What is an M4V file?
The M4V file format is a video container format developed by Apple Inc., derived directly from the MPEG-4 Part 14 (MP4) specification. It is primarily utilized to encode video files-such as movies, TV episodes, and music videos-distributed through the Apple iTunes Store. Functionally similar to MP4, M4V files frequently employ Apple's FairPlay DRM (Digital Rights Management) protection to prevent unauthorized reproduction, though unprotected files exist. The container typically encapsulates H.264 or H.265 (HEVC) video data alongside AAC or Dolby Digital (AC-3) audio streams.
How to open an M4V file
Files protected by FairPlay DRM can only be decrypted and opened using Apple QuickTime Player or the Apple TV app on authorized devices associated with the purchasing Apple ID. Unprotected M4V files function identically to standard MP4 files and are natively supported on macOS. On Windows and Linux, unprotected M4V files can be opened by renaming the extension to .mp4 or by using cross-platform media players like VLC Media Player and MPC-HC without modification.

What is a WMA file?
Windows Media Audio (WMA) refers to a series of audio codecs and their corresponding Microsoft container format, designed as a competitor to MP3 and RealAudio. The standard WMA codec is lossy, but the format family includes WMA Lossless, WMA Pro (multichannel), and WMA Voice. It utilizes the Advanced Systems Format (ASF) container structure and supports digital rights management (DRM), which historically restricted playback to authorized Windows devices.
How to open a WMA file
WMA files are native to the Windows ecosystem and open by default in Windows Media Player and Movies & TV. macOS users require third-party components like Flip4Mac (legacy) or universal players such as VLC Media Player and Elmedia Player to decode the stream. Android and Linux support is generally provided via VLC or by installing ffmpeg-based media libraries.
