Author: Andreas Cadhalpun <[email protected]> Committer: Luca Barbato <[email protected]> Date: Fri Jul 10 21:59:32 2015 +0200 imc: Use correct position for flcoeffs2 calculation flcoeffs2[pos] should be the log2 of flcoeffs1[pos]. flcoeffs1[0] can be 0 here, thus flcoeffs2[pos] gets set to -inf, causing problems further down. This seems to have been copied from imc_decode_level_coefficients in commit 4eb4bb3 without updating the position.
