Nvcompositor gstreamer warnings

alanser · June 19, 2024, 7:27pm

I use nvcompositor to display a 4:3 source correctly which it does flawlessly. My application sets the gstreamer GST_DEBUG=2 to log gstreamer issues. When I do this nvcompositor emits a log message every frame time with useless (to me) log info:
Pipeline is PREROLLING …
0:00:00.130743040 4420 0xaaaae59d5aa0 ERROR default video-frame.c:181:gst_video_frame_map_id: invalid buffer size 64 < 115200
0:00:00.130867936 4420 0xaaaae59d5aa0 WARN videoaggregator gstvideoaggregator.c:430:gst_video_aggregator_convert_pad_prepare_frame: Could not map input buffer

How do I resolve this?

To recreate:
root@xavier:~# GST_DEBUG=2 gst-launch-1.0 videotestsrc ! nvvidconv ! nvcompositor ! fakesink -e

I’ve got the exact same issue. As soon as I introduce the nvcompositor I start getting the “invalid buffer size” and “Could not map input buffer”.

Hi,
Certain parameters/properties have to be configured to nvcompositor plugin. Please refer to the commands in gstreamer user guide and give it a try:

I tried the pipeline as in Accelerated GStreamer — NVIDIA Jetson Linux Developer Guide 1 documentation with a minor mod to use nvdrmvideosink instead of nv3dsink and the issue persists:

Hi,
Please clearly configure format in source pad and sink pad of nvcompositor plugin. It looks the format is not correctly set and triggers the issue. It should be working well if the caps are well configured.

And the nvcompositor plugin is open source. For investigating further, you may add prints to the source code and check.
