Not related to this forum But someone might know the solution




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

I follow this tutorial ( 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 ( because I'm working with video -file.



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

-) petalinux-build --sdk

-) ./

-) 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 !

Hi Bugtechnz,


Your GStreamer issue is because the data stream is not present in a GSTPipeline. To use GStreamer, OpenCV expects a valid pipeline. You may check the Gstreamer capabilities.


However, for better support regarding OpenCV. I suggest you post your question on OpenCV Github. There is a similar issue in the forum that might help you.


Therefore, since this is not related to OpenVINO. I will proceed to close the case. This thread will no longer be monitored since we have provided information. If you need any additional information from Intel, please submit a new question.
