Constant AV_TX_INT32_DCT

pub const AV_TX_INT32_DCT: u32 = 11; // 11u32

Real to real (DCT) transforms.

The forward transform is a DCT-II. The inverse transform is a DCT-III.

The input array is always overwritten. DCT-III requires that the input be padded with 2 extra samples. Stride must be set to the spacing between two samples in bytes.
