the pix_fmt describes the decoder output and encoder input
demuxers may set it but do not have to (especially if theres nothing
in their headers that contains that information)

AV_PIX_FMT_NONE is the default if it has not been set

this is documented in the header defining the field (avcodec.h)

it is not once nor twice but times without number that the same ideas make
their appearance in the world. -- Aristotle
