◆ vlc_input_decoder_AddVoutOverlay()

◆ vlc_input_decoder_ChangePause()

void vlc_input_decoder_ChangePause ( vlc_input_decoder_t p_owner,
bool  b_paused,
vlc_tick_t  i_date 

This function changes the pause state.

The date parameter MUST hold the exact date at which the change has been done for proper vout/aout pausing.
