/// AudioCapturer
///
/// An AudioCapturer is an interface returned from an fuchsia.media.Audio's
/// CreateAudioCapturer method, which may be used by clients to capture audio
/// from either the current default audio input device, or the current default
/// audio output device depending on the flags passed during creation.
///
/// **Format support**
///
/// See (Get|Set)StreamType below. By default, the captured stream type will be
/// initially determined by the currently configured stream type of the source
/// that the AudioCapturer was bound to at creation time. Users may either fetch
/// this type using GetStreamType, or they may choose to have the media
/// resampled or converted to a type of their choosing by calling SetStreamType.
/// Note: the stream type may only be set while the system is not running,
/// meaning that there are no pending capture regions (specified using CaptureAt)
/// and that the system is not currently running in 'async' capture mode.
///
/// **Buffers and memory management**
///
/// Audio data is captured into a shared memory buffer (a VMO) supplied by the
/// user to the AudioCapturer during the AddPayloadBuffer call. Please note the
/// following requirements related to the management of the payload buffer.
///
/// + The payload buffer must be supplied before any capture operation may
///   start. Any attempt to start capture (via either CaptureAt or
///   StartAsyncCapture) before a payload buffer has been established is an
///   error.
/// + The payload buffer may not be changed while there are any capture
///   operations pending.
/// + The stream type may not be changed after the payload buffer has been set.
/// + The payload buffer must be an integral number of audio frame sizes (in
///   bytes)
/// + When running in 'async' mode (see below), the payload buffer must be at
///   least as large as twice the frames_per_packet size specified during
///   StartAsyncCapture.
/// + The handle to the payload buffer supplied by the user must be readable,
///   writable, mappable and transferable.
/// + Users should always treat the payload buffer as read-only.
///
/// **Synchronous vs. Asynchronous capture mode**
///
/// The AudioCapturer interface can be used in one of two mutually exclusive
/// modes: Synchronous and Asynchronous. A description of each mode and their
/// tradeoffs is given below.
///
/// **Synchronous mode**
///
/// By default, AudioCapturer instances are running in 'sync' mode. They will
/// only capture data when a user supplies at least one region to capture into
/// using the CaptureAt method. Regions supplied in this way will be filled in
/// the order that they are received and returned to the client as StreamPackets
/// via the return value of the CaptureAt method. If an AudioCapturer instance
/// has data to capture, but no place to put it (because there are no more
/// pending regions to fill), the next payload generated will indicate that their
/// has been an overflow by setting the Discontinuity flag on the next produced
/// StreamPacket. Synchronous mode may not be used in conjunction with
/// Asynchronous mode. It is an error to attempt to call StartAsyncCapture while
/// the system still regions supplied by CaptureAt waiting to be filled.
///
/// If a user has supplied regions to be filled by the AudioCapturer instance in
/// the past, but wishes to reclaim those regions, they may do so using the
/// DiscardAllPackets method. Calling the DiscardAllPackets method will cause
/// all pending regions to be returned, but with `NO_TIMESTAMP` as their
/// StreamPacket's PTS. See "Timing and Overflows", below, for a discussion of
/// timestamps and discontinuity flags. After a DiscardAllPackets operation,
/// an OnEndOfStream event will be produced. While an AudioCapturer will never
/// overwrite any region of the payload buffer after a completed region is
/// returned, it may overwrite the unfilled portions of a partially filled
/// buffer which has been returned as a result of a DiscardAllPackets operation.
///
/// **Asynchronous mode**
///
/// While running in 'async' mode, clients do not need to explicitly supply
/// shared buffer regions to be filled by the AudioCapturer instance. Instead, a
/// client enters into 'async' mode by calling StartAsyncCapture and supplying a
/// callback interface and the number of frames to capture per-callback. Once
/// running in async mode, the AudioCapturer instance will identify which
/// payload buffer regions to capture into, capture the specified number of
/// frames, then deliver those frames as StreamPackets using the OnPacketCapture
/// FIDL event. Users may stop capturing and return the AudioCapturer instance to
/// 'sync' mode using the StopAsyncCapture method.
///
/// It is considered an error to attempt any of the following operations.
///
/// + To attempt to enter 'async' capture mode when no payload buffer has been
///   established.
/// + To specify a number of frames to capture per payload which does not permit
///   at least two contiguous capture payloads to exist in the established
///   shared payload buffer simultaneously.
/// + To send a region to capture into using the CaptureAt method while the
///   AudioCapturer instance is running in 'async' mode.
/// + To attempt to call DiscardAllPackets while the AudioCapturer instance is
///   running in 'async' mode.
/// + To attempt to re-start 'async' mode capturing without having first
///   stopped.
/// + To attempt any operation except for SetGain while in the process of
///   stopping.
///
/// **Synchronizing with a StopAsyncCapture operation**
///
/// Stopping asynchronous capture mode and returning to synchronous capture mode
/// is an operation which takes time. Aside from SetGain, users may not call any
/// other methods on the AudioCapturer interface after calling StopAsyncCapture
/// (including calling StopAsyncCapture again) until after the stop operation has
/// completed. Because of this, it is important for users to be able to
/// synchronize with the stop operation. Two mechanisms are provided for doing
/// so.
///
/// The first is to use StopAsyncCapture (not the NoReply variant). When the user's
