From 05d1e45d1f42cc90d1f2f36c546d0096cea126a8 Mon Sep 17 00:00:00 2001 From: Justin Ruggles Date: Tue, 22 Nov 2011 13:37:52 -0500 Subject: wma: initialize prev_block_len_bits, next_block_len_bits, and block_len_bits. The initial values are not checked against the number of block sizes. Initializing them to frame_len_bits will result in a block size index of 0 in these cases instead of something that might be out-of-range.
