The problem happens since dcadec was moved to planar formats. The {{{dca_filter_channels}}} lines are debug I added, and they show the problem: the {{{channel_order_tab}}} array, a pointer to {{{dca_channel_reorder_lfe[9]}}} actually, only takes the code 5 channels into account, while the file actually has 7 channels.",defect,closed,important,avcodec,git-master,fixed,dca regression crash SIGSEGV,,,,1,0
