Primary classes

# ofxOMXVideoGrabber:

Used for video capture and recording. Video is hardware accelerated and written to a texture (texture mode) or directly to the screen. Texture Mode allows:

• Shaders
• Pixel access
• Overlays, etc

# ofxOMXPhotoGrabber

Used for controlling still functionality of the camera. Only hardware accelerated features are enabled (e.g. JPG compression). Similar to video mode, a preview can be rendered to a texture or directly to the screen.

# RECORDING:

Recording is available in both texture and non-texture modes

EXAMPLES:

VIDEO

# example-demo-mode

Shows different settings available to tweak the camera exposure, metering, cropping, zooming, filters, mirroring, white balance

# example-direct-mode

Camera turns on and is rendered full screen via OMX acceleration Press the "e" key to toggle through built in filters

# example-direct-mode-transform

Demos cropping, alpha, mirroring of direct display (not camera)

# example-texture-mode

Camera turns on and renders to a texture that is drawn at full screen and a scaled version Press the "e" key to toggle through built in filters

# example-shaders

Basic shader usage with texture-mode Press the "e" key to toggle through built in filters Press the "s" key to toggle shader

# example-saved-settings:

Alternative way to load a camera configuration through a text file

# example-recording:

Recording of video in texture or direct mode

# example-wrapper:

Drop-in replacement for ofVideoGrabber (texture-mode only)
