From a246d06fe0dc6c2ea65e95327624b4537ff9bd0d Mon Sep 17 00:00:00 2001 From: Guillaume Martres Date: Sat, 11 Jan 2014 22:46:24 +0100 Subject: hevc: clip pixels when transquant bypass is used The reconstructed picture should always be clipped (see section 8.6.5), previously we did not clip coding units where cu_transquant_bypass_flag == 1.
