um yes, v4l2 in/out devices (lavd) do use a common file now present in 
lavc (ie: v4l2_fmt.c).

see libavcodec/Makefile:

OBJS-$(CONFIG_V4L2)                    += v4l2_fmt.o
OBJS-$(CONFIG_V4L2_M2M)                += v4l2_m2m.o v4l2_buffers.o

also note that the common file doesn't depend on the new V4L2_M2M 
decoders/encoders being available (only on V4L2)
