# Camera Source: [https://docs.qualcomm.com/doc/80-70014-50/topic/camera.html](https://docs.qualcomm.com/doc/80-70014-50/topic/camera.html) The QIM SDK camera plugin, camsrc, acts a client to Qualcomm camera service. The camera use cases show the execution and display of 1080p YUV streams from a live source. For more information on the camera plugin, see [camera architecture](https://docs.qualcomm.com/doc/80-70014-50/topic/camera-arch.html). ## Prerequisites Ensure that you complete the preconditions mentioned in [Multimedia use cases](https://docs.qualcomm.com/doc/80-70014-50/topic/multimedia-use-cases.html). Run the following commands: mount -o remount,rw /Copy to clipboard export XDG_RUNTIME_DIR=/dev/socket/westonCopy to clipboard export WAYLAND_DISPLAY=wayland-1Copy to clipboard ## Single 1080p YUV stream from live source Run the following command to execute the pipeline: gst-launch-1.0 qtiqmmfsrc name=camsrc video_0::type=preview ! video/x-raw\(memory:GBM\),format=NV12,width=1920,height=1080,framerate=30/1,compression=ubwc ! waylandsink fullscreen=true async=true sync=false Copy to clipboard The content from camera stream should be seen on the display. To stop the use case, press CTRL + C. The pipeline shows a single 1080p stream taken from the camera and sent to display. ![](data:image/png;base64,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) ## Three 1080p YUV streams from live source Run the following command to execute the use case: gst-launch-1.0 -e qtiqmmfsrc name=camsrc video_0::type=preview ! video/x-raw\(memory:GBM\),format=NV12,width=1920,height=1080,framerate=30/1,compression=ubwc ! waylandsink x=0 y=0 width=500 height=400 async=true sync=false camsrc. ! video/x-raw\(memory:GBM\),format=NV12,width=1920,height=1080,framerate=30/1,compression=ubwc ! waylandsink x=510 y=0 width=500 height=400 async=true sync=false camsrc. ! video/x-raw\(memory:GBM\),format=NV12,width=1920,height=1080,framerate=30/1,compression=ubwc ! waylandsink x=0 y=410 width=500 height=400 async=true sync=falseCopy to clipboard The content from camera streams should be seen on the display.
