This CLAMS app wraps PySceneDetect and performs shot boundary detection on input videos.
A shot boundary is a place where one camera shot ends and another begins. The app detects shot boundaries and outputs a list of timestamps where the shot boundaries occur.
General user instruction for CLAMS apps is available at CLAMS Apps documentation.
The Python dependencies are installed from requirements.txt.
OpenCV (cv2) is pulled in automatically as a dependency of PySceneDetect (opencv-python), so you do not install OpenCV yourself.
The opencv-python wheel does, however, link against two OS-level shared libraries that it does not bundle, so they must be present on the host:
libGL.so.1(OpenGL) -- on Debian/Ubuntu,apt-get install -y libgl1libgthread-2.0.so.0(GLib) -- on Debian/Ubuntu,apt-get install -y libglib2.0-0
The provided Containerfile already installs both, so this only matters when running the app outside the container (e.g. bare-metal development).
Although all CLAMS apps are supposed to run as stateless HTTP servers, some apps can configured at request time using URL query strings. For runtime parameter supported by this app, please visit CLAMS App Directory and look for the app name and version.
