◆ ff_timecode_set_smpte()

void ff_timecode_set_smpte ( unsigned * drop,

unsigned * hh,

unsigned * mm,

unsigned * ss,

unsigned * ff,

AVRational rate,

uint32_t tcsmpte,

int prevent_df,

int skip_field

)

Convert SMPTE 12M binary representation to sei info.

Parameters: drop drop flag output

hh hour output

mm minute output

ss second output

ff frame number output

rate frame rate of the timecode

tcsmpte the 32-bit SMPTE timecode

prevent_df prevent the use of a drop flag when it is known the DF bit is arbitrary

skip_field prevent the use of a field flag when it is known the field bit is arbitrary (e.g. because it is used as PC flag)
