From 36e7f9b3395d3be21fb77462f2c620487b92784d Mon Sep 17 00:00:00 2001 From: Andreas Rheinhardt Date: Sun, 24 Sep 2023 15:34:31 +0200 Subject: [PATCH] avcodec/vqcdec: Avoid unnecessary VLC structure Everything besides VLC.table is basically write-only and even VLC.table can be removed by accessing the underlying table directly.
