Hello, I’m attempting to create a plugin that will save each frame that the object got detected. I attempted to save frames by modifying the sample plugin code provided by Nvidia gstdsexample_optimized. Using NvBufSurfaceMap, I map the buffer to be accessible by the CPU. This buffer is converted to cv::Mat and cloned so that I may process and save these photos in a separate thread immediately after pushing the buffer to a downstream element. The issue is that this method (matrix cloning) takes a long time and degrades performance. To save time, I tried to create empty matrixes while initializing the plugin and pulling and pushing it to the queue while copying and writing the picture in distinct threads, but it didn’t help much.
I was wondering if there were any other options for dealing with this issue.
