NvJPEGEncoder function EncodeFromBuffer or EncodeFromFd memory usage is too high

Hi,
I am using NvJPEGEncoder to Encode JPEG from YUV422 by GMSL2. I found that when I called the function EncodeFromBuffer() to encode yuv420 pictures to jpeg pictures, the usage of the memory increased 1.5GB. The size of the picture is 1920 * 1080 and the frame rate is 30. When I increased to 7 cameras, each of them occupied 1.5GB memory.
After that, I attemped another function EncodeFromFd, but memory usage of which is just the same. Does anyone know how to reduce the memory usage of the encoder, thanks a lot.

Hi,
There’s a known leak in JPEG encoding when using Jetpack 5.1.1. If you use the release or previous version, please upgrade to 5.1.2 and try.

Does the previous version also have this problem, such as 5.1.0?

Hi,

This is possible since the issue is fixed in Jetpack 5.1.2

Thank you very much, the problem has been solved after updating to 5.1.2.
