mxfdec: fix Avid AirSpeed files being misinterpreted as OP1a
The "ECs != 1 -> OP1a" assumption was wrong. Luckily, the file that triggered that behavior had two ECs, not zero. Hence distinguishing between them is simple in this case. Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
