    Prevent encoder crash caused by row tile dependencies · dc5f7712

    In multi-thread case, the encoder may crash if using encoder option
    tile-rows > 0. To prevent that, force tile-rows=0 in this situation.
    This is a workaround for WebM issue 1095:
    The further fix can be done by adding synchronizations after a tile
    row is encoded. But this will hurt multi-threaded encoder performance.
    So, it is recommended to use tile-rows=0 while encoding with threads
    > 1.
