usage cannot be changed after creation. The AudioRenderUsage2 value is used by audio policy
to dictate how audio streams interact with each other. This enum expands the original (strict)
enum |AudioRenderUsage| with additional stream types. AudioRendererEvent AudioRendererRequest AudioRenderers can be in one of two states at any time: configurable or operational . A
renderer is considered operational whenever it has packets queued to be rendered; otherwise it
is configurable . Once an AudioRenderer enters the operational state, calls to “configuring”
methods are disallowed and will cause the audio service to disconnect the client’s connection.
The following are considered configuring methods: AddPayloadBuffer, SetPcmStreamType,
SetStreamType, SetPtsUnits, SetPtsContinuityThreshold. AudioRequest AudioSampleFormat Enumerates the supported audio sample formats. AudioUncompressedFormat AudioUncompressedFormat Behavior CodecProfile A list of permitted codec profiles. This list should be flexible since codecs can and will be added
in the future. This can contain both video and audio profiles if needed. ColorSpace CryptoFormat CryptoFormat DomainFormat DomainFormat EncoderSettings Settings for encoders that tell them how to encode raw

specific presentation timestamp. The effective presentation time of such a
packet depends on the context in which the StreamPacket is used. RENDER_USAGE2_COUNT RENDER_USAGE_COUNT STREAM_PACKET_FLAG_DISCONTINUITY Indicates a discontinuity in an otherwise continuous-in-time sequence of
packets. The precise semantics of this flag depend on the context in which
the StreamPacket is used. STREAM_PACKET_FLAG_DROPPABLE Indicates that all other packets in the stream can be understood without
reference to this packet. This is typically used in compressed streams to
identify packets containing frames that may be discarded without affecting
other frames. STREAM_PACKET_FLAG_KEY_FRAME Indicates that the packet can be understood without reference to other
packets in the stream. This is typically used in compressed streams to
identify packets that contain key frames. VIDEO_ENCODING_H263 Video encodings.
