We are using li-jetson-kit-imx274cs camera kit https://shop.leopardimaging.com/product.sc?productId=288 with L4T R28.1 and have installed the corresponding driver. Everything is working fine with nvcamerasrc, but not with v4l2src which we would prefer to use due to less converting between formats and therefore less latency.
We have tried the following pipe from “Accelerated GStreamer User Guide” :
gst-launch-1.0 v4l2src device="/dev/video0" ! "video/x-raw, width=640, height=480, format(string)I420" ! xvimagesink -e
, but gets the following error message:
ERROR: from element /GstPipeline:pipeline0/GstV4l2Src:v4l2src0: Internal data flow error.
Additional debug info:
gstbasesrc.c(2948): gst_base_src_loop (): /GstPipeline:pipeline0/GstV4l2Src:v4l2src0:
streaming task paused, reason not-negotiated (-4)
EOS on shutdown enabled – waiting for EOS after Error
Waiting for EOS…
Got EOS from element “pipeline0”.
EOS received - stopping pipeline…
In addition we want to use appsink as well. Therefore we were wondering if someone have any working pipes with the v4l2src?
