How to Extract Audio and Video from FLV Files with FLV Extract
FLV files are a common format for streaming video on the web. They can contain both audio and video data, but sometimes you may want to extract only one of them for your own purposes. For example, you may want to save the audio track of a FLV video as a MP3 file, or convert the video to a different format. In this article, we will show you how to use a free and simple tool called FLV Extract to extract audio and video from FLV files without decompressing or recompressing them.
What is FLV Extract
FLV Extract is a free, open-source software that allows you to extract audio and video from .FLV (flash video) files. It supports H.263, H.264, VP6, and AAC codecs. It does not decompress or recompress the data, so it preserves the original quality and saves time and disk space. You can download FLV Extract from http://www.moitah.net/ [^3^]. It is a portable application, so you do not need to install it. Just unzip the downloaded file and run FLVExtract.exe.
How to use FLV Extract
Using FLV Extract is very easy. Just follow these steps:
Open FLV Extract and select which of the three elements you want to extract: audio, video, or timestamps. You can select more than one element if you want.
Drag and drop the .FLV file(s) that you want to process onto the FLV Extract window. You can also use the File menu to add files.
Wait for the extraction process to finish. You will see a progress bar and a log window showing the details of each file.
Find the extracted files in the same folder as the original .FLV file(s). The audio files will have the extension .mp3, .aac, .speex, or .wav depending on the codec. The video files will have the extension .avi or .264 depending on the codec. The timestamp files will have the extension .txt.
That's it! You have successfully extracted audio and video from FLV files with FLV Extract.
