Failed to create buffer in pylonsrc

[rbnrtg]

Hi,

I am running the following pipeline on my ARM board and sending the stream to an RTSP server:

gst-launch-1.0 pylonsrc ! video/x-raw, width=1920, height=1080,format=GRAY8 ,framerate=30/1 ! videoconvert ! queue ! x264enc bitrate=26000 speed-preset=ultrafast tune=0 ! video/x-h264,profile=main ! rtspclientsink protocols=tcp location=rtsp://127.0.0.1:8554/video

But when the pipeline runs for a while, showing the GStreamer logs, I see the following error displayed:

My camera is Basler daA3840-45uc (USB Model).

What could be the reason for this error given by the pylonsrc source?
