We’ve made some changes to the publicly released nvidia fork of the v4l2 plugins to add support for changing the quantization parameters for a specific region of interest. This can be found at v4l2: add support for nvidia-specific roi information · ystreet/gst-nvidia-v4l2@64d88ae · GitHub if you are interested. This change was made on top of L4T R32.6.1 tarball but should relatively easily apply to many other L4T versions.
Hi, Firstly thank you for providing your source code. I had combined into plugin and built it. But, It’s NOT operated as I expect. Is there any method of input option? So, I’d like to have a question about that. To adapt the ROI regions, I assume that gst_video_region_of_interest_meta_add_param() may be called prior to set operation (gst_video_region_of_interest_meta_get_param(). But I did NOT find in you source code for it. Please, give a guidance and comments for it. Thank you in advance.
