The driver will just use C > gstreamer may (or may not) use SIMD. LOL fail post, to clarify, the driver will not convert BGRx to anything (would be a nice feature if the GPU could do it). If you tell gstreamer to convert BGRx to I420 then the driver will just change it to nv12 using CPU C code, so you may as well tell gstreamer to convert to NV12 in the first place.
