Detailed Description

D3DFMT_X8R8G8B8 and RGB24 renderer.

Supporting WMV and any video format codec available in the system.

Member Function Documentation

§ CreateTexture()

HRESULT CTextureRenderer::CreateTexture ( LPDIRECT3DTEXTURE9 *  pTexture)

this function will return when the video is initialized and its size is known.

Internally it will wait for the codec to be ready.

Note
: there is a timeout of 100 milliseconds, if the codec still has no idea of the media type, it will return E_UNEXPECTED.

§ DoRenderSample()

HRESULT CTextureRenderer::DoRenderSample ( IMediaSample *  pMediaSample)
virtual

this is most important function.

this function is called in the codec thread.

Called when a new sample has been rendered. we just keep it in a temporary buffer.

Reimplemented from CBaseRenderer.

§ GetHeight()

int CTextureRenderer::GetHeight ( )

this function will return when the video is initialized and its size is known.

Internally it will wait for the codec to be ready.

Note
: there is a timeout of 100 milliseconds, if the codec still has no idea of the media type, it will return 0.

§ GetWidth()

int CTextureRenderer::GetWidth ( )

this function will return when the video is initialized and its size is known.

Internally it will wait for the codec to be ready.

Note
: there is a timeout of 100 milliseconds, if the codec still has no idea of the media type, it will return 0.

§ lock()

HRESULT CTextureRenderer::lock ( byte **  data,
int *  nSize 
)

one can retrieve texture data by lock this.

No longer to use this function if one uses UpdateTexture() to retrieve data directly into a d3d texture created by CreateTexture().

§ UpdateTexture()

HRESULT CTextureRenderer::UpdateTexture ( LPDIRECT3DTEXTURE9  pTexture)

update the texture with the latest content.

It is safe to call this function at higher frequency than the movie frame rate. it will internally detect if the current frame has changed since the last invocation of this function.
