NvJpegDecoder issue with Arducam cameras

Elviron · January 2, 2025, 10:32am

Hello,

I have a Jetson Orin NX 16GB with Jetpack 6.0 on the board. I am working with Arducam B0249 camera and a MIPI CSI-2 to USB adapter as well as Arducam UB0213. Both cameras seem to have the same issue.

I have a code that is based on the jetson_multimedia_api samples and uses NvJpegDecoder to decode the MJPEG stream from my cameras. Previously I had exactly the same code on my Jetson Nano with Jetpack 4.6 and everything worked perfectly fine, then I adopted it to the new version of NvJpegDecoder on Jetson Orin NX and started having issues.

The thing is that when I run my camera at 1920x1080 resolution, I have only ~11FPS. I also get from your decoder logs that suggest kind of reinitializing the decoder at every frame (I may be wrong here). Here are the logs:

NvMMLiteOpen : Block : BlockType = 277
NvMMLiteBlockCreate : Block : BlockType = 277
NVMMLITE_NVVIDEODEC, <NvVideoBufferProcessing:6109> Consume the extra signalling for EOS
NvMMLiteOpen : Block : BlockType = 277
NvMMLiteBlockCreate : Block : BlockType = 277
NVMMLITE_NVVIDEODEC, <NvVideoBufferProcessing:6109> Consume the extra signalling for EOS
NvMMLiteOpen : Block : BlockType = 277
NvMMLiteBlockCreate : Block : BlockType = 277
NVMMLITE_NVVIDEODEC, <NvVideoBufferProcessing:6109> Consume the extra signalling for EOS
NvMMLiteOpen : Block : BlockType = 277
NvMMLiteBlockCreate : Block : BlockType = 277
NVMMLITE_NVVIDEODEC, <NvVideoBufferProcessing:6109> Consume the extra signalling for EOS
NvMMLiteOpen : Block : BlockType = 277
NvMMLiteBlockCreate : Block : BlockType = 277
NVMMLITE_NVVIDEODEC, <NvVideoBufferProcessing:6109> Consume the extra signalling for EOS
NvMMLiteOpen : Block : BlockType = 277
NvMMLiteBlockCreate : Block : BlockType = 277
NVMMLITE_NVVIDEODEC, <NvVideoBufferProcessing:6109> Consume the extra signalling for EOS
NvMMLiteOpen : Block : BlockType = 277
NvMMLiteBlockCreate : Block : BlockType = 277
NVMMLITE_NVVIDEODEC, <NvVideoBufferProcessing:6109> Consume the extra signalling for EOS
NvMMLiteOpen : Block : BlockType = 277
NvMMLiteBlockCreate : Block : BlockType = 277
NVMMLITE_NVVIDEODEC, <NvVideoBufferProcessing:6109> Consume the extra signalling for EOS
NvMMLiteOpen : Block : BlockType = 277
NvMMLiteBlockCreate : Block : BlockType = 277
NVMMLITE_NVVIDEODEC, <NvVideoBufferProcessing:6109> Consume the extra signalling for EOS
NvMMLiteOpen : Block : BlockType = 277
NvMMLiteBlockCreate : Block : BlockType = 277
NVMMLITE_NVVIDEODEC, <NvVideoBufferProcessing:6109> Consume the extra signalling for EOS

Still, the image is fine and I get no error. On Jetson Nano I had stable 30FPS with the same code.
I started my investigation and realized, that the issue is only at the 1080p. When I get lower or even higher resolution, everything works fine. At 2560x1440 I even got ~28FPS.
When I dumped my frame, I saw that it has proper JPEG headers at every resolution, so this is not the issue.

Of course, my first thought was that there is a bug in my code, so I compiled the 12_v4l2_camera_cuda sample and run my Arducam camera with it and there are those strange logs about extra EOS as well.

Please help. Jetson Nano cannot have better performance at MJPEG decoding than Orin NX…

Hi,
Are you able to upgrade to Jetpack 6.0GA 6.1 and give it a try? Certain issues are discovered and fixed in later Jetpack release.

Elviron · January 3, 2025, 7:45am

I think I already have Jetpack 6.0GA. This is what I get after typing sudo apt show nvidia-jetpack :

Or did you mean Jetpack 6.1?

DaneLLL · January 3, 2025, 8:04am

Hi,
You are right. It was a typo. Please try Jetpack 6.1.

Elviron · January 10, 2025, 7:18pm

Hi,
I have upgraded my Orin NX to Jetpack 6.1, but with no luck - the issue is still there.

DaneLLL · January 13, 2025, 3:09am

Hi,
Please try the sample:

/usr/src/jetson_multimedia_api/samples/12_v4l2_camera_cuda

We run it to launch AVerMedia CAM513 and Logitech BRIO 4K USB cameras. And don’t observe the issue. Please try and see whether the issue is still there.
