Author: Martin Storsjö <[email protected]> Committer: Martin Storsjö <[email protected]> Date: Fri Mar 1 16:45:24 2013 +0200 flvdec: Check the return value of a malloc The callers of this function can't report errors sanely. If this one malloc fails, don't write the extradata byte, make sure we try to malloc it the next time we're called instead, and make sure we still consume the input data byte.
