From 4834f01bdf9b9f371fcbb0b9cf4f7297fdf1fd55 Mon Sep 17 00:00:00 2001 From: Jean-Michel Trivi Date: Tue, 5 Apr 2016 12:38:32 -0700 Subject: Fix aacDecoder_drcExtractAndMap() Parse DVB DRC data only when numThreads is below MAX_DRC_THREADS. The post-increment is necessary as it is used in fill element DRC data section. This solution parses as many DRC payloads as allowed by MAX_DRC_THREADS and skips all remaining DRC elements in the stream.
