# Camera Source: [https://docs.qualcomm.com/doc/80-70020-50/topic/camera.html](https://docs.qualcomm.com/doc/80-70020-50/topic/camera.html) The Qualcomm IM SDK camera plugin, camsrc, acts as a client to the Qualcomm camera service. The camera use cases show the execution and display of the 1080p YUV streams from a live source. For more information about the camera plugin, see [camera architecture](https://docs.qualcomm.com/doc/80-70020-50/topic/architecture.html#camera). ### Prerequisites - Complete the preconditions mentioned in [Run multimedia use cases](https://docs.qualcomm.com/doc/80-70020-50/topic/multimedia-use-cases.html). - In the terminal of the target device, run the following command to configure the display: mount -o remount,rw /Copy to clipboard export XDG_RUNTIME_DIR=/dev/socket/weston && export WAYLAND_DISPLAY=wayland-1Copy to clipboard ### Single 1080p YUV stream from live source Run the use case on the target device: gst-launch-1.0 -e qtiqmmfsrc name=camsrc video_1::type=preview ! video/x-raw,format=NV12,width=1920,height=1080,framerate=30/1,interlace-mode=progressive,colorimetry=bt601 ! waylandsink fullscreen=true sync=falseCopy to clipboard The content from the camera stream is displayed. To stop the use case, use CTRL + C. The following pipeline shows a single 1080p stream taken from the camera and sent to display. ### Three 720 YUV streams from live source Run the use case on the target device: gst-launch-1.0 -e qtivcomposer name=mixer sink_0::position="<0, 0>" sink_0::dimensions="<480, 270>" sink_1::position="<480, 0>" sink_1::dimensions="<480, 270>" sink_2::position="<960, 0>" sink_2::dimensions="<480, 270>" mixer. ! queue ! waylandsink fullscreen=true qtiqmmfsrc name=camsrc camera=0 video_0::type=preview video_1::type=video ! video/x-raw,format=NV12_Q08C,width=1280,height=720,framerate=30/1,interlace-mode=progressive,colorimetry=bt601 ! queue ! mixer. camsrc. ! video/x-raw,format=NV12,width=1280,height=720,framerate=30/1,interlace-mode=progressive,colorimetry=bt601 ! queue ! mixer. camsrc. ! video/x-raw,format=NV12,width=1280,height=720,framerate=30/1,interlace-mode=progressive,colorimetry=bt601 ! queue ! mixer.Copy to clipboard The content from camera streams is displayed. To stop the use case, use CTRL + C. Note: With the GMSL camera, it's been observed that the display doesn't work and the use case doesn't stop when using CTRL + C. The following pipeline shows three 720p streams taken from the camera and sent to display with each stream displayed at different positions on the screen. ### Request many streams with different fps from camera Run the following use cases on the target device: - Two streams with capture request mode at 30 fps/15 fps: gst-launch-1.0 -e --gst-debug=fpsdisplaysink:6 qtiqmmfsrc name=qmmf frc-mode=capture-request video_0::type=video video_1::type=preview ! video/x-raw,format=NV12,width=1920,height=1080,framerate=30/1 ! fpsdisplaysink name=disp1 signal-fps-measurements=true text-overlay=false video-sink="fakesink" qmmf. ! video/x-raw,format=NV12,width=1920,height=1080,framerate=15/1 ! fpsdisplaysink name=disp2 signal-fps-measurements=true text-overlay=false video-sink="fakesink"Copy to clipboard - Two streams with capture request mode at 17 fps/10 fps: gst-launch-1.0 -e --gst-debug=fpsdisplaysink:6 qtiqmmfsrc name=qmmf frc-mode=capture-request video_0::type=video video_1::type=preview qmmf.video_0 ! video/x-raw,format=NV12,width=1920,height=1080,framerate=17/1 ! fpsdisplaysink name=disp1 signal-fps-measurements=true text-overlay=false video-sink="fakesink" qmmf.video_1 ! video/x-raw,format=NV12,width=1920,height=1080,framerate=10/1 ! fpsdisplaysink name=disp2 signal-fps-measurements=true text-overlay=false video-sink="fakesink"Copy to clipboard - Two streams with capture request mode at 5 fps/25 fps: The smaller frame rate is processed first and the camera updates the frame rate on the second stream. gst-launch-1.0 -e --gst-debug=fpsdisplaysink:6 qtiqmmfsrc name=qmmf frc-mode=capture-request video_0::type=video video_1::type=preview qmmf.video_0 ! video/x-raw,format=NV12,width=1920,height=1080,framerate=5/1 ! fpsdisplaysink name=disp1 signal-fps-measurements=true text-overlay=false video-sink="fakesink" qmmf.video_1 ! video/x-raw,format=NV12,width=1920,height=1080,framerate=25/1 ! fpsdisplaysink name=disp2 signal-fps-measurements=true text-overlay=false video-sink="fakesink"Copy to clipboard ### Set sensor mode Set the sensor mode in the camsrc plugin: export GST_PLUGIN_PATH=/usr/lib/gstreamer-1.0 && gst-launch-1.0 qtiqmmfsrc camera=0 name=camsrc sensor-mode=0 ! video/x-raw,format=NV12,width=1920,height=1080,framerate=30/1 ! multifilesink enable-last-sample=false location="/opt/frame%d.yuv" max-files=5Copy to clipboard For `sensor-mode=
