QFFmpeg::TextureConverterBackend Class Reference

The base class for platform-specific implementations of TextureConverter One of two virtual methods, createTextures and createTextureHandles, must be overridden. If the implementation operates with QRhiTexture under the hood, overriding of createTextures is prefferable, otherwise expose texture handles of native textures by createTextureHandles. More...

	Points to the matching QRhi. If the constructor, createTextures, or createTextureHandles get failed without chances for recovery, it may set the pointer to nullptr, which will invalidate the parent TextureConverter, and textures creation won't be invoked anymore.

Detailed Description

The base class for platform-specific implementations of TextureConverter One of two virtual methods, createTextures and createTextureHandles, must be overridden. If the implementation operates with QRhiTexture under the hood, overriding of createTextures is prefferable, otherwise expose texture handles of native textures by createTextureHandles.
