EditedMediaItem.Builder

public Builder(MediaItem mediaItem)

Creates an instance.

For image inputs, the values passed into setRemoveAudio, setRemoveVideo and setFlattenForSlowMotion will be ignored. For multi-picture formats (e.g. gifs), a single image frame from the container is displayed if the DefaultAssetLoaderFactory is used.

public EditedMediaItem build()

Builds an EditedMediaItem instance.

@CanIgnoreReturnValue
public EditedMediaItem.Builder setDurationUs(@IntRange(from = 1) long durationUs)

Sets the MediaItem duration in the output, in microseconds.

For export, this should be set for inputs that don't have an intrinsic duration (e.g. images). It will be ignored for inputs that do have an intrinsic duration (e.g. video).

This should always be set for preview.

If clipping is applied, this should be the duration before clipping.

The default value is the MediaItem's image duration.

@CanIgnoreReturnValue
public EditedMediaItem.Builder setEffects(Effects effects)

Sets the Effects to apply to the MediaItem.

Callers should not interact with underlying audioProcessors.

The default value is EMPTY.

@CanIgnoreReturnValue
public EditedMediaItem.Builder setFlattenForSlowMotion(boolean flattenForSlowMotion)

Sets whether to flatten the MediaItem if it contains slow motion markers.

The default value is false.

See flattenForSlowMotion for more information about slow motion flattening.

If using an ExoPlayerAssetLoader.Factory with a provided , make sure that FLAG_READ_SEF_DATA is set on the Mp4Extractor used. Otherwise, the slow motion metadata will be ignored and the input won't be flattened.

Slow motion flattening is only supported when the Composition contains exactly one MediaItem.

Using slow motion flattening together with MediaItem.ClippingConfiguration is not supported yet.

@CanIgnoreReturnValue
public EditedMediaItem.Builder setFrameRate(@IntRange(from = 0) int frameRate)

Sets the MediaItem frame rate in the output video, in frames per second.

This should be set for inputs that don't have an intrinsic frame rate (e.g., images). It will be ignored for inputs that do have an intrinsic frame rate (e.g., video).

For images, the frame rate depends on factors such as desired look, output format requirement, and whether the content is static or dynamic (e.g., animation). However, 30 fps is suitable for most use cases.

No frame rate is set by default.

@CanIgnoreReturnValue
public EditedMediaItem.Builder setRemoveAudio(boolean removeAudio)

Sets whether to remove the audio from the MediaItem.

The default value is false.

The audio and video cannot both be removed because the output would not contain any samples.

@CanIgnoreReturnValue
public EditedMediaItem.Builder setRemoveVideo(boolean removeVideo)

Sets whether to remove the video from the MediaItem.

The default value is false.

The audio and video cannot both be removed because the output would not contain any samples.
