video_player_web

The web implementation of video_player.

Usage

This package is endorsed, which means you can simply use video_player normally. This package will be automatically included in your app when you do, so you do not need to add it to your pubspec.yaml.

However, if you import this package to use any of its APIs directly, you should add it to your pubspec.yaml as usual.

Limitations on the Web platform

Video playback on the Web platform has some limitations that might surprise developers more familiar with mobile/desktop targets.

In no particular order:

dart:io

The web platform does not suppport dart:io, so attempts to create a VideoPlayerController.file will throw an UnimplementedError.

Autoplay

Attempts to start playing videos with an audio track (or not muted) without user interaction with the site ("user activation") will be prohibited by the browser and cause runtime errors in JS.

Some videos restart when using the seek bar/progress bar/scrubber

Certain videos will rewind to the beginning when users attempt to seekTo (change the progress/scrub to) another position, instead of jumping to the desired position. Once the video is fully stored in the browser cache, seeking will work fine after a full page reload.

The most common explanation for this issue is that the server where the video is stored doesn't support HTTP range requests.

NOTE: Flutter web's local server (the one that powers flutter run) DOES NOT support range requests, so all video assets in debug mode will exhibit this behavior.

See Issue #49360 for more information on how to diagnose if a server supports range requests or not.

Mixing audio with other audio sources

The VideoPlayerOptions.mixWithOthers option can't be implemented in web, at least at the moment. If you use this option it will be silently ignored.

Supported Formats

Different web browsers support different sets of video codecs.
