Hello,
I am trying to add the v4l2loopback for using two /dev/video0 and /dev/video1 nodes for streaming.
Tried to do using below command and received the below message
Command:
gst-launch-1.0 v4l2src device=/dev/video0 ! tee name=tp ! queue ! v4l2sink device=/dev/video1
Error:
Setting pipeline to PAUSED ...
ERROR: Pipeline doesn't want to pause.
ERROR: from element /GstPipeline:pipeline0/GstV4l2Sink:v4l2sink0: Could not open device '/dev/video1' for reading and writing.
Additional debug info:
../../../git/sys/v4l2/v4l2_calls.c(668): gst_v4l2_open (): /GstPipeline:pipeline0/GstV4l2Sink:v4l2sink0:
system error: No such device or address
Setting pipeline to NULL ...
Freeing pipeline ...
Also tried using below command but getting the below error
Command:
modprobe v4l2loopback video_nr=1
Error:
modprobe: FATAL: Module v4l2loopback not found in directory /lib/modules/4.14.78-imx_4.14.78_1.0.0_ga+g94da7bd
How to solve this
