Summary

This Proposal will replace Google's ExoPlayer library with Google's Media3 library for CommunuityToolit.Maui.MediaElement.

Google has provided an official migration guide: https://developer.android.com/guide/topics/media/media3/getting-started/migration-guide

Motivation

Google has officially deprecated ExoPlayer and recommends all developers to move to their new implementation, Media3: https://android-developers.googleblog.com/2023/03/media3-is-ready-to-play.html#:~:text=ExoPlayer%20is%20deprecated%2C%20long%20live%20ExoPlayer!&text=google.,make%20the%20transition%20to%20Media3.

It is unclear which version of Android will cease to support ExoPlayer, but we should prioritize porting MediaElement to Media3 before that happens

Detailed Design

TBD

We are unable to provide a detailed design until we have an Media3 library for .NET MAUI.

Usage Syntax

The public APIs for MediaElement will remain unchanged

Drawbacks

There is not currently a C# Binding for Media3.

I spoke with @martijn00, the owner/maintainer of BaseFlow/XamarinExoPlayer (the NuGet Package that CommunityToolkit.Maui.MediaElement currently uses for ExoPlayer bindings), and he has plans to look into it. Specifically, there is currently an open PR on the XamarinExoPlayer repo adding support for Media3.

I've added the blocked label until a Media3 Binding is available.

Alternatives

There are no alternatives. Media3 is now the only officially supported Media library for Android.

Unresolved Questions

Will XamarinExoPlayer merge the open Media3 Pull Request, or will they create a new library to support Media3?

Will @moljac create a new library for the Media3 bindings? xamarin/AndroidX#710 (comment)

Moljac was a good boy and started bindings in March:

dotnet/android-libraries#779

I have 1 artifact with approx 50-60 errors to fix. I think this should not be too long.

Update from @moljac on the Media3 binding:

Almost done. Few weird issues I am investigating, but...
