Hi,
I am trying to demux multiple streams after dsexample with the blur option. It turns out nvdemux is not working with RGBA. How do I adjust the pileline below to make demux work?

• How to reproduce the issue ? (This is for bugs. Including which sample app is using, the configuration files content, the command line used and other details for reproducing)

Minimum example (the RGBA conversion breaks the pipeline, without it works):

gst-launch-1.0 filesrc location = ./streams/sample_1080p_h264.mp4 ! decodebin ! m.sink_0
filesrc location = ./streams/sample_1080p_h264.mp4 ! decodebin ! m.sink_1
nvstreammux name=m width=1920 height=1080 batch-size=4 batched-push-timeout=40000 !
queue ! nvinfer config-file-path=./configs/deepstream-app/config_infer_primary.txt batch-size=4 !
nvvideoconvert nvbuf-memory-type= nvbuf-mem-cuda-unified !
‘video/x-raw(memory:NVMM), format=RGBA’ !
nvstreamdemux name=d
d.src_0 ! queue ! nvvideoconvert ! nvdsosd ! nveglglessink
d.src_1 ! queue ! nvvideoconvert ! nvdsosd ! nveglglessink \

Full example, to show why I need the RGBA conversion:
gst-launch-1.0 filesrc location = ./streams/sample_1080p_h264.mp4 ! decodebin ! m.sink_0
filesrc location = ./streams/sample_1080p_h264.mp4 ! decodebin ! m.sink_1
nvstreammux name=m width=1920 height=1080 batch-size=4 batched-push-timeout=40000 !
queue ! nvinfer config-file-path=./configs/deepstream-app/config_infer_primary.txt batch-size=4 !
nvvideoconvert nvbuf-memory-type= nvbuf-mem-cuda-unified !
‘video/x-raw(memory:NVMM), format=RGBA’ !
dsexample full-frame=0 blur-objects=1 !
nvstreamdemux name=d
d.src_0 ! queue ! nvvideoconvert ! nvdsosd ! nveglglessink
d.src_1 ! queue ! nvvideoconvert ! nvdsosd ! nveglglessink \
