IdlingMediaCodecAdapterFactory

Artifact: androidx.media3:media3-test-utils-robolectric

Kotlin |Java

@UnstableApi
class IdlingMediaCodecAdapterFactory : MediaCodecAdapter.Factory

A MediaCodecAdapter.Factory which can idle all the async queueing and callback threads used in async MediaCodec mode.

This helps ensure that buffers are reliably queued and dequeued from MediaCodec as the playback thread advances in tests. Without this, the queueing and callback threads run freely and often make little progress before the test completes, leading to flakiness and unpredictable results.

Summary

Public constructors
`IdlingMediaCodecAdapterFactory(context: Context!)` Constructs an instance with no automatic idling.
`IdlingMediaCodecAdapterFactory(context: Context!, clock: Clock!)` Constructs an instance which automatically idles the async threads using `clock`.

Public functions
`MediaCodecAdapter!`	`createAdapter(configuration: MediaCodecAdapter.Configuration!)` Creates a `MediaCodecAdapter` instance.
`Unit`	`idleQueueingAndCallbackThreads()` Calls `idle` on all created queueing and callback threads with a non-null `looper`.
