◆ vlc_player_state

enum vlc_player_state

State of the player.

During a normal playback (no errors), the user is expected to receive all events in the following order: STARTED, PLAYING, STOPPING, STOPPED.

Note: When playing more than one media in a row, the player stay at the PLAYING state when doing the transition from the current media to the next media (that can be gapless). This means that STOPPING, STOPPED states (for the current media) and STARTED, PLAYING states (for the next one) won't be sent. Nevertheless, the vlc_player_cbs.on_current_media_changed callback will be called during this transition.

Enumerator
VLC_PLAYER_STATE_STOPPED	The player is stopped. Initial state, or triggered by an internal transition from the STOPPING state.
VLC_PLAYER_STATE_STARTED	The player is started. Triggered by vlc_player_Start()
VLC_PLAYER_STATE_PLAYING	The player is playing. Triggered by vlc_player_Resume() or by an internal transition from the STARTED state.
VLC_PLAYER_STATE_PAUSED	The player is paused. Triggered by vlc_player_Pause().
VLC_PLAYER_STATE_STOPPING	The player is stopping. Triggered by vlc_player_Stop(), vlc_player_SetCurrentMedia() or by an internal transition (when the media reach the end of file for example).

		enum vlc_player_abloop	abloop
	)

Enable A to B loop of the current media.

This function need to be called 2 times with VLC_PLAYER_ABLOOP_A and VLC_PLAYER_ABLOOP_B to setup an A to B loop. It current the current time/position when called. The B time must be higher than the A time.

Parameters

player locked player instance

Returns: VLC_SUCCESS or a VLC error code

◆ vlc_player_SetCurrentMedia()

int vlc_player_SetCurrentMedia	(	vlc_player_t *	player,
		input_item_t *	media
	)

Set the current media.

This function replaces the current and next medias.

Note: A successful call will always result of vlc_player_cbs.on_current_media_changed being called. This function is not blocking. If a media is currently being played, this media will be stopped and the requested media will be set after.

Warning: This function is either synchronous (if the player state is STOPPED) or asynchronous. In the later case, vlc_player_GetCurrentMedia() will return the old media, even after this call, and until the vlc_player_cbs.on_current_media_changed is called.

Parameters

player	locked player instance
media	new media to play (will be held by the player)

Returns: VLC_SUCCESS or a VLC error code
