FLV
FLV is the acronym for Flash Video.
Flash Video
A file format used for delivering video content over the internet. Developed by Adobe (formerly Macromedia), FLV files are primarily associated with Adobe Flash Player, a web browser plugin for playing multimedia content such as videos, animations, and interactive applications.
Here are some key points about FLV:
- Video Compression: FLV files use compression algorithms to compress video data while maintaining acceptable visual quality efficiently. One of the common video codecs used within FLV files is the Sorenson Spark codec.
- Streaming Capability: FLV files are designed for streaming video content over the internet. This makes them suitable for delivering videos in real-time, allowing viewers to watch videos while the content is being downloaded.
- Interactive Elements: FLV files can include interactive elements such as clickable buttons, animations, and scripted content, making them versatile for creating interactive multimedia experiences.
- Supported by Flash Player: To play FLV files, users typically need Adobe Flash Player installed in their web browsers. However, many modern browsers have phased out support for Flash due to security concerns, favoring HTML5 for multimedia content delivery.
- Web Video: In the past, FLV was a popular format for embedding videos on websites and delivering video content on platforms like YouTube. However, with the decline of Flash and the rise of HTML5, other video formats like MP4 have become more common for web-based video delivery.
- Conversion and Compatibility: FLV files can be converted to other formats for wider compatibility. Many online video converters can convert FLV videos to formats like MP4 or AVI.
- Security Concerns: Due to security vulnerabilities and the decline of Adobe Flash, many platforms and browsers have discontinued support for Flash content, including FLV files. As a result, FLV has become less relevant for modern web development.
As the internet landscape evolves, the usage of FLV files has diminished, and alternative video formats compatible with HTML5, such as MP4, have become more prevalent for delivering video content on the web.
