Video playback in Web

Unity Web supports video playback using the VideoPlayer API. This page provides information only about the video playback capabilities that Web supports. To learn how to use video with your Unity application, refer to the Video Player.

Video player

You can use the Video Player component to control how to time video playback relative to other interactive behaviors in Web. For more information, refer to the Clock management with the Video Player component.

The only exceptions are:

  • Web doesn’t support frame accuracy.
  • The VideoPlayer component doesn’t support synchronous playback with captureFramerate. By default, it uses the normal asynchronous playback that’s described with the Game time update mode.

Supported video playback features and formats

Unity Web supports the following video playback audio output modes:

クラス 使用
VideoAudioOutputMode.None Disables the embedded audio.
VideoAudioOutputMode.Direct Sends the embedded audio directly to the platform’s audio hardware.
VideoAudioOutputMode.AudioSource Sends the embedded audio into a specified AudioSource. If you set the output mode to VideoAudioOutputMode.AudioSource, Unity ignores all AudioSource fields except mute. This is because 3D spatialization of video playback isn’t available on the web.

Video formats

Unity supports the following common video file formats:

形式 拡張子
MPEG–4 Part 14 .mp4
MPEG–4 file used for video downloaded from the Apple iTunes store .m4v
Apple’s QuickTime movie format .mov
Moving Picture Experts Group (MPEG) .mpg
MPEG video .mpeg
WebM video .webm
Ogg video file .ogv

The only exception to this restriction is if the video URL has no file name extension, in which case, the browser plays the video without any restrictions.

Video clips

VideoClips aren’t supported on Web. Typically, when creating a scene, you import a VideoClip to your Unity project using VideoClipImporter, which is convenient if you want to reuse the same VideoClip across several platforms. When building a Web game that has VideoClip attached however, the Unity console logs the following warning for each VideoClip found in the game:

Embedded video clips are not supported by the Web player: %s. \nUse the Video Player component's URL option instead. Where %s is replaced by the video clip name. At runtime, if your game has VideoClips assigned, then Unity logs a warning message in the developer console of your web browser.
