Hello to all,

Thank you in advance for quite answer,
Gaylord

PS: examle pipeline: gst-launch-1.0 imxv4l2src device=/dev/video0 ! video/x-raw, width=1920, height=1080 ! overlaysink

Hi Gaylord

one can try kernel boot parameter dmfc=3  and with lower

resolutions to check if this is caused by performance issues.

Recheck gstreamer usage with sect.7.5 Overlaysink usage atatched

Linux Manual.

Best regards
igor
