ffpyplayer build fails with ffmpeg 8.0.1 (from develop)

I am building `ffpyplayer` (version: v4.5.1) and I see that the `ffmpeg` version got upgraded to `8.0.1` and it throws below error.

Error:
```bash
/home/somnath/codes/git/my-org/image-to-animation-offline/kivy/.buildozer/android/platform/build-arm64-v8a/build/other_builds/ffpyplayer-openssl/arm64-v8a__ndk_target_28/ffpyplayer/ffpyplayer/pic.c:773:10: fatal error: 'libavcodec/avfft.h' file not found

```

Start with ffpyplayer/pic.c and the reported ffmpeg 8.0.1 build output, then inspect how ffpyplayer is built in the Android packaging path. Reproduce the failure with ffmpeg 8.0.1 and determine the project change needed for the build to complete without the missing avfft.h error.
