class SimpleCodecServer

Defined at line 31 of file ../../src/media/audio/lib/simple-codec/include/lib/simple-codec/simple-codec-server.h

This class provides an implementation of the audio codec protocol to be subclassed by codec

drivers. The subclass must implement all the virtual methods and use Create() for construction.

Public Methods

template <typename T, typename... ConstructorSignature>

zx_status_t CreateAndAddToDdk (ConstructorSignature &&... args)

Create

A general method which handles the construction/initialization of

SimpleCodecServer implementation. Given an implementation called

'MyCodec', invocation should look something like..

auto codec = SimpleCodecServer::Create

<MyCodec

>(arg1, arg2, ...);

bool SupportsSignalProcessing ()

Default only used for gain, mute and AGC support, override for custom signal processing API

usage.

async_dispatcher_t * dispatcher ()

The dispatcher's loop is guaranteed to be shutdown before "this" is deleted.

zx_status_t CodecConnect (zx::channel channel)

Defined at line 117 of file ../../src/media/audio/lib/simple-codec/simple-codec-server.cc

zx::result<DriverIds> Initialize ()

Called during Create(), it must return DriverIds or an error. Any resources allocated here must

be released before destruction, for instance in the Shutdown hook or the class destructor.

zx_status_t Shutdown ()

Called right before deallocation of the driver in DdkRelease() and also if there is an error

during creation in Create().

zx_status_t Reset ()

Protocol methods to be implemented by the driver, for descriptions see

//docs/concepts/drivers/driver_interfaces/audio_codec.md

Methods are simplified to use standard C++ types (see simple-codec-types.h) and also:

- Only allow standard frame formats (DaiFrameFormatStandard, see

//sdk/fidl/fuchsia.hardware.audio/dai_format.fidl).

- GetDaiFormats returns one DaiSupportedFormats instead of a vector (still allows supported

formats with multiple frame rates, number of channels, etc. just not overly complex ones).

- No need to implement WatchGainState, gain must only be changed by SetGainState.

- No need to implement WatchPlugState, the library always advertises "hardwired".
