Module: libav Branch: release/0.7 Commit: 8dba5608dcf76032d8a9aa4bd8a3fc1392682281
Author: Justin Ruggles <[email protected]> Committer: Reinhard Tartler <[email protected]> Date: Tue Nov 22 13:37:52 2011 -0500 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. Fixes Bug 81.
