can't find a const val AV_CODEC_CAP_ENCODER_RECON_FRAME

[yollpoll]

here is my code:
`use bitflags::bitflags;
use crate::ffi::*;
use libc::c_uint;

bitflags! {
pub struct Capabilities: c_uint {
const DRAW_HORIZ_BAND = AV_CODEC_CAP_DRAW_HORIZ_BAND;
const DR1 = AV_CODEC_CAP_DR1;
const DELAY = AV_CODEC_CAP_DELAY;
const SMALL_LAST_FRAME = AV_CODEC_CAP_SMALL_LAST_FRAME;
const SUBFRAMES = AV_CODEC_CAP_SUBFRAMES;
const EXPERIMENTAL = AV_CODEC_CAP_EXPERIMENTAL;
const CHANNEL_CONF = AV_CODEC_CAP_CHANNEL_CONF;
const FRAME_THREADS = AV_CODEC_CAP_FRAME_THREADS;
const SLICE_THREADS = AV_CODEC_CAP_SLICE_THREADS;
const PARAM_CHANGE = AV_CODEC_CAP_PARAM_CHANGE;
const OTHER_THREADS = AV_CODEC_CAP_OTHER_THREADS;
const VARIABLE_FRAME_SIZE = AV_CODEC_CAP_VARIABLE_FRAME_SIZE;
const AVOID_PROBING = AV_CODEC_CAP_AVOID_PROBING;
const HARDWARE = AV_CODEC_CAP_HARDWARE;
const HYBRID = AV_CODEC_CAP_HYBRID;
const ENCODER_REORDERED_OPAQUE = AV_CODEC_CAP_ENCODER_REORDERED_OPAQUE;
const ENCODER_FLUSH = AV_CODEC_CAP_ENCODER_FLUSH;
const ENCODER_RECON_FRAME = AV_CODEC_CAP_ENCODER_RECON_FRAME;
}
}`
the 'AV_CODEC_CAP_ENCODER_RECON_FRAME' couldn't been found, is there something wrong in my project or env?
my sys is windows10 and ffmepg libraries's version is 5.1.2 installed by vcpkg
