Direct Known Subclasses:

RV32BufferFormat

public class BufferFormat
extends Object

Specifies the formats used by the CallbackVideoSurface.

The buffer will contain data of the given width and height in the format specified by the chroma parameter. A buffer can consist of multiple planes depending on the format of the data. For each plane the pitch and height in lines must be supplied.

For example, RV32 format has only one plane. Its pitch is width * 4, and its number of lines is the same as the height.

Constructor Detail

BufferFormat

public BufferFormat(String chroma,
                    int width,
                    int height,
                    int[] pitches,
                    int[] lines)

Constructs a new BufferFormat instance with the given parameters.

Parameters:

chroma - a VLC buffer type, must be exactly 4 characters and cannot contain non-ASCII characters

width - the width, must be > 0

height - the height, must be > 0

pitches - the pitch of each plane that this buffer consists of (usually a multiple of width)

lines - the number of lines of each plane that this buffer consists of (usually same as height)

Throws:

IllegalArgumentException - if any parameter is invalid
