Seems Michael Niedermayer wrote that manually, without AI. Good for him. :P

ffmpeg is great, I think nobody disputes this. I use it in two ways mostly:

1) one, via mpv, and 2) two, as conversion tool primarily

ffmpeg also has many really powerful filters, but these are very confusing to use IMO and not elegant at all. I'd wish we could use some kind of simple meta-language or so, in part similar to virtualdub/avisynth (not necessarily suggesting the same API or DSL here, but just the main idea to think of multimedia data as tangible to manipulation as if it were an object oriented system or datastream system; every time I have to use ffmpeg's filter system, I ask myself if nobody designs any of this ...).
