    Hello,

    Please provide more information regarding the resolution, format, etc what your video source provides.
    Is this custom board or it is EVM?
    Did you verify that the patch from this is applied:
    e2e.ti.com/.../2023362
    Do you observe the same problem with the latest PSDK?
    Please try yavta and let me know the result(check the wiki page below)

    Hello,

    Could you run this command:
    gst-launch-1.0 v4l2src device=/dev/video1 num-buffers=1000 io-mode=4 ! 'video/x-raw, format=(string)YUY2, width=(int)1280, height=(int)720' ! queue ! vpe num-input-buffers=8 ! queue ! fakesink --gst-debug=2
    and post the output.

    BR

    Hello,

    Could you try to increase cma in bootargs.
    You could set cma=64MiB in uEnv.txt file and verify when the board is booting this value is accepted.
    You could also check this chapter of the user guide:
    processors.wiki.ti.com/.../Linux_Core_VIP_User's_Guide
    and share the log files.
