How to deploy the image enhancement algorithm with deepstream

How to deploy the image enhancement algorithm with deepstream? The output of nvinfer is the enhanced image. How to return to the pipeline? When I try to sink, I still save the original low brightness image

Question:I use deepstream to infer an image enhancement model. Its output is an enhanced image, which has been converted into an engine file. I want to realize the output (sink) of the enhanced video. However, I saved MP4 through sink and found that the result MP4 video was not enhanced. What’s the reason? thank you!!!

Yeah, I think you need to save the output from the engine. the output sink always saved the original stream.
Such as if your model is a detector, the model just output the tensor containing bbox, DS will not save the tensor from model, it just parse the tensor and attach the bbox to meta data, is that clear for you?

Yes, but I want to achieve an effect similar to replacing the original stream. What should I do?
