GStreamer + OpenCL Issues in SDK 1.5.1

Hi, Spanner-san.

 

I was able to get the camera demo working by applying the fix suggested by FUKU55-san in another thread (--disable-opencl).

 

(x) # ./inference.py resnet50-imagenet-onnx usb:0 --show-stats 
(o) # ./inference.py resnet50-imagenet-onnx usb:0 --show-stats --disable-opencl

 

It seems that the integration between GStreamer and OpenCL is unstable in SDK 1.5.1.

Hi,

I'm experiencing the same issue as here
The movie demo works but the camera demo fails.

 

 


Hi, Spanner-san.

In my case, I downloaded and recompiled the model zoo(see my log  ↑).

Hi ​@Hiroyuki Kojima-san!

Thanks for sharing your findings. Your workaround with --disable-opencl is really interesting. A couple of Axelera guys are looking into this and have asked if you could help us with a bit more info:

  1. Could you try running the pipeline again with the -vv option? This will give us full GStreamer debug logs.

  2. If possible, could you also try running the same pipeline using a video file or a fakesrc input, to help rule out USB camera quirks?

  3. Lastly, could you share the output of clinfo? It’s possible OpenCL might not be available on the system, and this will help confirm.

Really appreciate your help as we dig into it!


Hi, Spanner-san.

 

I will send you the demo operation command confirmation log you requested.

This time, a warning message appeared, but the camera demo worked even without adding --disable-opencl. Why is that?
