+Subject: [PATCH] Include libavcodec/avfft.h only when AUDIO_VISUALIZATION is
+ enabled
+
+libavcodec/avfft.h is needed only when the code of AUDIO_VISUALIZATION
+is enabled (and it is off by default). This helps to build with
+FFmpeg 8, which ships libavcodec 62 that drops all the FFT APIs (used
+only within AUDIO_VISUALIZATION).
