How to merge multiple GST batched buffer into one buffer

Please provide complete information as applicable to your setup.

Hi, Suppose I want to create a pipeline with 4 input streams, 2 streams to a people net and 2 to vehicle net.
After predicting using nvinfer module, I draw bounding boxes and thus have 2 batched GST buffers, how can I merge these two batched buffers into one and tilted then render them onto screen?
Thanks for your help.

Edit: I’ve read the deepstream muxer and it only supports RGBA/NV12 input buffers

No. Deepstream can not support such case now. You may consider to combine the two models together so that you can infer all streams with one batch.

Do you have another idea to tackle this problem. If I combine all streams together, it may slow down the inference process.

For current deepstream, no other suggestion.

What about using nvstreamdemux on both streams and nvstreammux again ?

It is not supported now. Recombining nvstreamdemux output with nvstreammux fails - Intelligent Video Analytics / DeepStream SDK - NVIDIA Developer Forums

Oh thanks alot, I’ve thought about implementing that but if it not working I try to find another way.
