Field Detail

name

public String name

nb_components

public int nb_components

log2_chroma_w

public int log2_chroma_w

Amount to shift the luma width right to find the chroma width. For YV12 this is 1 for example. chroma_width = -((-luma_width) >> log2_chroma_w) The note above is needed to ensure rounding up. This value only refers to the chroma components.

log2_chroma_h

public int log2_chroma_h

Amount to shift the luma height right to find the chroma height. For YV12 this is 1 for example. chroma_height= -((-luma_height) >> log2_chroma_h) The note above is needed to ensure rounding up. This value only refers to the chroma components.

flags

public int flags

comp

public AVComponentDescriptor[] comp

Parameters that describe how pixels are packed. If the format has chroma components, they must be stored in comp[1] and comp[2].
