Deprecated. com.google.android.exoplayer2 is deprecated. Please migrate to androidx.media3 (which contains the same ExoPlayer code). See the migration guide for more details, including a script to help with the migration.

An AssetLoader implementation that loads videos from traditional GLES texture instances.

Typically instantiated in a custom AssetLoader.Factory saving a reference to the created TextureAssetLoader. Input is provided calling queueInputTexture(int, long) to provide all the video frames, then signalling the end of input when finished.

queueInputTexture

public boolean queueInputTexture​(int texId,
                                 long presentationTimeUs)

Deprecated.

Attempts to provide an input texture.

Must be called on the same thread as signalEndOfVideoInput().

Parameters:texId - The ID of the texture to queue.presentationTimeUs - The presentation time for the texture, in microseconds.Returns:Whether the texture was successfully queued. If false, the caller should try again later.

signalEndOfVideoInput

public void signalEndOfVideoInput()

Deprecated.

Signals that no further input frames will be rendered.

Must be called on the same thread as queueInputTexture(int, long).
