vlc_tick_t input_GetItemDuration | ( | input_thread_t * | input, |

Calculates the duration of the item in an input thread.
This function determines the duration of a track item based on the start and stop times stored in the input thread's private data. If the stop time is not set (i.e., equals zero), the function considers the given duration
as the stop time and calculates the effective duration based on the start time. Otherwise, it calculates the duration using the set start and stop times.
input | Pointer to the input_thread_t object. |
duration | The initial duration value, used if the stop time is not set. |
