Message-ID: <TYSPR06MB64330E2CD616C967A8D39715AA562@TYSPR06MB6433.apcprd06.prod.outlook.com> (raw)
In-Reply-To: <20240222071406.5714-1-nuomi2021@gmail.com>

Intra Block Copy relies on reconstructed pixels from the current frame.
We skip IBC during the inter prediction stage and handle it during the reconstruction stage.
