[mmapi] how many input buffer is supported by function "NvBufferComposite"

I use R28.2.
I gave 9 input buffers, but I could only stitch 8 buffers.
The last buffer cannot be stitched into the output image.
the parameters were correct.

From the macro definition, I guess that up to 16 buffer can be supported

Please share test code so that we can build and run to reproduce the issue. Thanks.

Did you ever find an answer to this? I am having the same problem. It only works with 8 buffers.

I am using r32.3.1.

Would be nice if you guys could share the source for these routines. I have posted about another problem with NvBufferComposite with width and height problems.



The limitation on TX1/Nano is 8 buffers. Please check CHAPTER 15: VIDEO IMAGE COMPOSITOR(VIC) in techinical reference manual:

The compositor implements much of the DirectX Video Acceleration 2.0 Enhanced Video Processor specification, including deinterlacing,
scaling, color conversion, proc-amp, and compositing for up to 8 input surfaces.

Sorry I thought I was on the Nano section and my question relates to Nano.

Never mind I found the same limitation in the TRM for Nano.

Thanks for pointing me in the right direction.

TX1 and Jetson Nano are with same constraints.
