From 696b446f097a3a00e19307a1106c950a170b80a1 Mon Sep 17 00:00:00 2001 From: Sreerenj Balachandran Date: Thu, 6 Aug 2015 04:01:24 +0300 Subject: [PATCH] decoder: hevc: Fix decoding of stream when it has temporal sublayers We are calculating the dpb size based on max_dec_pic_buffering. But if there are more than one temporal sublayers, we are supposed to use the max_dec_pic_buffering[max_sub_layers_minus] for dpb size calculation (Assuming HighestTid as max_sub_layers_minus).
