Nvompositor can only use nvoverlaysink when using nvsreammux

Hi,
When I use nvstreammux and nvinfer for inference, the inference result is input to nvcompositor, and the output of nvcompositor can only be received by nvoverlaysink, and it cannot be received correctly using other methods [such as xvimagesink]
The correct method:

And using xvimagesink received nvcompositor output:
replace the ! nvoverlaysink use:
! ‘video/x-raw(memory:NVMM),format=RGBA’
! nvvidconv
! videoconvert
! xvimagesink

the error is that:
WARN basetransform gstbasetransform.c:1355:gst_base_transform_setcaps: transform could not transform video/x-raw(memory:NVMM), width=(int)1920, height=(int)1080, framerate=(fraction)30/1, format=(string)RGBA, batch-size=(int)1, num-surfaces-per-frame=(int)1 in anything we support

Does anyone know why?
thanks.

Hi,
The nvcompositor plugin does not work in DeepStream SDK. Please use nvmultistreamtiler plugin.
