Possible memory leak when using ACP

[jsauer]

I noticed that simulations which I ran for the ACP format take much more memory than for the other formats. I was using 360Lib-3.0rc1 with HM-16.15. I also did simulations for CMP and ERP. For the same sequence CMP needed 5GB of RAM while ACP needed 12GB. Detailed calls of encoders below.

CMP:

Th bug is fixed under "SVIDEO_FIX_TICKET49", and it is included in 360Lib-3.0.
