How FLV Files Work

Flash Video (FLV) files have been a cornerstone of internet video content for many years. The structure of these files is quite complex, but it's this complexity that has allowed them to deliver high-quality video content efficiently. At the heart of an FLV file are two key components: codecs and metadata. Codecs are the software used to encode and decode the video and audio data. FLV files typically use the Sorenson Spark or VP6 video codec and the MP3 or AAC audio codec. These codecs are known for their balance of quality and compression, enabling FLV files to deliver good video quality without consuming excessive bandwidth.

The second key component of an FLV file is its metadata. This is data about the video, such as its duration, dimensions, and keyframe intervals. This metadata is crucial for the efficient streaming of the video. It allows the video player to know in advance how to handle the video data, ensuring smooth playback. The combination of efficient codecs and detailed metadata has made FLV files a popular choice for streaming video content. However, the technology that enabled this efficient streaming is now somewhat outdated. Modern streaming technologies, such as HTTP Live Streaming (HLS) and Dynamic Adaptive Streaming over HTTP (DASH), offer more efficient and reliable streaming, especially for live video content.
