`mediaCrypto` is initialized before `codec` in `maybeInitCodecOrBypass`. Before this change, it was possible for `maybeInitCodecOrBypass` to complete with `mediaCrypto != null` and `codec == null`, in particular if it was run as part of clearing the player surface (since in that case, no video codec is initialized). This inconsistent state then causes issues during a later invocation of `maybeInitCodecOrBypass`, when `mediaCrypto` is still non-null, and `mediaCryptoRequiresSecureDecoder = true`, but the content has been changed to unencrypted with no associated DRM session. This results in a playback error, because a secure decoder is initialized but there's no DRM session available to work with it. This change ensures that when `maybeInitCodecOrBypass` completes, either both `mediaCrypto != null` and `codec != null` (i.e. codec initialization was completed) or `mediaCrypto == null` and `codec == null` (i.e. codec initialization was not completed). We also ensure that when nulling out `mediaCrypto` we also set `maybeInitCodecOrBypass = false`. A later change should be able to demote `maybeInitCodecOrBypass` from a field to a local in order to remove any risk of that part of state becoming out of sync. This resolves the issue, because during the second invocation of `maybeInitCodecOrBypass` an insecure decoder is now (correctly) initialized and the unencrypted content is successfully played. #minor-release PiperOrigin-RevId: 587713911
ExoPlayer module
This module provides ExoPlayer, the Player implementation for local media
playback on Android.
Getting the module
The easiest way to get the module is to add it as a gradle dependency:
implementation 'androidx.media3:media3-exoplayer:1.X.X'
where 1.X.X is the version, which must match the version of the other media
modules being used.
Alternatively, you can clone this GitHub project and depend on the module locally. Instructions for doing this can be found in the top level README.
