15. A non-transitory computer-readable storage medium comprising computer-readable instructions that, in response to execution, cause a processor to perform operations, comprising: receiving a first media content item that comprises first low-level audio features and first video content having first low-level video features; determining that the first media content item belongs to a first genre of a plurality of genres based on first side channel information, wherein the first side channel information is based at least on the first low-level audio features and the first low-level video features; receiving a second media content item that comprises second audio content having second low-level audio features and second low-level video features; determining that the second media content item belongs to the first genre of the plurality of genres based on second side channel information, wherein the second side channel information is based at least on the second low-level audio features and the second low-level video features; generating a first fingerprint based on the first audio content; in response to determining that the first media content item belongs to the first genre, selecting, based on the first genre, a plurality of audio fingerprints that are associated with the first genre, wherein the selected plurality of audio fingerprints includes a second fingerprint that is based on the second audio content; determining a matching score between the first media content item and the second media content item by comparing the first audio fingerprint of the first audio content and the second audio fingerprint of the second audio content; determining a rate of false-positive matches between media content items that belong to the first genre; applying a weight to the matching score based on the rate of false-positive matches; determining, based on the weighted matching score, that the first audio content matches the second audio content; determining that the second audio content contains copyrighted content, wherein the copyrighted content is associated with a copyright owner; and notifying the copyright owner that the first media content item matches the second media content item.
15. A non-transitory computer-readable storage medium comprising computer-readable instructions that, in response to execution, cause a processor to perform operations, comprising: receiving a first media content item that comprises first low-level audio features and first video content having first low-level video features; determining that the first media content item belongs to a first genre of a plurality of genres based on first side channel information, wherein the first side channel information is based at least on the first low-level audio features and the first low-level video features; receiving a second media content item that comprises second audio content having second low-level audio features and second low-level video features; determining that the second media content item belongs to the first genre of the plurality of genres based on second side channel information, wherein the second side channel information is based at least on the second low-level audio features and the second low-level video features; generating a first fingerprint based on the first audio content; in response to determining that the first media content item belongs to the first genre, selecting, based on the first genre, a plurality of audio fingerprints that are associated with the first genre, wherein the selected plurality of audio fingerprints includes a second fingerprint that is based on the second audio content; determining a matching score between the first media content item and the second media content item by comparing the first audio fingerprint of the first audio content and the second audio fingerprint of the second audio content; determining a rate of false-positive matches between media content items that belong to the first genre; applying a weight to the matching score based on the rate of false-positive matches; determining, based on the weighted matching score, that the first audio content matches the second audio content; determining that the second audio content contains copyrighted content, wherein the copyrighted content is associated with a copyright owner; and notifying the copyright owner that the first media content item matches the second media content item. 16. The non-transitory computer-readable storage medium of claim 15 , the operations further comprising: training classifiers based on a set of audio features derived from a plurality of media content items; and performing classification on the first low-level audio features of the first media content item and the second low-level audio features of the second media content item as a result of the trained classifiers.
