Video fingerprinting
Media fingerprinting uses advanced technology to create a unique and stable identity for a video. This identity, known as a fingerprint, remains unchanged even when the video file is converted, edited, compressed, or rotated. This feature is useful for scenarios such as duplicate video detection and copyright protection. This topic provides API call examples for media fingerprinting using the ApsaraVideo VOD software development kit (SDK) for Java. The examples show how to submit media fingerprint jobs, query media fingerprint jobs, and obtain media fingerprint results.
