FFmpeg 6.0 won't work because the header files can't connect or interact with each other. How do I fix the files ?
11 septembre 2023, par Señor TontoI am creating a win32 API C++ application with Microsoft Visual Studio 2022 in a .sln file. I've got quite far in basic functionalities & decided to try out video decoding & playing ; I've practiced this before but not with C++. So, I looked to see good libraries & found FFmpeg. Of course, I thought this would be quite straightforward - just import the headers & code, right ? No. Firstly, the FFmpeg I'm using is one of the pre-built binaries. The 'ffmpeg-master-latest-win64-gpl-shared.zip' From the BtbN Github repository. I decompressed it with WinRar & placed the files in Program Files (x86). Later on, I realised my mistake of placing it with 32-bit programs since it's a 64-bit build. So I transferred it to Program Files. Even after this though my issue persists. The issue being that the .h files of FFmpeg cannot communicate with each other. For some reason, they can't navigate to where the header files are. I am quite sure the reason for this may have something to do with where I save the files, the directory. Nowhere on the FFmpeg website can I see where you're expected to have the file directory at. I am sure there's a preset file path that is expected. Maybe I've named the FFmpeg folder incorrectly ? Or maybe it's not meant to go in Program Files ? The current directory for the FFmpeg folder for me is : C :\Program Files\FFmpeg. Below I will provide pictures of the errors I get where the code can't connect to other .h files as well as the file path. I'll also provide my code.

I severely doubt my code has anything to do with the issue though. It's probably directory-based. I just placed wWinmain here to keep with the character limit.

As seen in this output, the 1st frame appears to be a P frame. I'm curious as to how will the decoder decode this frame without a preceding I frame (key frame) ? The P frame will not have enough information to reconstruct the image from its residual data without the key frame.

Process hangs and I see that ffmpeg uses 500% of the CPU. Any idea how to fix (deal with) this ?


I can open both videos on my computer and play them.
