Tool/software:

Hi i'm using this pipeline

root@am62pxx-evm-lohr-recovery-mode:~# gst-launch-1.0 -v v4l2src device=/dev/video3 ! video/x-raw,format=UYVY,width=1280,height=720,framerate=30/1 ! videoconvert ! video/x-raw, width=1
280, height=720, framerate=30/1, format=NV12 ! waylandsink sync=false

but my CPU usage is too high.

How can I low the cpu usage?

Att.

    Hi Sergio,

    could you please replace software 'videoconvert' with hardware accelerated plugin 'tiovxcolorconvert' . 

    color conversion tasks to dedicated hardware accelerators on TI SoCs, leading to significantly lower CPU utilization and higher performance compared to software-based conversions.

    Hi, thank you for your quick response.

    when I run my pipeline with 'tiovxcolorconvert', I got this output 

    root@am62pxx-evm:~# gst-launch-1.0 -v \
    > v4l2src device=/dev/video3 ! video/x-raw,format=UYVY,width=1280,height=720,framerate=30/1 ! \
    > tiovxcolorconvert ! video/x-raw, width=1280, height=720, framerate=30/1, format=NV12 ! waylandsink sync=false
    WARNING: erroneous pipeline: no element "tiovxcolorconvert"

    root@am62pxx-evm:~# gst-inspect-1.0 tiovxcolorconvert
    No such element or plugin 'tiovxcolorconvert'

    How can I enable this tiovxcolorconvert?

    Best regards,

    Hi Sergio,

    tiovxcolorconvert is not present on  AM62P. 

    Can you share the output when you don't use videoconvert and use kmssink as the display sink instead of waylandsink. 

    I guess, waylandsink is doing an additional videoconvert before displaying the contents.

    Best Regards,

    Hi Suren

    here is the output 

    root@am62pxx-evm:~# gst-launch-1.0 -v v4l2src device=/dev/video3 ! video/x-raw,format=UYVY,width=1280,height=720,framerate=30/1 ! videoconvert ! video/x-raw, width=1280, height=720, framerate=30/1, format=NV12 ! kmssink

    What version of SDK are you testing with Sergio?

    kmssink driver-name=tidss sync=false 

    Also, I want you to remove the videoconvert from the pipeline, when using the above element (kmssink)

    Best Regards,

    Suren
