Gstreamer pluggin missing.

[bugtechz]

Hi,

I'm trying to run a video on a kv260.

I follow this tutorial (https://xilinx.github.io/kria-apps-docs/creating_applications/2022.1/build/html/docs/kria_vitis_acceleration_flow/petalinux-firmware.html) and I flash this petalinux (2022.1) with the configuration of the tutorial on the sd-card.

I saw that ffmpeg was not enabled so I follow the command below in this link (https://docs.amd.com/r/2022.1-English/ug1144-petalinux-tools-reference-guide/Adding-an-Existing-Recipe-into-the-Root-File-System) because I'm working with video -file.

After

-) petalinux -config -c rootfs where I enabled it

-) petalinux-build --sdk

-) ./sdk.sh

-) petalinux-package --wic --bootfiles "ramdisk.cpio.gz.u-boot boot.scr Image system.dtb"

Actually I run a c++ code created with Vitis 2022.2 where I print the build information with the function getBuildInformation() but I continue seeing this

Video I/O:

GStreamer: YES (1.18.5)

v4l/v4l2: YES (linux/videodev2.h)

gPhoto2: YES

without ffmpeg.

I also see this two warnings related to gstreamer that I don't understand how resolve.

[ WARN:0] global /usr/src/debug/opencv/4.5.2-r0/git/modules/videoio/src/cap_gstreamer.cpp (854) open OpenCV | GStreamer warning: Error opening bin: unexpected reference "video" - ignoring

[ WARN:0] global /usr/src/debug/opencv/4.5.2-r0/git/modules/videoio/src/cap_gstreamer.cpp (597) isPipelinePlaying OpenCV | GStreamer warning: GStreamer: pipeline have not been created

Unable to open file!

Could someone tell me what I'm doing wrong please?

Thanks in advance !
