| int64_t av_i2int | ( | AVInteger | a | ) | const |
Convert the given AVInteger to an int64_t.
If the AVInteger is too large to fit into an int64_t, then only the least significant 64 bits will be used.

| AVInteger av_int2i | ( | int64_t | a | ) |
Convert the given int64_t to an AVInteger.
Definition at line 139 of file integer.c.
Referenced by av_rescale_rnd().
Return the rounded-down value of the base 2 logarithm of the given AVInteger.
This is simply the index of the most significant bit which is 1, or 0 if all bits are 0.
