 Yes. Indeed, it writes linear for something THAT CANNOT be linear.
 Ridiculous. You cannot see it in ffplay, since it does not support linear,
 but mpv (that does support linear) is broken (since mpv uses ffmpeg and
 ffmpeg added support for reading linear and stuff in
 0539f15bbb86c5e81af56454c94e2eddefd34b7c)!! WTF.

 On the other hand looks like chroma sitting in mpv is wrong if you will
 look into the zero of testsrc (chroma_location=unspecified of course).