/// callback has been called, they can be certain that stop operation is complete
/// and that the AudioCapturer instance has returned to synchronous operation
/// mode.
///
/// The second way to determine that a stop operation has completed is to use the
/// flags on the packets which get delivered via the user-supplied
/// AudioCapturerCallback interface after calling StopAsyncCapture. When
/// asked to stop, any partially filled packet will be returned to the user, and
/// the final packet returned will always have the end-of-stream flag (kFlagsEos)
/// set on it to indicate that this is the final frame in the sequence. If
/// there is no partially filled packet to return, the AudioCapturer will
/// synthesize an empty packet with no timestamp, and offset/length set to zero,
/// in order to deliver a packet with the end-of-stream flag set on it. Once
/// users have seen the end-of-stream flag after calling stop, the AudioCapturer
/// has finished the stop operation and returned to synchronous operating mode.
///
/// **Timing and Overflows**
///
/// All media packets produced by an AudioCapturer instance will have their PTS
/// field filled out with the capture time of the audio expressed as a timestamp
/// given by the reference clock timeline. Note: this timestamp is actually a
/// capture timestamp, not a presentation timestamp (it is more of a CTS than a
/// PTS) and is meant to represent the underlying system's best estimate of the
/// capture time of the first frame of audio, including all outboard and hardware
/// introduced buffering delay. As a result, all timestamps produced by an
/// AudioCapturer should be expected to be in the past relative to 'now' on the
/// stream's reference clock timeline.
///
/// The one exception to the "everything has an explicit timestamp" rule is when
/// discarding submitted regions while operating in synchronous mode. Discarded
/// packets have no data in them, but FIDL demands that all pending
/// method-return-value callbacks be executed. Because of this, the regions will
/// be returned to the user, but their timestamps will be set to
/// `NO_TIMESTAMP`, and their payload sizes will be set to zero. Any
/// partially filled payload will have a valid timestamp, but a payload size
/// smaller than originally requested. The final discarded payload (if there
/// were any to discard) will be followed by an OnEndOfStream event.
///
/// Two StreamPackets delivered by an AudioCapturer instance are 'continuous' if
/// the first frame of audio contained in the second packet was captured exactly
/// one nominal frame time after the final frame of audio in the first packet.
/// If this relationship does not hold, the second StreamPacket will have the
/// `STREAM_PACKET_FLAG_DISCONTINUITY` bit set in its `flags` field.
///
/// Even though explicit timestamps are provided on every StreamPacket produced,
/// users who have very precise timing requirements are encouraged to always
/// reason about time by counting frames delivered since the last discontinuity,
/// rather than simply using the raw capture timestamps. This is because the
/// explicit timestamps written on continuous packets may have a small amount of
/// rounding error based on whether or not the units of the capture timeline
/// reference clock are divisible by the chosen audio frame rate.
///
/// Users should always expect the first StreamPacket produced by an
/// AudioCapturer to have the discontinuous flag set on it (as there is no
/// previous packet to be continuous with). Similarly, the first StreamPacket
/// after a DiscardAllPackets or a Stop/Start cycle will always be
/// discontinuous. After that, there are only two reasons that a StreamPacket
/// will ever be discontinuous:
///
/// 1. The user is operating in synchronous mode and does not supply regions to
///    be filled quickly enough. If the next continuous frame of data has not
///    been captured by the time it needs to be purged from the source buffers,
///    an overflow has occurred and the AudioCapturer will flag the next captured
///    region as discontinuous.
/// 2. The user is operating in asynchronous mode and some internal error
///    prevents the AudioCapturer instance from capturing the next frame of audio
///    in a continuous fashion. This might be high system load or a hardware
///    error, but in general it is something which should never normally happen.
///    In practice, however, if it does, the next produced packet will be flagged
///    as being discontinuous.
///
/// **Synchronous vs. Asynchronous Trade-offs**
///
/// The choice of operating in synchronous vs. asynchronous mode is up to the
/// user, and depending on the user's requirements, there are some advantages and
/// disadvantages to each choice.
///
/// Synchronous mode requires only a single Zircon channel under the hood and can
/// achieve some small savings because of this. In addition, the user has
/// complete control over the buffer management. Users specify exactly where
/// audio will be captured to and in what order. Because of this, if users do
/// not need to always be capturing, it is simple to stop and restart the capture
/// later (just by ceasing to supply packets, then resuming later on). Payloads
/// do not need to be uniform in size either, clients may specify payloads of
/// whatever granularity is appropriate.
///
/// The primary downside of operating in synchronous mode is that two messages
/// will need to be sent for every packet to be captured. One to inform the
/// AudioCapturer of the instance to capture into, and one to inform the user
/// that the packet has been captured. This may end up increasing overhead and
/// potentially complicating client designs.
///
/// Asynchronous mode has the advantage requiring only 1/2 of the messages,
/// however, when operating in 'async' mode, AudioCapturer instances have no way
/// of knowing if a user is processing the StreamPackets being sent in a timely
/// fashion, and no way of automatically detecting an overflow condition. Users
/// of 'async' mode should be careful to use a buffer large enough to ensure that
/// they will be able to process their data before an AudioCapturer will be
/// forced to overwrite it.

