int bslice_16x16_termination_control ( Block8x8Info *  b8x8info,

int CheckReliabilityOfRef ( int  block,
int  list_idx,
int  ref,
int  mode 
)

Checks if a given reference frame is reliable for the current macroblock, given the motion vectors that the motion search has returned.

Returns:
If the return value is 1, the reference frame is reliable. If it is 0, then it is not reliable.
Note:
A specific area in each reference frame is assumed to be unreliable if the same area has been intra-refreshed in a subsequent frame. The information about intra-refreshed areas is kept in the pixel_map.
