Motion vectors as side data during encoding #4

Hi

Please confirm if md_buf array in https://github.com/rockchip-linux/mpp/blob/develop/test/mpi_enc_test.c will be filled with motion vector information after encoding a given frame (h.264 of course ).

Is this buffer exposed up above in mpph264enc gstreamer plugin? Is there any other way I could get this data in gstreamer (sink or shared memory transfer from driver etc.,)

Thnx

I decided to make its as meta data in gstreamer, you should leave a message there not here.

Fix buffer overflow scanning soc_name.
73b5f21 
The soc_name we read from device-tree is NUL-separated so we need to
replace intervening NUL chars, but we don't want to replace the last
one, or the next call to strstr() will overflow the buffer.
