• Issue Type( questions, new requirements, bugs): requirements
• How to reproduce the issue ? (This is for bugs. Including which sample app is using, the configuration files content, the command line used and other details for reproducing)
**• Requirement details: we are using gst-nvdspreprocess plugin in my pipeline. The input to pipeline is 2K resolution video.

gst-nvdspreprocess plugin is using libnvds_custom_sequence_preprocess.so for custom tensor creation. gst-nvdspreprocess works on frame and resize to 224x224. My requirement is to discard original frame after resize before sending to downstream. Let me know how can we dump original frame?

The pipeline will not discard the original frame.

There are may ways to dump original frame. You can refer to our sample demo to learn how to save the frame.

Thanks for your reply.
Let me correct if you understood it correctly or not. I want to free the memory allocated to original frame after resizing in preprocess plugin. Will it possible to free the memory as original frame is not required.

This processing is handled through the buffer pool, so you don’t need to care about memory usage here.
