Question about the operation when using imxvideoconvert_g2d with gstreamer.

kuri — Tue, 08 Aug 2023 01:11:40 GMT

I am conducting tests with the following commands in gstreamer.
However, when attempting to output from imxvideoconvert_g2d to appsink, the operation comes to a halt.
What could be the potential causes of this issue?

gst-launch-1.0 v4l2src device=/dev/video1 ! imxvideoconvert_g2d ! autovideosink
OK: Functions correctly.

gst-launch-1.0 v4l2src device=/dev/video1 ! videoconvert ! appsink name=sink
OK: Functions correctly.

gst-launch-1.0 v4l2src device=/dev/video1 ! imxvideoconvert_g2d ! appsink name=sink
NG: The operation comes to a halt.
