Hi Allen, Please follow the steps to complete the JPEG encoding function. 1 Run the command $ gst-launch-1.0 v4l2src device=/dev/video0 num-buffers=300 ! ‘video/x-raw,width=1920,height=1080,format=(string)UYVY’ ! nvvidconv ! ‘video/x-raw(memory:NVMM),format=(string)NV12’ ! nvoverlaysink With output format being set, it should work fine. 2 Try the pre-release sample attached. You should see preview by running $ ./camera\_v4l2\_cuda -d /dev/video0 -s 1920x1080 -f UYVY -n 30 3 Refer to 09\_camera\_jpeg\_capture and pass (Fd) to jpeg encoder. The flow is V4L2 camera → NvBuffer(fd) → jpeg encoder [tegra\_multimedia\_api\_sample\_pre\_release.tar.gz](https://forums.developer.nvidia.com/uploads/short-url/y5AdhjCXr50amBgCv4LwTK1P438.gz) (15 KB) --- _[View the full topic](https://forums.developer.nvidia.com/t/how-to-convert-yuv-to-jpg-using-jpeg-encoder-hardware/47038)._
