Hi, I’m trying the below pipeline as follows: gst-launch-1.0 -e videotestsrc pattern=black ! video/x-raw,width=320,height=240 ! nvvidconv ! queue ! tee name=t5 ! queue ! comp1.sink_0 v4l2src device=/dev/presentation ! queue ! tee name=t1 ! video/x-raw, width=1920, height=1080, framerate=60/1 ! vid…

Not sure I correctly understand your case (some unused queues), but trying to mimic it, this works: gst-launch-1.0 -e \ videotestsrc pattern=black ! video/x-raw,width=320,height=240,framerate=30/1 ! nvvidconv ! 'video/x-raw(memory:NVMM),format=NV12,width=1920,height=1080,pixel-aspect-ratio=1/1' ! t…

Hi, For further check, please try If it works with 4 videotestsrc sources If 4 videotestsrc sources work, please replace it with your sources one by one to clarify which one triggers the issue The issue may be from gdkpixbufoverlay location=logo-.png ! videoconvert ! imagefreeze ! queue ! comp…

I tried the way you mentioned earlier and now when i try to run the pipeline, i get a fully blacked-out preview . The used pipeline as follows: gst-launch-1.0 -e videotestsrc pattern=black ! video/x-raw,width=320,height=240 ! nvvidconv ! queue ! tee name=t5 ! queue ! comp1.sink_0 v4l2src devic…

Hi, The later command looks identical to the original one. Does it work with 4 videotestsrc? Have you identified which source triggers the issue?

Yes, the 4th video feed works , the problem occurs when i try to insert a picture. The used pipeline as follows: gst-launch-1.0 -e videotestsrc pattern=black ! video/x-raw,width=320,height=240 ! nvvidconv ! queue ! tee name=t5 ! queue ! comp1.sink_0 v4l2src device=/dev/presentation ! queue ! te…

Hi, Single image is no supported in nvcompositor. Please refer to the command to make it as a continuous frame source: $ gst-launch-1.0 multifilesrc location=src%03d.png loop=1 ! pngdec ! videoparse format=2 framerate=30/1 ! nvvidconv ! 'video/x-raw(memory:NVMM)' ! nvoverlaysink

Thank You. This was the needed output.

Hi, The below Pipeline works fine. But the problem is the png images does not appear transparent. It has a black background. gst-launch-1.0 -e videotestsrc pattern=black ! video/x-raw,width=320,height=240 ! nvvidconv ! queue ! tee name=t5 ! queue ! comp1.sink_0 v4l2src device=/dev/presentation ! q…

Hi,
Transparent blending is not supported in nvcompositor plugin. Please note this.
