Error: gst-resource-error-quark: Failed to allocate a buffer

I use test1-sample to test camera, it will not crash in a long time, and I change the pipeline the same with the one in the test1-usb sample, it still crash,

could you narrow down this issue? you can dump the media pipeline by this method.

@zhang.ga

In your pipeline, the width and height of streammux are different with them in decoder, is this right?

streammux requires setting width and height. for performance, you can set it to the decoder’s output resolution, which can be got from the media pipeline.

@zhang.ga

I use decoder instead of videoconvert, and add nvvideoconver and vosd behind pgie, crash still happened.

the DeepStream original sample run well. you can check if the CPU/GPU utilization is high. please simplify the code to check which new code causes the crash.
