[mmapi] how to transfer video YUV data between two processes

hello everyone.

I want to transfer video YUV data between two processes without memcpy.
I found that process A sent dma_buf fd to the process B, but process B can not use the fd.
Is there any good advice?

Hi li lin, it is not supported. We will evaluate to add the new feature.

Hi li lin,
Please try to pass fd via socket:

UPDATE 01/03/2018 socket does not work. sorry for the bad comment. As of now it is not possible to transfer dmabuf between two processes.
