From 5b2544f8689706de4cedebbb6777bb375af78325 Mon Sep 17 00:00:00 2001 From: Ruijing Dong Date: Tue, 23 May 2023 09:47:59 -0400 Subject: [PATCH] gallium/pipe: add interface update_decoder_target reason: decoder uses the target buffer address in record to indentify the reference frames. When target buffer has changed outside of decoding process, it has to be updated back to decoder, otherwise the outdated reference will cause image corruption.