    /// (henceforth, CT) for the stream to be equal to 1/2 of the time taken by
    /// the number of frames contained within a single tick of the media clock,
    /// rounded up. In this scenario, that would be 24.0 frames of audio, or 500
    /// uSec. Any packets whose expected PTS was within +/-CT frames of the
    /// explicitly provided PTS would be considered to be a continuation of the
    /// previous frame of audio. For this example, calling 'SetPtsContinuityThreshold(0.0005)'
    /// would work well.
    ///
    /// Other possible uses:
    /// Users who are scheduling audio explicitly, relative to a clock which has
    /// not been configured as the reference clock, can use this value to control
    /// the maximum acceptable synchronization error before a discontinuity is
    /// introduced. E.g., if a user is scheduling audio based on a recovered
    /// common media clock, and has not published that clock as the reference
    /// clock, and they set the CT to 20mSec, then up to 20mSec of drift error
    /// can accumulate before the AudioRenderer deliberately inserts a
    /// presentation discontinuity to account for the error.
    ///
    /// Users whose need to deal with a container where their timestamps may be
    /// even less correct than +/- 1/2 of a PTS tick may set this value to
    /// something larger. This should be the maximum level of inaccuracy present
    /// in the container timestamps, if known. Failing that, it could be set to
    /// the maximum tolerable level of drift error before absolute timestamps are
    /// explicitly obeyed. Finally, a user could set this number to a very large
    /// value (86400.0 seconds, for example) to effectively cause *all*
    /// timestamps to be ignored after the first, thus treating all audio as
    /// continuous with previously delivered packets. Conversely, users who wish
    /// to *always* explicitly schedule their audio packets exactly may specify
    /// a CT of 0.
    ///
    /// Note: explicitly specifying high-frequency PTS units reduces the default

