* Starts an asynchronous operation to export the given {@link Composition}.

+ *
This method is under implementation. Only the {@linkplain Composition compositions} meeting
+ * the below conditions are supported:
*
*
- * - The {@link Composition} must contain exactly one {@link Composition#sequences
- * EditedMediaItemSequence}. Its {@link Composition#effects Effects} must
- *
- * - Contain no {@linkplain Effects#audioProcessors audio effects}.
- *
- Either contain no {@linkplain Effects#videoEffects video effects}, or exactly one
- * {@link Presentation}.
- *
- * - The {@link EditedMediaItem} instances in the {@link EditedMediaItemSequence} must:
- *
- * - have identical tracks of the same format (after {@linkplain
- * EditedMediaItem#removeAudio audio} or {@linkplain EditedMediaItem#removeVideo
- * video} removal and {@linkplain EditedMediaItem#flattenForSlowMotion slow motion
- * flattening}).
- *
- have identical {@link EditedMediaItem#effects Effects} applied.
- *
- not represent an image.
- *
+ * - There must be no overlapping track corresponding to the same track type in the output.
+ * More precisely, the composition must either contain a single {@linkplain
+ * EditedMediaItemSequence sequence}, or contain one audio-only sequence and one
+ * video/image-only sequence.
+ *
- A sequence cannot contain both video and image input.
+ *
- A sequence cannot contain both HDR and SDR video input.
+ *
- A sequence cannot have gaps in its video or image samples. In other words, if a sequence
+ * contains video or image data, it must contain this type of data in the entire sequence.
+ *
- All the {@link EditedMediaItem} instances in a sequence must have the same audio format.
+ *
- All the {@link EditedMediaItem} instances in a sequence must have the same effects
+ * applied.
+ *
- The {@linkplain Composition#effects composition effects} must contain no {@linkplain
+ * Effects#audioProcessors audio effects}.
+ *
- The composition effects must either contain no {@linkplain Effects#videoEffects video
+ * effects}, or exactly one {@link Presentation}.
*

* The export state is notified through the {@linkplain Builder#addListener(Listener)
