int64_t av_rescale_rnd(int64_t a, int64_t b, int64_t c, enum AVRounding rnd)
Rescale a 64-bit integer with specified rounding.
#define av_assert0(cond)
assert() equivalent, that is always enabled.
#define av_assert2(cond)
assert() equivalent, that does lie in speed critical code.
AVRational av_mul_q(AVRational b, AVRational c)
Multiply two rationals.
int64_t av_i2int(AVInteger a)
Convert the given AVInteger to an int64_t.
int64_t av_rescale_q(int64_t a, AVRational bq, AVRational cq)
Rescale a 64-bit integer by 2 rational numbers.
AVInteger av_int2i(int64_t a)
Convert the given int64_t to an AVInteger.
const uint8_t av_reverse[256]
Reverse the order of the bits of an 8-bits unsigned integer.
Round to nearest and halfway cases away from zero.
AVInteger av_mul_i(AVInteger a, AVInteger b)
simple assert() macros that are a bit more flexible than ISO C assert().
int64_t av_gcd(int64_t a, int64_t b)
Return the greatest common divisor of a and b.
Libavutil version macros.
int av_compare_ts(int64_t ts_a, AVRational tb_a, int64_t ts_b, AVRational tb_b)
Compare 2 timestamps each in its own timebases.

Rescale a timestamp while preserving known durations.
rational number numerator/denominator
common internal and external API header
int64_t av_add_stable(AVRational ts_tb, int64_t ts, AVRational inc_tb, int64_t inc)

Flag to pass INT64_MIN/MAX through instead of rescaling, this avoids special cases for AV_NOPTS_VALUE...
#define AV_NOPTS_VALUE
Undefined timestamp value.
int64_t av_compare_mod(uint64_t a, uint64_t b, uint64_t mod)
Compare 2 integers modulo mod.
