Convert FLV to M4V
About FLV
FLV (Flash Video) is a container format that was used to deliver video over the Internet using the Adobe Flash Player. For many years, it was the de facto standard for web video, used by sites like YouTube and Hulu. However, with the decline of Flash due to security issues and the rise of HTML5 video, FLV is now a deprecated and obsolete format.
About M4V
The M4V file format is a video container format developed by Apple and is very similar to the MP4 format. In fact, they are often interchangeable. The primary difference is that M4V files may optionally be protected by Apple's FairPlay DRM copy protection, which is used for videos purchased or rented from the iTunes Store.

Frequently Asked Questions
Is Flash completely dead?
Yes, Adobe officially ended support for Flash Player at the end of 2020, and all major browsers have removed it. While FLV files can still be played in some media players like VLC, the technology is considered obsolete and should not be used for new content.
Why was Flash replaced by HTML5?
Flash was replaced because it was a proprietary plugin that suffered from poor performance, security vulnerabilities, and a lack of support on mobile devices. HTML5 video is a web standard that is built directly into browsers, making it more secure, efficient, and universally compatible.
What's the difference between M4V and MP4?
Functionally, they are nearly identical. An M4V file without DRM can be renamed to .mp4 and will play without issues. The .m4v extension is primarily used by Apple to identify videos for its ecosystem (iTunes, Apple TV), especially those that contain DRM or AC3 audio.
Can I play M4V files on non-Apple devices?
If the M4V file is not protected by DRM, it will play on most devices and players that support MP4. If the file is protected with FairPlay DRM, it can only be played on authorized devices, such as those signed into the Apple ID that purchased the video.
