That's correct, mpdecimate currently only supports (taken from the
source code):

AV_PIX_FMT_YUV444P
AV_PIX_FMT_YUV422P,
AV_PIX_FMT_YUV420P,
AV_PIX_FMT_YUV411P,
AV_PIX_FMT_YUV410P,
AV_PIX_FMT_YUV440P,
AV_PIX_FMT_YUVJ444P,
AV_PIX_FMT_YUVJ422P,
AV_PIX_FMT_YUVJ420P
AV_PIX_FMT_YUVJ440P,
AV_PIX_FMT_YUVA420P,
AV_PIX_FMT_GBRP,
AV_PIX_FMT_YUVA444P,
AV_PIX_FMT_YUVA422P
