Hi,
I can still reproduce this bug in the DeepStream 7.0 Triton Docker image (nvcr.io/nvidia/deepstream:7.0-triton-multiarch) via
gst-launch-1.0 --gst-debug=jpegenc:5 -e filesrc location=./test.jpg ! nvjpegdec ! nvvideoconvert nvbuf-memory-type=3 ! 'video/x-raw,colorimetry=bt709' ! queue ! jpegenc ! filesink location=./dst_gray_235.jpg
GPU: GeForce RTX 3060 12 GB
DeepStream Version 7.0
TensorRT Version 8.6.1.6
NVIDIA GPU Driver Version 555.42.02
Could you please provide some advice on how to fix this?
