Detailed Description

id RoQ encoder by Vitor.

Based on the Switchblade3 library and the Switchblade3 FFmpeg glue by Eric Lasota.

Macro Definition Documentation

§ EVAL_MOTION

#define EVAL_MOTION ( MOTION )

Value:

do { \
        diff = eval_motion_dist(enc, j, i, MOTION, blocksize); \
            \
        if (diff < lowestdiff) { \
            lowestdiff = diff; \
            bestpick = MOTION; \
        } \
    } while(0)

§ MAX_CBS_4x4

#define MAX_CBS_4x4 256

Maximum number of generated 4x4 codebooks.

Can't be 256 to workaround a Quake 3 bug.
