thank you for your help!

in my opinion, i want to make the filter can automatic judge whether using
the OPENCL share buffer. i just want to know if i can use the data[5] of
the avframe as the pointer which can restore the OPENCL share buffer. if
the community confirm it, i will implement a patch with my design.
