how to add gstreamer1.0-plugins-nvv4l2camerasrc

[danny1209]

Hi all,

I put IMAGE_INSTALL_append += " gstreamer1.0-plugins-nvv4l2camerasrc " in local.conf and compiled.

want to use this command to stream to HDMI Display:
gst-launch-1.0 nvv4l2camerasrc sensor-mode=0 ! "video/x-raw(memory:NVMM), format=(string)GRAY8, width=(int)1792, height=(int)1204" ! fpsdisplaysink video-sink=fakesink text-overlay=false -e -v
but failed with this warning:
WARNING: erroneous pipeline: no property "sensor-mode" in element "nvv4l2camerasrc0"

could someone tell me how to install the gstreamer plugins properly? Thanks in advance.

The nvv4l2camerasrc doesn't have a sensor-mode property, nor does it support output formats other than UYVY. You can use the gst-inspect-1.0 command to see what different plugins are capable of. Perhaps it is the nvarguscamerasrc that you're actually wanting to use?

Hi @kekiefer ,

I do mean the plugin nvv4l2camerasrc, it´s working in Jetpack:

[danny1209]

in Jetpack:
the file is under: usr/lib/aarch64-linux-gnu/gstream-1.0/

it works fine. The color is green.

in Yocto:
the file is under: usr/lib/gstreamer-1.0

not green
and nor working

Well, then yes, I agree then it would be helpful to understand why there is a difference in these plugins, as meta-tegra builds nvv4l2camerasrc from the publicly available sources from NVIDIA, and that version doesn't contain a sensor-mode property, and only supports the UYVY format.

I don't know what the green means -- it's coming from bash colors, and doesn't on its own affect the way a library can behave. Maybe that green indicates it's a symlink to another plugin? Maybe it's just a permissions issue and not relevant at all?

The nvarguscamerasrc plugin does have a sensor-mode property.

I don't know what the green means

I think it means the executable bit is set? I don't think that would be relevant in this case.
