From b41e4f6187a10e729288fcf9ff5584f47a6a34e9 Mon Sep 17 00:00:00 2001 From: Andreas Rheinhardt Date: Tue, 9 Mar 2021 20:25:06 +0100 Subject: [PATCH] avcodec/h264_cavlc: Remove redundant check The only caller to ff_h264_decode_init_vlc() already uses ff_thread_once() for the call; ergo the check via a simple int with static storage duration in ff_h264_decode_init_vlc() is redundant. And if it were not redundant, it would be a potential for data races. So remove it.
