Using wasmVision

wasmvision run

These are some useful examples of the wasmvision run command.

Automatically download the blur processor, capture from your webcam (default), process the video, and stream the output using MJPEG to port 8080 (default)

wasmvision run -p blur

Automatically download the mosaic processor and the mosaic-9.onnx model, capture from your webcam (default), process the video, and stream the output using MJPEG to port 8080 (default)

wasmvision run -p mosaic

Capture from your webcam (default), process the video using the mosaic.wasm processor located in the default processor directory, and stream the output using MJPEG to port 8080 (default)

wasmvision run -p mosaic.wasm

Capture from your webcam (default), process the video using the yourcustom.wasm processor located in a non-default directory, and stream the output using MJPEG to port 8080 (default)

wasmvision run -p /path/to/processors/yourcustom.wasm

Capture from a secondary webcam, process the video, and stream the output using MJPEG to port 8080 (default)

wasmvision run -s /dev/video2 -p /path/to/processors/mosaic.wasm

Capture from your webcam (default), process the video using 2 processors chained together, and stream the output using MJPEG to port 8080 (default)

wasmvision run -p /path/to/processors/hello.wasm -p /path/to/processors/mosaic.wasm

Capture from a file, process the video, and stream the output using MJPEG to port 6000

wasmvision run -s /path/to/video/filename.mp4 -p /path/to/processors/blur.wasm -o mjpeg -d :6000

Capture from your webcam, process the video, and save the output to a file

wasmvision run -p /path/to/processors/mosaic.wasm -o file -d /path/to/video/filename.avi
