Member Function Documentation

nextPtsTicks()

uint64_t nextPtsTicks ( )

inline

Returns the next sample's scheduled presentation time (in this track's timescale ticks, i.e. relative to the track's own start) and advances the internal cursor - call exactly once per dispatched sample, in order. Returns 0 (no pacing) if 'stts' wasn't parsed.

sampleCount()

uint32_t sampleCount ( )

inline

sampleSize()

uint32_t sampleSize ( uint32_t  idx )

inline
