gst-launch-1.0 can not capture camera forever ?

Hi !

I’m trying to use the following command to capture the camera forever

gst-launch-1.0 nvcamerasrc sensor-id=0 num-buffers=300 fpsRange="60.0 60.0" ! 'video/x-raw(memory:NVMM), width=(int)3840, height=(int)2160, format=(string)I420, framerate=(fraction)60/1' ! nvvidconv ! 'video/x-raw(memory:NVMM), format=(string)NV12' ! omxh264enc ! qtmux ! filesink location=/tmp/test.h264

But the program always terminates after about 5 seconds (num-buffers = 300) like this

Available Sensor modes : 
3840 x 2160 FR=60.000000 CF=0x1009208a10 SensorModeType=4 CSIPixelBitDepth=10 DynPixelBitDepth=10
1920 x 1080 FR=60.000000 CF=0x1009208a10 SensorModeType=4 CSIPixelBitDepth=10 DynPixelBitDepth=10
1280 x 720 FR=60.000000 CF=0x1009208a10 SensorModeType=4 CSIPixelBitDepth=10 DynPixelBitDepth=10

But I’d like to let it run forever, is this possible ? Thanks in advance !

Hi,
You have to remove ‘num-buffers=300’ from the pipeline, or it stops when capture frames reach 300.

Hi ! Thanks for this ! It works now !
