# Image segmentation and encode with Neural Processing SDK Source: [https://docs.qualcomm.com/doc/80-70015-50/topic/single-camera-stream-with-image-segmentation-and-encode-with-deeplabv3-quantized.html](https://docs.qualcomm.com/doc/80-70015-50/topic/single-camera-stream-with-image-segmentation-and-encode-with-deeplabv3-quantized.html) The use case uses the DeepLab v3 model with the Qualcomm Neural Processing SDK runtime to compose the semantic segmentations and original video stream, encode this stream, and then multiplex it in an MP4 container. Run the use case: gst-launch-1.0 -e --gst-debug=2 \ qtiqmmfsrc name=camsrc ! video/x-raw\(memory:GBM\),format=NV12,width=1920,height=1080,framerate=30/1,compression=ubwc ! queue ! tee name=split \ split. ! queue ! qtivcomposer name=mixer sink_1::dimensions="<1920,1080>" sink_1::alpha=0.5 ! queue ! video/x-raw\(memory:GBM\),format=NV12,width=1920,height=1080,interlace-mode=progressive,colorimetry=bt601 ! v4l2h264enc capture-io-mode=5 output-io-mode=5 ! h264parse ! queue ! mp4mux ! queue ! filesink location=/opt/video.mp4 \ split. ! queue ! qtimlvconverter ! queue ! qtimlsnpe delegate=dsp model=/opt/deeplabv3_resnet50.dlc ! queue ! qtimlvsegmentation module=deeplab-argmax labels=/opt/deeplabv3_resnet50.labels ! video/x-raw,width=640,height=360 ! queue ! mixer.Copy to clipboard To stop the use case, press CTRL + C. Figure : Pipeline for image segmentation and encode with qtivcomposer  The figure shows the flow of the use case execution: 1. Identify scenes from a video stream coming through a camera source. 2. Compose semantic segmentation and video stream using qtivcomposer. 3. Encode the stream as an H.264 bit stream and multiplex the stream in an MP4 container. The table provides the sequential processing stages of the pipeline execution: | Process | Description | | --- | --- | | [qtiqmmfsrc](https://docs.qualcomm.com/doc/80-70015-50/topic/qtiqmmfsrc.html) |
The segmentation model uses this tensor stream for
inferencing.
In this use case, qtimlvsegmentation does the
following:
