From 73b3ea572819a79e7896627e4c1daf74ce1dfe46 Mon Sep 17 00:00:00 2001 From: Andreas Rheinhardt Date: Sun, 1 Nov 2020 02:17:43 +0100 Subject: [PATCH] avcodec/g2meet: Use least max_depth in get_vlc2() The longest AC codes of the standard JPEG tables are 16 bits long; for the DC tables, the maximum is 11, so using max_depth of two is sufficient.