    /// have not been discarded since being paused, then the AudioRenderer will
    /// use a media_time corresponding to the instant at which the presentation

    /// (henceforth, CT) for the stream to be equal to 1/2 of the time taken by
    /// the number of frames contained within a single tick of the media clock,

    /// uSec. Any packets whose expected PTS was within +/-CT frames of the
    /// explicitly provided PTS would be considered to be a continuation of the
    /// previous frame of audio. For this example, calling 'SetPtsContinuityThreshold(0.0005)'
    /// would work well.
    ///
    /// Other possible uses:
    /// Users who are scheduling audio explicitly, relative to a clock which has
    /// not been configured as the reference clock, can use this value to control
    /// the maximum acceptable synchronization error before a discontinuity is
    /// introduced. E.g., if a user is scheduling audio based on a recovered
    /// common media clock, and has not published that clock as the reference
    /// clock, and they set the CT to 20mSec, then up to 20mSec of drift error
    /// can accumulate before the AudioRenderer deliberately inserts a
    /// presentation discontinuity to account for the error.
    ///
    /// Users whose need to deal with a container where their timestamps may be
    /// even less correct than +/- 1/2 of a PTS tick may set this value to
    /// something larger. This should be the maximum level of inaccuracy present
    /// in the container timestamps, if known. Failing that, it could be set to
    /// the maximum tolerable level of drift error before absolute timestamps are
    /// explicitly obeyed. Finally, a user could set this number to a very large

    /// timestamps to be ignored after the first, thus treating all audio as

    /// least 75 mSec of lead time, the AudioRenderer might (if 'reference_time'
    /// is omitted) select a reference time 80 mSec from now.
    ///
    /// Media Time
    /// If media_time is omitted, the AudioRenderer will select one of two
    /// values.
    /// - If the AudioRenderer is resuming from the paused state, and packets
    /// have not been discarded since being paused, then the AudioRenderer will
    /// use a media_time corresponding to the instant at which the presentation
    /// became paused.
    /// - If the AudioRenderer is being placed into a playing state for the first
    /// time following startup or a 'discard packets' operation, the initial
    /// media_time will be set to the PTS of the first payload in the pending
    /// packet queue. If the pending queue is empty, initial media_time will be

    /// 1. A user has queued some audio using `SendPacket` and simply wishes them

    /// [ 0, 10, 20, 29, 39, 49, 59, 69, 78, 88, ... ]

    /// into alignment (the 24th packet would start with the 11280th audio frame
    /// and have a PTS of exactly 235).
    ///
    /// One way to fix this situation is to set the PTS continuity threshold
    /// (henceforth, CT) for the stream to be equal to 1/2 of the time taken by
    /// the number of frames contained within a single tick of the media clock,
    /// rounded up. In this scenario, that would be 24.0 frames of audio, or 500
    /// uSec. Any packets whose expected PTS was within +/-CT frames of the
    /// explicitly provided PTS would be considered to be a continuation of the
    /// previous frame of audio. For this example, calling 'SetPtsContinuityThreshold(0.0005)'
    /// would work well.
    ///
    /// Other possible uses:
    /// Users who are scheduling audio explicitly, relative to a clock which has
    /// not been configured as the reference clock, can use this value to control
    /// the maximum acceptable synchronization error before a discontinuity is
    /// introduced. E.g., if a user is scheduling audio based on a recovered
    /// common media clock, and has not published that clock as the reference
    /// clock, and they set the CT to 20mSec, then up to 20mSec of drift error
    /// can accumulate before the AudioRenderer deliberately inserts a
    /// presentation discontinuity to account for the error.
    ///
    /// Users whose need to deal with a container where their timestamps may be
    /// even less correct than +/- 1/2 of a PTS tick may set this value to
    /// something larger. This should be the maximum level of inaccuracy present
    /// in the container timestamps, if known. Failing that, it could be set to
    /// the maximum tolerable level of drift error before absolute timestamps are
    /// explicitly obeyed. Finally, a user could set this number to a very large
    /// value (86400.0 seconds, for example) to effectively cause *all*
    /// timestamps to be ignored after the first, thus treating all audio as
    /// continuous with previously delivered packets. Conversely, users who wish
    /// to *always* explicitly schedule their audio packets exactly may specify
    /// a CT of 0.

