I am using Deepstream 6.0 and trying to do some custom post processing inside a probe function on the sink of nvosd plugin. Is there a way to push back the post processed image back to the pipeline for visualization similar to the function that get the frame get_nvds_buf_surface¶
Thank you for your help

you can modify or add your display meta before nvosd pulgin, then nvosd will draw on frame, nveglglessink will display frame. please refer to deepstream sample deepstream-test1.
As far as I know, you cannot update frame in GstBuffer from a probe function. In the osd probe you’re actually making a copy of the original frame in GstBuffer.
You will need to implement your own plugin or can start from deepstream’s dsexample plugin.
There is no update from you for a period, assuming this is not an issue any more. Hence we are closing this topic. If need further support, please open a new one. Thanks
