Ported FFmpeg API usage from 4.x to 6.x

[dkozel]

I wanted to use AEO Light on Ubuntu 24.04 and found that it depended on a much older version of FFmpeg libraries. I have updated the code to use FFmpeg 6.x APIs and successfully extracted stereo audio from a folder of DPX frames of 1950's 35mm film. I'll do some more testing on other formats, but wanted to publish these changes to see if you would be interested in integrating them.

I have some limited ability to test on Windows, but would prefer to work with someone on reviewing that.

I haven't added documentation or a README, though I think the project would strongly benefit from both. I can provide updated instructions for building on Linux, including an updated Dockerfile.

Thank you for making and sharing this tool.

I also have a fork where I have updated libraries, but the maintainers have not been responding. If you want to chat some time let me know. I've discovered there are issues with modern Apple devices that make the application unusable which is a main problem I've had when compiling my updated version as well.

Derek, thank you for addressing the legacy FFmpeg calls. I rebuilt my development machine this past month but still have not gotten QC Creator up and running on it. Will try to do this over the holidays, but even then I’ll be able to test on Mac OS 26. A colleague who maintains a Windows CQ dev environment may be able to take a look in the next month as well. — greg

@kylemikableh I took a look at your branch but didn't want to build on top of the CMake changes (which I love!) given that the upstream had ported to Qt6 earlier this year and I wanted to be able to open this PR. Did you have updates other than to Qt? I found a DPX library version which has some fixes and features. https://github.com/manuvi/dpx

@wilsbacher That's great, please keep me in the loop. I'm just using this for a single video file, it was mostly an evening's fun. Happy to do whatever's needed to get this contribution merged. It would be great to visit the topic of documentation. I'll open an issue or PR with some content there, if you and your colleague can contribute instructions for building on Mac and Windows that'd be helpful to others.

Hi There! It was working fine a few months ago and now it crashes all the time. What can I do to fix my problem? I re-downloaded and re-installed it and the same problem keeps happening. I'm assuming it's caused by Microsoft updating crap on my PC when I don't want it to. Here's what's running: Edition Windows 10 Pro Version 22H2 Installed on &lrm;10/&lrm;7/&lrm;2020 OS Build 19045.6466 Thank you in advance, Russell RUSSELL CALABRESE ARTWERKS ***@***.*** ***@***.***) Phone: 413-667-0237 Text: 818-267-4344
