HOW TO USE

Allows compile-time extension of types without directly modifying them across modules.

1) Like any static function, declare (by specialization) the extension in a header:

template <> FAVResult FAVExtension::TransformConfig(FVideoConfigH264& OutConfig, FVideoConfigBitstream const& InConfig);

2) Then define the extension in the source:

template <> DLLEXPORT FAVResult FAVExtension::TransformConfig(FVideoConfigH264& OutConfig, FVideoConfigBitstream const& InConfig) { // do stuff }

Be sure to EXPORT the definition and it will be automatically linked by consumers. Static extension system for simple composition of different resource/config types, via exported specializations

IsCompatible ( TSharedPtr< class FAVDevice > const& Device
)

 Check if a type is compatible in a certain context, with a certain device.

TransformResource ( TSharedPtr< FVideoResourceRHI >& OutResource,
TSharedPtr< class FVideoResourceRHI > const& InResource
)

 Handles pixel format or colorspace transformations
Public function Static FAVResult

TransformResource ( TSharedPtr< TOutput >& OutResource,
TSharedPtr< TInput > const& InResource
)

 Transform one resource type into another.
Public function Static FAVResult

TransformResource ( TSharedPtr< TOutput >& OutResource,
TSharedPtr< TInput > const& InResource
)

 Shortcut case for above for when the input and output types match. This does NOT duplicate the resource.
Public function FAVResult

TransformResource ( TSharedPtr< FVideoResourceRHI >& OutResource,
TSharedPtr< FVideoResourceCPU > const& InResource
)

Classes

  Type Name Description
Public struct TIsSameHack Versions of TAnd and TOr that work with std::is_same return values, this is incompatible with TEMPLATE_REQUIRES so we need to still use this construct for now until std::is_same_v is better supported
