◆ init()

std::pair< QShader, QShader > score::gfx::HAPMDecoder::init ( RenderList r)
overridevirtual

Initialize a GPUVideoDecoder.

This method must :

  • Create samplers and textures for the video format.
  • Create shaders that will render the data put into these textures.

It returns a {vertex, fragment} shader pair.

Implements score::gfx::GPUVideoDecoder.
