Types

type CaptureDevice

type CaptureDevice struct {
	Device
	// contains filtered or unexported fields
}

func CaptureOpenDevice

func CaptureOpenDevice(name string, freq uint32, format uint32, size uint32) *CaptureDevice

func (*CaptureDevice) CaptureCloseDevice

func (self *CaptureDevice) CaptureCloseDevice() bool

func (*CaptureDevice) CaptureSamples

func (self *CaptureDevice) CaptureSamples(size uint32) (data []byte)

func (*CaptureDevice) CaptureStart

func (self *CaptureDevice) CaptureStart()

func (*CaptureDevice) CaptureStop

func (self *CaptureDevice) CaptureStop()

func (*CaptureDevice) CloseDevice

func (self *CaptureDevice) CloseDevice() bool

XXX: Override Device.CloseDevice to make sure the correct C function is called even if someone decides to use this behind an interface.

type Context

type Context struct {
	// contains filtered or unexported fields
}

Context encapsulates the state of a given instance of the OpenAL state machine. Only one context can be active in a given process.

var NullContext Context

A context that doesn't exist, useful for certain context operations (see OpenAL documentation for details).

func CurrentContext

func CurrentContext() *Context

Renamed, was GetCurrentContext.

func (*Context) Activate

func (self *Context) Activate() bool

Renamed, was MakeContextCurrent.

func (*Context) Destroy

func (self *Context) Destroy()

Renamed, was DestroyContext.

func (*Context) GetDevice

func (self *Context) GetDevice() *Device

Renamed, was GetContextsDevice.

func (*Context) Process

func (self *Context) Process()

Renamed, was ProcessContext.

func (*Context) Suspend

func (self *Context) Suspend()

Renamed, was SuspendContext.

type Device

type Device struct {
	// contains filtered or unexported fields
}

func OpenDevice

func OpenDevice(name string) *Device

func (*Device) CloseDevice

func (self *Device) CloseDevice() bool

func (*Device) CreateContext

func (self *Device) CreateContext() *Context

func (*Device) GetError

func (self *Device) GetError() uint32

GetError() returns the most recent error generated in the AL state machine.

func (*Device) GetInteger

func (self *Device) GetInteger(param uint32) int32

func (*Device) GetIntegerv

func (self *Device) GetIntegerv(param uint32, size uint32) (result []int32)

type Recorder

type Recorder struct {
	// contains filtered or unexported fields
}

func Open

func Open(gco *coroutine.Coroutines) *Recorder

func (*Recorder) Close
