Without this the annotation isn't shown in javadoc (same in Dackka)

No annotation:
https://exoplayer.dev/doc/reference/com/google/android/exoplayer2/source/DefaultMediaSourceFactory.html#getSupportedTypes()

Annotation present:
https://exoplayer.dev/doc/reference/com/google/android/exoplayer2/source/MediaSource.Factory.html#getSupportedTypes()