    /// requiring at least 3 mSec of lead time, and an HDMI output requiring at
    /// least 75 mSec of lead time, the AudioRenderer might (if 'reference_time'
    /// is omitted) select a reference time 80 mSec from now.
    ///
    /// Media Time
    /// If media_time is omitted, the AudioRenderer will select one of two
    /// values.
    /// - If the AudioRenderer is resuming from the paused state, and packets
    /// have not been discarded since being paused, then the AudioRenderer will
    /// use a media_time corresponding to the instant at which the presentation
    /// became paused.
    /// - If the AudioRenderer is being placed into a playing state for the first
    /// time following startup or a 'discard packets' operation, the initial
    /// media_time will be set to the PTS of the first payload in the pending
    /// packet queue. If the pending queue is empty, initial media_time will be
    /// set to zero.

/// Overview of operation:
///
/// 1. Create
///   * create via CodecFactory - see CodecFactory
///   * create via LicenseSession - see LicenseSession
/// 2. Get input constraints
///   * OnInputConstraints() - sent unsolicited by stream processor shortly
///     after stream processor creation.
/// 3. Provide input buffers ()
///   * SetInputBufferPartialSettings()
///   * or AddBuffer, if StreamProcessor reported support for dynamic buffers
///     via CodecFactory - in this case, QueueInputFormatDetails and
///     QueueInputEndOfStream do not require a prior AddBuffer, but
///     QueueInputPacket still does.
/// 4. Deliver input data
///   * QueueInputPacket() + OnFreeInputPacket(), for as long as it takes,
///     possibly working through all input packets repeatedly before...
/// 5. Get output constraints and format
///   * OnOutputConstraints()
///   * This is not sent until after at least one QueueInput* message is sent by
///     the client, even if the underlying processor behind the StreamProcessor
///     doesn't fundamentally need any input data to determine its output
///     constraints.  This server behavior prevents clients taking an incorrect
///     dependency on the output constraints showing up before input is
///     delivered.
///   * A client must tolerate this arriving as late as after substantial input
///     data has been delivered, including lots of input packet recycling via
///     OnFreeInputPacket().
///   * This message can arrive more than once before the first output data.
/// 6. Provide output buffers
///   * SetOutputBufferPartialSettings() / CompleteOutputBufferPartialSettings()
/// 7. Data flows, with optional EndOfStream
///   * OnOutputPacket() / RecycleOutputPacket() / QueueInputPacket() /
///     OnFreeInputPacket() / QueueInputEndOfStream() / OnOutputEndOfStream()
///
/// Semi-trusted StreamProcessor server - SW decoders run in an isolate (with
/// very few capabilities) just in case the decoding SW has a vulnerability
/// which could be used to take over the StreamProcessor server.  Clients of the
/// stream processor interface using decoders and processing streams of separate
/// security contexts, to a greater extent than some other interfaces, need to
/// protect themselves against invalid server behavior, such as double-free of a
/// packet_index and any other invalid server behavior.  Having fed in
/// compressed data of one security context, don't place too much trust in a
/// single StreamProcessor instance to not mix data among any buffers that
/// StreamProcessor server has ever been told about.  Instead, create separate
/// StreamProcessor instances for use by security-separate client-side contexts.
/// While the picture for HW-based decoders looks somewhat different and is out
/// of scope of this paragraph, the client should always use separate
/// StreamProcessor instances for security-separate client-side contexts.
///
/// Descriptions of actions taken by methods of this protocol and the states of
/// things are given as if the methods are synchronously executed by the stream
/// processor server, but in reality, as is typical of FIDL interfaces, the
/// message processing is async.  The states described are to be read as the
/// state from the client's point of view unless otherwise stated.  Events
/// coming back from the server are of course delivered async, and a client that
/// processes more than one stream per StreamProcessor instance needs to care
/// whether a given event is from the current stream vs. some older
/// soon-to-be-gone stream.
///
/// The Sync() method's main purpose is to enable the client to robustly prevent
/// having both old and new buffers allocated in the system at the same time,

    /// When not using dynamic buffers, upon receiving this message, the server

    /// For video decoders, when using dynamic buffers, typically the client
