Please test current FFmpeg git head, remove hide_banner from your command line and provide the command line together with the complete, uncut console output.

The output option “r 30” is unneeded and to answer your question: The semantic of “gray” is not fixed in the multimedia domain (but that shouldn’t rule out a bug, see above).
