Video Fingerprinting SDK .Net / C++

A video fingerprint is a compact digital descriptor that can be extracted from any video source, whether it is a fragment of a TV broadcast, a video file, an online video, or from a DVD or Blu-ray Disk. These video fingerprints can then be stored, copied, and compared. Video fingerprints can be used to identify copyrighted video material, identify duplicate videos, search for videos, organize videos, recognize when a specific video is played, media monitoring, or ad tracking.

Use VisioForge Video Duplicates Finder as a sample application to find similar video files.

Use VisioForge Media Monitoring Tool as a sample application to find one video fragment (TV commercial, for example) in another (full broadcast recording).

.Net SDK version has a helper for MongoDB usage as fingerprint storage.

• An online video hosting service, such as YouTube, could use video fingerprints to avoid copyright infringement. A database of video fingerprints of the copyrighted material would be developed and compared to the video fingerprints materials submitted by users to prevent the illegal submission of pirated videos.
• A video archive service could use video fingerprints to save space and block duplicate uploads. A video fingerprint would be extracted from each video in the archive. The video fingerprint of each new submission would be compared to the database of the fingerprints of existing videos, checking to make sure they are different and blocking duplicate submissions.
• Video Organizer software could use video fingerprints to identify copies of the same movie or video clip, despite differences in format, resolution, or bit-rate, and group them together.
• Set-top box software could use video fingerprints to develop interactive advertisements by identifying when specific TV ads are shown and displaying a clickable URL to allow the user to access the product website. It could also be used to keep track of how often the ad is viewed.
• A search engine for videos could be developed using our Video Fingerprinting SDK – a unique, revolutionary service implementing a video-by-video search functionality that would be the first of its kind.
• A TV Clipping Service could use video fingerprinting technology to automate TV broadcast monitoring and TV ad verification to detect when a client’s ad is aired so they can ensure the terms of their TV advertising agreements are being respected.
• We have developed our media monitoring tool as a fully functional application that enables the detection of ad samples in a broadcast dump to implement just this type of service. This application, including sources, can be licensed separately and used as a basis for building your product or integrated into an existing system. See our media monitoring tool page for more information.
• Detecting pirated video content

• C++ SDK supports Windows and Linux, or any other POSIX-compatible operating system (available by request)
• .Net SDK supports Windows 7 and later

Each second of a video stream analyzed requires about 1kb for its video fingerprint. Duplicate detection generally only requires 3-5 seconds of each video to be indexed. Indexing of full videos is required in order to identify a video that has been included inside another.

Indexing one second of video takes about 300 milliseconds – the actual processing of the file accounts for about half of that time (150 milliseconds), while video decompression accounts for the rest. Matching a pair of 10 second long fingerprints takes 1-2 milliseconds. These times were established by testing with an Intel i3 processor and LAV filters for video compression.

• C++: No. You will need some other library (FFMPEG, for example, demo available) in order to implement video reading in your application
• .Net: Yes, FFMPEG and libVLC included. Also, system codecs can be used for decoding

The following code samples are included with your purchase:

C++:

• FFMPEG-based console application that indexes videos and builds fingerprints (Windows, Linux)
• A console application that compares two fingerprints to detect duplicates (Windows, Linux)
• A console application that searches for entries of one fingerprint inside another (Windows, Linux)
• Source code of a full Media Monitoring Tool application (Windows, Linux)

.Net:

• Media Monitoring Tool and Media Monitoring Tool Live source code
• Video Duplicates Finder source code.

C++:

• VFCompare API – a video fingerprinting algorithm implementation that is optimized for the detection of duplicate videos

• VFSearch API – a video fingerprinting algorithm implementation that is optimized for searching video in video

.Net:

• Full API described in a help file.

We suggest you download and experiment with the trial versions of our Media Monitoring Tool application, Video Duplicates Finder application, as well as familiarizing yourself with the API and code samples.
