Hello,
I am trying to use the fallbackswitch plugin with nvarguscamerasrc on a
dual camera video recording pipelin.
The goal is to keep the pipeline working when one camera is disconnected
(LI-IMX390 camera on NVidia Jetson NX)
I run the following pipeline :
gst-launch-1.0 -v \
nvarguscamerasrc sensor-id=0 name=video_element_0 !
'video/x-raw(memory:NVMM),width=1920,height=1080,format=NV12,framerate=30/1'
! fallbackswitch name=s ! queue ! nvv4l2h265enc control-rate=0 profile=1
! h265parse ! queue ! mpegtsmux name=mux ! filesink location="test.ts"
name=filesink_element \
videotestsrc !
'video/x-raw,width=1920,height=1080,format=NV12,framerate=30/1' ! s.
But I get the following error message :
WARNING: erroneous pipeline: could not link videotestsrc0 to s, s can't
handle caps video/x-raw, width=(int)1920, height=(int)1080,
format=(string)NV12, framerate=(fraction)30/1
Any idea ?
