You could use a filter: https://ffmpeg.org/ffmpeg-filters.html
Hi, I don't want to use ffmpeg cmd method to archive this, In my situation , I must frame by frame to done this, (there is a lot of code already writen), I want to use ffmpegframegrabber / recoder /frame's direction, And do some sample data operate to archive this, can you give me some help about this direction? or use FFmpegFrameFilter? Is there some example about my audio mix purpose?
Again, there are a couple of examples of FFmpegFrameFilter in the samples, but we can use any other filter command: https://github.com/bytedeco/javacv/tree/master/samples
ok I'll try it, thank you
