WIP: for early review only. Do not merge.

  • add cmake option to build with ffmpeg
  • search for ffmpeg at cmake time
  • include ffmpegs/libav headers in main.cpp
    Remaining todos:
  • if needed convert input file to wav 16khz in main.cpp

@ggerganov @slaren could you please early review before I move on ? Best, WT.

We can add the FindFFmpeg.cmake script in the cmake folder and use it to find ffmpeg libs

Probably the conversion functionality should be implemented in common.cpp so that it can be reused by all examples, not just main

Change the underscore in the filename to a dash for consistency: ffmpeg-transcode.cpp

Unfortunately cannot be built with FFmpeg 7.0.

can probably be fixed with:

#if LIBAVFORMAT_VERSION_MAJOR < 56
av_register_all(); // from avformat. Still a must-have call for ffmpeg v3! (can be skipped for later versions)
#endif

Change 56 to correct ffmpeg version. media-video/ffmpeg-4.4.4 seems to have 56 version (but i am not sure)
