Exporting information to frame data is a hack, =E2=80=9Cthis lo= oks pointy, we have a hammer, let's nail it=E2=80=9D. It only works if the data is very flat. It does not work for data that comes at the end of the stream. It still requires a way to get the data out in a parse-friendly syntax when the program running is not ffprobe. Having an API and user interface for filters to return structured data is one of the reasons I want this API in libavutil.
