枚举 _bindgen_ty_2 

#[repr(i32)]
pub enum _bindgen_ty_2 {
    AV_HWFRAME_MAP_READ = 1,
    AV_HWFRAME_MAP_WRITE = 2,
    AV_HWFRAME_MAP_OVERWRITE = 4,
    AV_HWFRAME_MAP_DIRECT = 8,
}

Flags to apply to frame mappings.

Variants

AV_HWFRAME_MAP_READ = 1

The mapping must be readable.

AV_HWFRAME_MAP_WRITE = 2

The mapping must be writeable.

AV_HWFRAME_MAP_OVERWRITE = 4

The mapped frame will be overwritten completely in subsequent operations, so the current frame data need not be loaded. Any values which are not overwritten are unspecified.

AV_HWFRAME_MAP_DIRECT = 8

The mapping must be direct. That is, there must not be any copying in the map or unmap steps. Note that performance of direct mappings may be much lower than normal memory.
