Inheritance diagram for score::gfx::Y210Decoder:

Detailed Description

Decodes Y210 packed 4:2:2 10-bit videos.

Packed as Y0 U Y1 V, each 16-bit with data in the high bits. 8 bytes per macropixel (2 pixels). Uploaded as RGBA16F at {w/2, h}. tex.r=Y0, tex.g=U, tex.b=Y1, tex.a=V.

Data in high bits means R16 unorm already returns [0,1] normalized values.

Member Function Documentation

exec()

void score::gfx::Y210Decoder::exec ( RenderList &  , QRhiResourceUpdateBatch &  res, AVFrame &  frame  )

inlineoverridevirtual

Decode and upload a video frame to the GPU.

Implements score::gfx::GPUVideoDecoder.

init()

std::pair< QShader, QShader > score::gfx::Y210Decoder::init ( RenderList &  r )

inlineoverridevirtual

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.
