What is WebM?
A WebM file consists of VP8 video and Vorbis audio streams, in a container based on a profile of Matroska. The project releases WebM related software under a BSD license and all users are granted a worldwide, non-exclusive, no-charge, royalty-free patent license. Despite this, concerns have surfaced over potential for infringement on existing patents and some in the industry have called upon Google to provide indemnification against patent suits.
Support by Mozilla Firefox, Opera, and Google Chrome was announced at the 2010 Google I/O conference. Internet Explorer 9 will also be able to support WebM files if the VP8 codec is installed locally. Safari on the desktop supports any codec installed in QuickTime, allowing future WebM playback using QuickTime codec components such as Perian. Epiphany also supports WebM through the GStreamer multimedia framework.
YouTube now offers WebM videos as part of its HTML5 player experiment. All uploaded files with resolutions from 720p and above are encoded to WebM in 480p and 720p, and other resolutions will follow. YouTube has committed to encode their entire portfolio of videos to WebM.
What is M4V?
Apple uses M4V files to encode TV episodes, movies, and music videos in the iTunes Store. The copyright of M4V files may be protected by using Apple's FairPlay DRM copyright protection. To play a protected M4V file, the computer needs to be authorized (using iTunes) with the account that was used to purchase the video. However, unprotected M4V files without AC3 audio may be recognized and played by other video players by changing the file extension from '.m4v' to '.mp4'.
Besides Apple iTunes and Apple QuickTime Player, M4V files can also be opened and played with the version of Windows Media Player included with Windows 7, Media Player Classic, RealNetworks RealPlayer, VideoLAN VLC media player and Nero Showtime (included with Nero Multimedia Suite). The format, with DRM removed, can also be played in the webOS Video Player for use on the Palm Pre, Palm Pixi smartphones. It is also playable by the Android operating system with its video player. It can also be played with the BS Player Pro.
M4V video with FairPlay attached to it is read in QuickTime as AVC0 Media.
