Flash Video (FLV) is the name of a file format used to deliver video over the Internet using Adobe Flash Player. The most recent public release of Flash Player supports H.264 video and HE-AAC audio. Flash Video content may also be embedded within SWF files. Notable websites of the Flash Video format include YouTube, Google Video, Yahoo! Video,,, etc.

The M3U8 file extension is used for playlists that are stored in the M3U UTF-8 (Unicode) text playlist format. M3U and M3U8 playlists can be opened in a variety of media players, such as Winamp, KMPlayer, iTunes, VLC media player etc. Playlist doesn’t contain any multimedia content, it is only list of media files selected from a hard disk or other media.


Why should we transcode FLV file to M3U8 format?
This owes to the advantages of M3U8 format. First and foremost, it’s fast to drag the video. There is no extra datas and no need for buffering. In other words, you can drag the video to any point for smoothly playing immediately. What’s more? The original supporting effect is good.

How to convert FLV file to M3U8 format?
You cannot usually change a file extension (like the FLV file extension) to your terminal format like M3U8 and expect the newly renamed file to be usable. Two methods are allowed here:

FFmpeg is a free refined piece of conversion tool for Windows and Linux and it is a command-line tool that allows you to convert virtually any video and audio formats to another format. The good news for Linux users is that the H.265 codec is available in the popular encoding suite “ffmpeg”. Although “ffmpeg” probably exists in your distro’s repositories, it might be out of date or it might not have support for H.265 compiled in. Download either the 32-bit or 64-bit .tar.xz file. If you are unsure which one to download, then use the 32-bit one. In the directory where you downloaded the file, run the following command to unpack the archive file. Although it is realizable to convert FLV file to M3U8 with FFmpeg, the whole process is a bit difficult for our green hands. If you are Mac users, you can turn to “Convert Video to M3U8 with FFmpeg Alternatives for Mac”.

Another popular video converter works well on Windows operation. Pavtube Video Converter (review) is highly recommended. This program is preferable because it’s both easier and will probably result in a more accurate file conversion. It’s specially designed for M3U8 with the upgraded version You can know more about M3U8 upgrade news from Pavtube official website. It’s better than FFmpeg because several steps are enough for this program. It’s indeed easy to use!


A detailed guide is offered here for your information:

Step 1: Download and install the program. Click “Add video” on the main interface to load your FLV files to the program. You can also drag the files to the program’s window list directly. This program can also support the batch video clips.

Step 2: Click the “Format” bar to get the drop-down menu and you can get “HLS Streaming (m3u8)”. Choose “ipad m3u8 streaming” or “iphone m3u8 streaming” as best output format. Any media player supporting TS format are all available for playing M3U8 format files.


Step 3: Click “Settings” button to customize the output video and audio settings by yourself. Video codec is the default H.264 and audio codec is the default AAC. You can change the resolution, bit rate, frame rate as you need. But if you are not good at it, you’d better use the default parameters, they will ensure you a good balance between file size and image quality basically.

Step 4: When everything is done, you can take a preview by hitting “Play” button. If you are satisfied with the final result, you can click “Convert” button to finish the conversion work.

But frankly speaking, if you are not familiar with video to M3U8 conversion, I suggest you to choose the easiest one. Pavtube Video Converter can do you a big favor.
