Is there some way of converting RGB vasuface to NV12 vasurface in vaapi?

[lugui2009]

I have looked through all the funcions of vaapi ,but it seems that there are no such convertion functions . And I don't want to convert through CPU .is there someone who can tell me how to do it through vaapi? Thank you very much.

You should use the va_vpp video processing API for CSC, please refer to the comments and example in va_vpp.h. As for RGB support, it depends on the driver you are using. RGB is not supported if you are using https://github.com/intel/intel-vaapi-driver, you should use RGBX instead.
