Enumeration Type Documentation

◆ AVRounding

enum AVRounding

Enumerator
AV_ROUND_ZERO	Round toward zero.
AV_ROUND_INF	Round away from zero.
AV_ROUND_DOWN	Round toward -infinity.
AV_ROUND_UP	Round toward +infinity.
AV_ROUND_NEAR_INF	Round to nearest and halfway cases away from zero.
AV_ROUND_PASS_MINMAX	Flag telling rescaling functions to pass `INT64_MIN`/`MAX` through unchanged, avoiding special cases for AV_NOPTS_VALUE. Unlike other values of the enumeration AVRounding, this value is a bitmask that must be used in conjunction with another value of the enumeration through a bitwise OR, in order to set behavior for normal cases. av_rescale_rnd(3, 1, 2, AV_ROUND_UP \| AV_ROUND_PASS_MINMAX); // Rescaling 3: // Calculating 3 * 1 / 2 // 3 / 2 is rounded up to 2 // => 2 av_rescale_rnd(AV_NOPTS_VALUE, 1, 2, AV_ROUND_UP \| AV_ROUND_PASS_MINMAX); // Rescaling AV_NOPTS_VALUE: // AV_NOPTS_VALUE == INT64_MIN // AV_NOPTS_VALUE is passed through // => AV_NOPTS_VALUE
