枚举 AVSideDataProps 

#[repr(i32)]
pub enum AVSideDataProps {
    AV_SIDE_DATA_PROP_GLOBAL = 1,
    AV_SIDE_DATA_PROP_MULTI = 2,
    AV_SIDE_DATA_PROP_SIZE_DEPENDENT = 4,
    AV_SIDE_DATA_PROP_COLOR_DEPENDENT = 8,
    AV_SIDE_DATA_PROP_CHANNEL_DEPENDENT = 16,
}

Variants

AV_SIDE_DATA_PROP_GLOBAL = 1

The side data type can be used in stream-global structures. Side data types without this property are only meaningful on per-frame basis.

AV_SIDE_DATA_PROP_MULTI = 2

Multiple instances of this side data type can be meaningfully present in a single side data array.

AV_SIDE_DATA_PROP_SIZE_DEPENDENT = 4

Side data depends on the video dimensions. Side data with this property loses its meaning when rescaling or cropping the image, unless either recomputed or adjusted to the new resolution.

AV_SIDE_DATA_PROP_COLOR_DEPENDENT = 8

Side data depends on the video color space. Side data with this property loses its meaning when changing the video color encoding, e.g. by adapting to a different set of primaries or transfer characteristics.

AV_SIDE_DATA_PROP_CHANNEL_DEPENDENT = 16

Side data depends on the channel layout. Side data with this property loses its meaning when downmixing or upmixing, unless either recomputed or adjusted to the new layout.
