GetPasses()

ShaderPassVec & CShaderPresetGL::GetPasses ( )

overridevirtual

Gets the passes of the loaded preset.

Returns

All the video shader passes of the currently loaded preset

Implements KODI::SHADER::IShaderPreset.

GetShaderPreset()

const std::string & CShaderPresetGL::GetShaderPreset ( ) const

overridevirtual

Gets the full path to the shader preset.

Returns

The full path to the currently loaded preset file

Implements KODI::SHADER::IShaderPreset.

ReadPresetFile()

bool CShaderPresetGL::ReadPresetFile ( const std::string &  presetPath )

overridevirtual

Reads/Parses a shader preset file and loads its state to the object. What this state is is implementation specific.

Parameters

presetPath

Full path of the preset file.

Returns

True on successful parsing, false on failed.

Implements KODI::SHADER::IShaderPreset.

RenderUpdate()

bool CShaderPresetGL::RenderUpdate ( const CPoint  dest[], IShaderTexture *  source, IShaderTexture *  target  )

overridevirtual

Updates state if needed and renderes the preset to the target texture.

Parameters

dest	Coordinates of the 4 corners of the output viewport/window
source	Input texture. The source of the video frame, in is original resolution (unscaled)
target	The target texture. The texture that the final result will be rendered in.

Returns

Returns false if updating or rendering failed, true if both succeeded.

Implements KODI::SHADER::IShaderPreset.

SetShaderPreset()

bool CShaderPresetGL::SetShaderPreset ( const std::string &  shaderPresetPath )

overridevirtual

Set the preset to be rendered on the next frame.

Parameters

shaderPresetPath

Full path to the preset file to be loaded

Returns

Returns false if loading the preset failed, true otherwise.

Implements KODI::SHADER::IShaderPreset.

SetSpeed()

void CShaderPresetGL::SetSpeed ( double  speed )

overridevirtual

Informs about the speed of playback.

Parameters

speed

Commonly 1.0 for normal playback, and 0.0 if paused

Implements KODI::SHADER::IShaderPreset.

SetVideoSize()

void CShaderPresetGL::SetVideoSize ( const unsigned  videoWidth, const unsigned  videoHeight  )

overridevirtual

Size of the input/source frame in pixels.

Parameters

videoWidth	Height of the source frame in pixels
videoHeight	Height of the source frame in pixels

Implements KODI::SHADER::IShaderPreset.
