Dears,
in "i.MX 8M Plus Camera and Display Guide" document (IMX8MPCDUG), in "3.4 Arbitrary Resolution Control" there is picture 17 shows 2 output buffers.
How can I access both buffers (before and after DeWrap)?
Hi,
IMHO You cannot access both outputs at the same time (before and after DeWrap). You can do (before or after DeWrap). The doc says "If the Dewarp output is used"
If Dewarp is deactivated in device tree or set to bypass in corresponding JSON config file, you get ISP Scale Down output. If Dewarp is used, all Images are passed through Dewarp before you can access them.
Also, "output buffers" are only accessible via V4L2 API (e.g doing: gst-launch-1.0 v4l2src num-buffers=1 device=/dev/video0 ! video/x-raw,width=3840,height=2160 ! videoconvert ! pngenc ! multifilesink location=test.png)
Community, correct me if I am wrong I don't think you can access video output buffers outside of V4L2.
