Detailed Description

Theora bitstream info.

Contains the basic playback parameters for a stream, corresponding to the initial 'info' header packet.

Encoded theora frames must be a multiple of 16 in width and height. To handle other frame sizes, a crop rectangle is specified in frame_height and frame_width, offset_x and * offset_y. The offset and size should still be a multiple of 2 to avoid chroma sampling shifts. Offset values in this structure are measured from the upper left of the image.

Frame rate, in frames per second, is stored as a rational fraction. Aspect ratio is also stored as a rational fraction, and refers to the aspect ratio of the frame pixels, not of the overall frame itself.

See examples/encoder_example.c for usage examples of the other paramters and good default settings for the encoder parameters.
