There is a message within the FFmpeg output but the way it is worded sounds like the option is only needed for greater compatibility and not for the command to work, and it does not make clear why the user should have to worry about pixel formats especially if the profile only supports 4:2:0. There is no indication in the documentation that this is necessary or what pixel format should be specified for H.264 baseline, main, or high profile.

It makes the user specify the pixel format even when only 4:2:0 will work. Even when a profile is specified explicitly, FFmpeg will choose a pixel format that is not compatible with the profile that is specified. Right now that works for some things like cabac but is broken for pixel format. It is expected that the other codec parameters can be chosen automatically based on the profile. The H.264 profile that is supported by a player or device is usually specified in the documentation or technical specifications, and its purpose is to make knowledge of the other technical codec parameters unnecessary for most users. Users are more likely to know what they need in terms of H.264 profiles, rather than lower level details like pixel formats, cabac, 8x8 transforms, etc.
