Share yuv data between different processes

Hi,
The decoded YUVs are in NvBuffer. If you would like to transfer NvBuffer to other process directly, we don’t have the implementation. There is a similar topic:

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

Hi li lin, Please try to pass fd via socket: [s]https://openforums.wordpress.com/2016/08/07/open-file-descriptor-passing-over-unix-domain-sockets/[/s] 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.

So you would need to create shared memory(CPU memory) and copy NvBuffer to the memory for sharing to other processes, this may consume certain CPU loading though.
