[−][src]Struct rusty_ffmpeg::AVPixFmtDescriptor
Descriptor that unambiguously describes how the bits of a pixel are stored in the up to 4 data planes of an image. It also stores the subsampling factors and number of components.
@note This is separate of the colorspace (RGB, YCbCr, YPbPr, JPEG-style YUV and all the YUV variants) AVPixFmtDescriptor just stores how values are stored not what these values represent.
Fields
name: *const c_char
nb_components: u8
< The number of components each pixel has, (1-4)
log2_chroma_w: u8
Amount to shift the luma width right to find the chroma width. For YV12 this is 1 for example. chroma_width = AV_CEIL_RSHIFT(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: u8
Amount to shift the luma height right to find the chroma height. For YV12 this is 1 for example. chroma_height= AV_CEIL_RSHIFT(luma_height, log2_chroma_h) The note above is needed to ensure rounding up. This value only refers to the chroma components.
flags: u64
Combination of AV_PIX_FMT_FLAG_... flags.
comp: [AVComponentDescriptor; 4]
Parameters that describe how pixels are packed. If the format has 1 or 2 components, then luma is 0. If the format has 3 or 4 components: if the RGB flag is set then 0 is red, 1 is green and 2 is blue; otherwise 0 is luma, 1 is chroma-U and 2 is chroma-V.
If present, the Alpha channel is always the last component.
alias: *const c_char
Alternative comma-separated names.
