Author: Martin Storsjö <[email protected]> Committer: Martin Storsjö <[email protected]> Date: Mon Jul 15 11:28:46 2013 +0300 ac3dec: Don't consume more data than the actual input packet size This was handled properly in the normal return case at the end of the function, but not in this special case. Returning a value larger than the input packet size can cause problems for certain library users. Returning the actual input buffer size unconditionally, since it is not guaranteed that frame_size is set to a sensible value at this point.
