Even if our code compiles it does not work anymore ...

=========
There is no video filtering example in doc/examples.
How I supposed to know what should be put there now?
I have read a discussion on reddit that -pix_fmt possibly is deprecated(?) in favour of -vf format= or -pixel_format https://www.reddit.com/r/ffmpeg/comments/1du0mia/vf_formatpixel_format_vs_pi...
