Captures the live stream from camera.
Uses tee to split the stream for inferencing.
Captures the video stream using filesrc, followed by qtdemux, which demultiplexes the stream.
Uses tee to split the stream for inferencing.
Captures the RTSP stream using rtspsrc, followed by rtph264depay for video extraction.
Uses tee to split the stream for inferencing.
Receives the video stream on its sink pad.
Performs the following preprocessing on the stream data. This preprocessing is done when the model expects floating-point values as input.
Color conversion
Scaling (up or down)
Normalization
Converts the preprocessed video stream to a tensor stream on its source pad.
After the inference runtime receives the tensor stream on its sink pad, it runs the inference.
Produces a tensor stream with the inference results on its source pad.
Composes frames by combining content from its sink pads.
Pushes the GStreamer buffers containing these composed frames to its source pad.
Forwards the video stream received on its sink pad to Weston.
Weston renders the video stream on a local display.
