This should probably be a short GSoC project.
Indeed FFmpeg changed their API a lot (to the better, I must say), so this is not going to be something we can fix in one evening.

Just ran into that issue. Came here.

The av_register_all() function has been listed as deprecated since ffmpeg 4.0 in the official changelog, avcodec_decode_video2() seems to as well, later on.

@rhertzog commented on GitHub (Jul 5, 2022):

Hi, is there any plan to address this? Most distributions are busy to organize the switch to ffmpeg 5 and if ccextractor doesn't keep up, the package will end up removed. :-(

Thank you for your work on maintaining ccextractor!

I think it's happening or will happen as part of the hardsubx rewrite effort by @PunitLodha and @shashwat1002.

I've seen references to FFmpeg 5 there.

Yes, this will be a part of the HardsubX rewrite. While we are working on it, a short term solution would be to compile CCExtractor without HardsubX support.

Thanks @PunitLodha for the tip! Any idea / rough guess of when the HardsubX rewrite will be ready?

No rush or anything. Just a friendly ping asking about the ETA. :)

@utkarsh2102
Progress has been made on this. But the GSoC project was extended recently. So this will take a bit more time.
Do you build from the master branch, or will you have to wait for a new release?

Concerning Arch Linux, the AUR package is build from release versions.

Concerning Debian, the Debian package is built (and which is what we generally want to stick to) from a new release.

When trying to build ccextractor with ENABLE_FFMPEG it gives this error:

/ccextractor-build/CCExtractor/src/lib_ccx/ffmpeg_intgr.c:152:34: error: 'struct ffmpeg_ctx' has no member named 'codec_ctx'; did you mean 'dec_ctx'?

@prateekmedia it appears that these files weren't updated to ffmpeg 5. Was it intentional? Also would disabling ENABLE_FFMPEG limit any features in ccextractor? I want to use OCR and HardSubX.
