57	Excessive memory allocation	fbossen		"Memory allocation is excessive, possibly leading to crashes.

Memory usage has been analyzed for the following case:
class B encoding with max CU=32x32, memory snapshot during encoding of 2nd frame

- Transform coefficients:
9 TComList objects
2040 CUs per frame
3 32x32 integer arrays per CU (luma+2*chroma), each array is 4KB
9 * 2040 * 3 * 32 * 32 * 4 = 215MB
- Luma frame buffers: 40 * 4.48MB = 179MB
- Chroma frame buffers: 79 * 1.12MB = 89MB
- Bitstream buffers (TComBitStream objects): 8 * 11.87MB = 95MB
