Member Function Documentation

void TorcPiCamera::BufferReady ( OMX_BUFFERHEADERTYPE *  Buffer, quint64  Type  )

slot

An OpenMax buffer is ready (full)

This method is signalled when a buffer becomes available - for our use case, this is after TorcOMXComponent::FillThisBuffer has completed.

Definition at line 245 of file torcpicamera.cpp.

bool TorcPiCamera::EnableStills ( uint  Count )

overrideprotectedvirtual

Reimplemented from TorcCameraDevice.

Definition at line 916 of file torcpicamera.cpp.

bool TorcPiCamera::Setup ( void  )

overridevirtual

Reimplemented from TorcCameraDevice.

Definition at line 133 of file torcpicamera.cpp.

bool TorcPiCamera::Start ( void  )

overridevirtual

Start the camera.

The camera device is event driven but we must kick off by asking for output buffers to be filled.

Implements TorcCameraDevice.

Definition at line 229 of file torcpicamera.cpp.

void TorcPiCamera::StartStill ( void  )

overrideprotectedvirtual

Start capturing a still image buffer.

Note

This SHOULD be called at the start of stills capture or when the previous still has been completed. In both cases a buffer should be available and this method will then be non-blocking.

Implements TorcCameraDevice.

Definition at line 273 of file torcpicamera.cpp.

bool TorcPiCamera::Stop ( void  )

overridevirtual

Implements TorcCameraDevice.

Definition at line 422 of file torcpicamera.cpp.

void TorcPiCamera::StreamVideo ( bool  Video )
