What is FLV file?

File with FLV extension is a container that contains encoded audio and video data. The file stores data in similar format as that used by SWF, a multimedia streaming file format based on Adobe Flash technology. FLV file format uses the same compression methods as SWF, namely:

  • audio data:
    • MP3,
    • ADPCM,
    • Nellymoser,
    • Speex,
    • AAC – with some restrictions;
  • video data:
    • On2 VP6,
    • Sorenson Spark (H.263),
    • Screen video,
    • Screen video 2,
    • H.264 – with some restrictions.

FLV file structure consists of a header and packets. The header is 3-byte long and stores file’s signature, and rest of the file stores actual contents. FLV format is used for streaming data (on YouTube service, for example). FLV file can be embedded in SWF file. The FLV format is supported by many media player tools and web browsers (a dedicated plugin is required). FLV files can be converted into other multimedia formats. FLV format was developed in 2003, while in 2007 its successor, a brand new format based on MPEG-4 part 12 standard and ACC (audio) designated F4V, was introduced.

We hope we helped you solve the problem with the FLV file. If you do not know where you can download the application from our list, click on the link (which is the name of the program) - you will find more information there on the location where to download the secure setup version of the required application.

What else may cause problems?

There can be more reasons which determine that you are not able to open the FLV file (apart from the lack of the proper application installed).

First - the FLV file may be incorrectly associated with the application installed to support it. In this case, you need to change this association by yourself. To do this, right-click on the FLV file that you want to edit, click "Open with" and then select the program from the list that you have installed. After this operation, the problems with opening the FLV file should be solved.

Second - the file you want to open can simply be damaged. Then, the best solution is to find a new version of given file, or download it again from the same source as before (maybe for some reason in the previous session the download of the FLV file has not been completed and it cannot be opened properly).
