GlEffect

GlEffect

Interface for a video frame effect with a GlShaderProgram implementation.

Known indirect subclasses

`AlphaScale`	Scales the alpha value (i.e. the translucency) of a frame.
`Brightness`	Modifies brightness of an input frame.
`ByteBufferGlEffect`	A `GlEffect` implementation that runs an asynchronous `Processor` on video frame data passed in as a `ByteBufferGlEffect.Image`.
`ColorLut`	Specifies color transformations using color lookup tables to apply to each frame in the fragment shader.
`Contrast`	A `RgbMatrix` to control the contrast of video frames.
`Crop`	Specifies a crop to apply in the vertex shader.
`FrameCache`	Caches the input frames.
`FrameDropEffect`	Drops frames to lower average frame rate to around `targetFrameRate`.
`GaussianBlurWithFrameOverlaid`	A `SeparableConvolution` to apply a Gaussian blur on image data.
`GaussianBlur`	A `SeparableConvolution` to apply a Gaussian blur on image data.
`GlMatrixTransformation`	Specifies a 4x4 transformation `Matrix` to apply in the vertex shader for each input frame.
`HslAdjustment`	Adjusts the HSL (Hue, Saturation, and Lightness) of a frame.
`LanczosResample`	A `GlEffect` that applies a Lanczos-windowed sinc function when resampling an image.
`MatrixTransformation`	Specifies a 3x3 transformation `Matrix` to apply in the vertex shader for each frame.
`OverlayEffect`	Applies a list of `TextureOverlay`s to a frame in FIFO order (the last overlay in the list is displayed on top).
`Presentation`	Controls how a frame is presented with options to set the output resolution and choose how to map the input pixels onto the output frame geometry (for example, by stretching the input frame to match the specified output frame, or fitting the input frame using letterboxing).
`RgbAdjustment`	Scales the red, green, and blue color channels of a frame.
`RgbFilter`	Provides common color filters.
`RgbMatrix`	Specifies a 4x4 RGB color transformation matrix to apply to each frame in the fragment shader.
`ScaleAndRotateTransformation`	Specifies a simple rotation and/or scale to apply in the vertex shader.
`SeparableConvolution`	A `GlEffect` for performing separable convolutions.
`SingleColorLut`	Transforms the colors of a frame by applying the same color lookup table to each frame.
`SpeedChangeEffect`	Applies a speed change by updating the frame timestamps.
`TimestampAdjustment`	Changes the frame timestamps using the `TimestampMap`.
`TimestampWrapper`	Applies a `GlEffect` from `startTimeUs` to `endTimeUs`, and no change on all other timestamps.

Marker interface for a video frame effect.

Summary

Public methods
`default long`	`getDurationAfterEffectApplied(long durationUs)` Returns the expected duration of the output stream when the effect is applied given a input `durationUs`.
