Abstract: Methods, systems, and media for identifying content in stereoscopic videos and, more particularly, for detecting abusive stereoscopic videos by generating fingerprints for multiple portions of a video frame are provided. The method comprises: receiving, from a user device, a video content item for uploading to a content provider; selecting a frame from a plurality of frames of the video content item for generating one or more fingerprints corresponding to the video content item; generating a first fingerprint corresponding to the selected frame, a second fingerprint corresponding to a first encoded portion of the selected frame, and a third fingerprint corresponding to a second encoded portion of the selected frame; comparing each of the first fingerprint, the second fingerprint, and the third fingerprint to a plurality of reference fingerprints corresponding to reference video content items; determining whether at least one of the first fingerprint, the second fingerprint, and the third fingerprint match a reference fingerprint of the plurality of reference fingerprints; and, in response to determining that at least one of the first fingerprint, the second fingerprint, and the third fingerprint match the reference fingerprint, causing an indication of the match to be presented on the user device.

Abstract: A first segment of a probe media item that is transmitted as a first live-stream of an event is received. After a first delay period, whether the first segment of the probe media item is similar to a first segment of a first reference media item that is transmitted as a second live-stream of the event and received subsequent to the probe media item is determined. Responsive to determining, after the first delay period, that the first segment is similar to the first segment of the first reference media item, a remedial action in association with the probe media item is performed.
