When I ran OpenGl applications in full screen mode, I could hit ESC or “Q” or “q” to quit.

I could not figure out how to quit “nvgstcapture” in full screen mode.

I tried to hit “q” everywhere on screen but could not quit “nvgstcapture”.

Does anyone know how to quit “nvgstcapture” in full screen mode?

Thanks in advance.

I’m using the latest Jetpack 2.3, i.e., L4T R24.2.1.
I tried both Nvidia and Leopard CSI-2 cameras, using:

gst-launch-1.0 nvcamerasrc fpsRange=“30.0 30.0” ! ‘video/x-raw(memory:NVMM), width=(int)1920, height=(int)1080, format=(string)I420, framerate=(fraction)30/1’ ! nvtee ! nvvidconv flip-method=2 ! ‘video/x-raw(memory:NVMM), format=(string)I420’ ! nvoverlaysink -e

hi yahoo2016,

for the gst-launch-1.0. you should use ctrl^c to shutdown the pipeline, it will send EOS signal since you had set “-e” option.
BTW, nvgstcapture-1.0 is support ‘q’ command to shutdown/terminate the streaming.
thanks

I believe I tried ctl-c, ctl-x and ctl-z for “gst-lauch”, I’ll try them again.

When I used “nvgtscapture-1.0” for Leopart IMX274 camera, I got only 640x480 display which is not full screen on 4K monitor.

“nvgtscapture-1.0 --help” showed 9 different resolutions, but when I tried “nvgtscapture-1.0 --video-res=x” (x=6,7,8, or 9), display stayed at 640x480 resolution.

I could not figure out how to change resolution and verify full screen mode using “nvgtscapture-1.0”. Leopart support suggested using “nvgtscapture-1.0 m 1 -video-res=x”, but it did not change video res.

Thanks

I figured out I should use “nvgtscapture-1.0 --prev-res=x” to set live display resolution.

“q” did work for “nvgtscapture-1.0”
