Summary

Public fields
`long`	`subsampleOffsetUs` An offset that must be added to the metadata's timestamps after it's been decoded, or `OFFSET_SAMPLE_RELATIVE` if `timeUs` should be added.

Public constructors
`MetadataInputBuffer()`

`static final int`	`BUFFER_REPLACEMENT_MODE_DIRECT = 2` Allows buffer replacement using `allocateDirect`.
`static final int`	`BUFFER_REPLACEMENT_MODE_DISABLED = 0` Disallows buffer replacement.
`static final int`	`BUFFER_REPLACEMENT_MODE_NORMAL = 1` Allows buffer replacement using `allocate`.

`final CryptoInfo`	`cryptoInfo` `CryptoInfo` for encrypted data.
`@Nullable ByteBuffer`	`data` The buffer's data, or `null` if no data has been set.
`@Nullable Format`	`format` The `Format`.
`@Nullable ByteBuffer`	`supplementalData` Supplemental data related to the buffer, if `hasSupplementalData` returns true.
`long`	`timeUs` The time at which the sample should be presented.
`boolean`	`waitingForKeys` Whether the last attempt to read a sample into this buffer failed due to not yet having the DRM keys associated with the next sample.

`final void`	`addFlag(@C.BufferFlags int flag)` Adds the `flag` to this buffer's flags.
`final void`	`clearFlag(@C.BufferFlags int flag)` Removes the `flag` from this buffer's flags, if it is set.
`final boolean`	`getFlag(@C.BufferFlags int flag)` Returns whether the specified flag has been set on this buffer.
`final boolean`	`hasSupplementalData()` Returns whether the `BUFFER_FLAG_HAS_SUPPLEMENTAL_DATA` flag is set.
`final boolean`	`isEndOfStream()` Returns whether the `BUFFER_FLAG_END_OF_STREAM` flag is set.
`final boolean`	`isFirstSample()` Returns whether the `BUFFER_FLAG_FIRST_SAMPLE` flag is set.
`final boolean`	`isKeyFrame()` Returns whether the `BUFFER_FLAG_KEY_FRAME` flag is set.
`final boolean`	`isLastSample()` Returns whether the `BUFFER_FLAG_LAST_SAMPLE` flag is set.
`final boolean`	`notDependedOn()` Returns whether the `BUFFER_FLAG_NOT_DEPENDED_ON` flag is set.
`final void`	`setFlags(@C.BufferFlags int flags)` Replaces this buffer's flags with `flags`.

`void`	`clear()` Clears the buffer.
`void`	`@EnsuresNonNull(value = "data") ensureSpaceForWrite(int length)` Ensures that `data` is large enough to accommodate a write of a given length at its current position.
`final void`	`flip()` Flips `data` and `supplementalData` in preparation for being queued to a decoder.
`final boolean`	`isEncrypted()` Returns whether the `BUFFER_FLAG_ENCRYPTED` flag is set.
`static DecoderInputBuffer`	`newNoDataInstance()` Returns a new instance that's not able to hold any data.
`void`	`@EnsuresNonNull(value = "supplementalData") resetSupplementalData(int length)` Clears `supplementalData` and ensures that it's large enough to accommodate `length` bytes.
