NVMM Memory Pipeline Encoders Broken When Coexisting with bufapi=true DeepStream Pipeline

[Fiona.Chen]

As you said

@mgerov

In the appsink we are Modifying the buffer using VPI and pushing it (As a Surface) to the Detector.

Please tell us what kind of surface do you use.

In the following pipeline, you use nvvideoconvert in the pipeline, so it is a DeepStream pipeline

@mgerov

appsrc ! video/x-raw(memory:NVMM), format=RGBA, width=(int)X, height=(int)Y, framerate=1/1 ! nvvideoconvert output-buffers=8 compute-hw=0 nvbuf-memory-type=4 ! “video/x-raw(memory:NVMM), format=NV12, width=(int)X height=(int)Y” ! MUX.sink_0 nvstreammux name=MUX batch-size=1 width=X height=Y batched-push-timeout=4000 compute-hw=2 nvbuf-memory-type=4 ! nvinfer name=INFER config-file-path=“pgie_config.txt” ! fakesink sync=false

But with the sender(appsink) pipeline, you disable DeepStream flag with nvjpegdec, so it is a Jetson GStreamer pipeline. The two types pipelines can’t work together.
