VLC trigger action when media reaches timestamp

I'd like to the ability to run some code when the timestamp of a file has been reached (i.e. trigger an alert)

How can this be achieved?

I was looking at this https://www.geeksforgeeks.org/python-vl ... edia-time/

However, I feel like I'm really looking for some kind of daemon (i.e. start the media file with VLC and then have this "listener" perform an action when timestamp on vlc has been reached)

I'm not opposed to pulling down the code, modifying changes to add a hook, and re-compiling to get what I need. I just need some pointers on where in the codebase this would all live.

What direction may I be pointed to to achieve this? Thanks!

Solution

You want the EventManager class, the documentation for which can be found here. Here's an example of how to use it to notify you when a video stops playing.

import vlc

def callback(event, player):
    print('FPS:', player.get_fps())
    print('Time(ms):', player.get_time())
    print('Frame:', .001 * player.get_time() * player.get_fps())

# Create new media
inst = vlc.Instance()
media = inst.media_new('path/to/video')

# Create new instance of vlc player
player = inst.media_player_new()

# Add a callback
em = player.event_manager()
em.event_attach(vlc.EventType.MediaPlayerStopped, \
                callback, player)

# Load video into vlc player instance
player.set_media(media)

# Play media
player.play()

Edit: Could you try this code?

import vlc

def callback(player):
    print('FPS:', player.get_fps())
    print('Time(ms):', player.get_time())
    print('Frame:', .001 * player.get_time() * player.get_fps())
    
    media_player.stop()

# creating vlc media player object
media_player = vlc.MediaPlayer()

# media object
media = vlc.Media("src/backtalk/default/oscar.mp4")

# setting media to the media player
media_player.set_media(media)

# start playing video
media_player.play()

while True:
    if media_player.get_state() == vlc.State.Ended:
        callback(media_player)
