https://github.com/CCExtractor/ccextractor/pull/1479 ffmpeg 5 compatibility bug is fixed. I will be included in next release. So ffmpeg dependency should be changed on next release.

@OctopusET Package is now builded with ffpmeg4.4, until ffpmeg 5 compatibility.

What about building with ffpmeg4.4 package before ffpmeg5 compatible patch is merged?

@cihcsf Thank you for reporting upstream (https://github.com/CCExtractor/ccextractor/issues/1418).

As the compatibility with the new ffpmeg 5 will take time, and unless a workaround patch, I will probably change the build to disable hardsub extraction which does no depends from ffmpeg. This simply means switching from ./build_hardsubx to ./build

For information, here are my CI pipelines: https://git.lokizone.net/booloki/aur-ccextractor/-/pipelines .

@binhex Do you have some information on which version of ffmpeg you have on your system? Might be best to report this upstream on the GitHub repo so it can be looked at, and possibly put restrictions on it if needed.

Edit: On my system, with ffmpeg 5.0 it's not compiling either, the same error as binhex. IIRC CCExctractor was still working with 4.4. I'll open an issue upstream.

im getting an error building this package:-

error making: ccextractor

It looks like the available ffmpeg is “too new” and they (deprecated and) removed the 'codec' member from AVStream recently, in favor of codecpar, is this the cause of the error perhaps?.

@Taijian Rust and clang are indeed new build dependencies. I updated the PKGBUILD to move them in makedepends. I confirm upstream PKGBUILD is outdated: only version bumps are done since years.

@Taijian The upstream PKGBUILD is outdated in that case; CCExtractor started using Rust as of this summer for the CEA-708 implementation. The flag is conditional, but enabled by default IIRC.

Sorry, but why does this package pull in rust and clang? The PKGBUILD provided by upstream only has gcc-libs and tesseract in depends, why so much more here? Are these maybe makedepends?

I added 2 AUR packages for the CCExtractor flutter GUI : one for prebuilt binary (ccextractor-gui-bin) and one for the full building (ccextractor-gui), at your choice.
