires at least <min> but has been updated to work with policies introduced by <max> or earlier.

Or, add -DCMAKE_POLICY_VERSION_MINIMUM=3.5 to try configuring anyway."

I fixed it : Update deps/libimobiledevice/CMakeLists.txt line 2 to: "cmake_minimum_required(VERSION 4.0)"

It looks like the plugin is now finally broken, with OBS 29 and the new FFMPG. I currently don't have the time to look into it but I guess it could be fixed by applying a patch similar to this one here: https://github.com/obsproject/obs-studio/pull/8376/commits/1603aaf4a2ef16b7aabb3cf330c7b3fde77ad8ca

I just checked

#if LIBAVCODEC_VERSION_MAJOR < 60
    if (decode->codec->capabilities & CODEC_CAP_TRUNC)
        decode->decoder->flags |= CODEC_FLAG_TRUNC;
#endif

on line 41 in (obs-ios-camera-source/src/ffmpeg-decode.c) works to make it compile and work again.

Here is the patch needed to build. For now you have to use a specific tag of the obs-studio repository until the author adjust to the new mechanism.

Note: This command specifically gets version 27.2.1 of obs-studio because the libobs import mechanism for plugins changed after that version. In the future, this plugin will be updated to use the new method.

Hey there, thank you very much for taking a look at it! This is just a little bump for you :)

@Greaka thanks for telling me about this, I don't use the package myself, so I don't pick up on problems like this.

I might have a look at it tonight, but I have quite a large amount of work as I am taking GCSE exams in a few weeks so it might take me longer to get to. If it is not fixed by the end of the week, please bump this again :)

Please excuse if the inline HTML fails, this is my very first AUR comment.

The build fails for me with the following error:

How can I fix this? libimobiledevice is already installed, openssl works fine for other programs to compile, too.

@davd I have updated the package. I cannot test it myself as GitHub has been blocked on my campus (and VPNs, proxies, Tor e.t.c. are all blocked along with a nice smothering of HTTPS MITM). If it fails to build please contact me ASAP

Thanks for making me aware of this. My laptop is currently borked so I will try to fix this as soon as I get my laptop working again

After reviewing the fix, it seems like the removal of avcodec_register_all() is not needed anymore since it does not exist in the mentioned area anyway.
