MKV script for handling a counter

[Iraito]

Ok i have a video of multiple drops of particles, i wanna use that video for a death counter, i was thinking if it was possible to add chapters to the mkv and create a script that plays one chapter, stops and with the press of a hotkey it would go to the next one.

I don't know how to do that *exactly*, but treating it as an XY problem got me this:

Load the original video into an editor, split it into the sections that you want, and save both the sections as their own videos and the still frames at each split point. Then put each of those sections into its own scene in OBS, and likewise for the still frames. Set up a series of macros in the Advanced Scene Switcher plugin, for each of the sections being done, and cut to the corresponding still frame. Then to show the next section, just cut to its scene.

Advanced Scene Switcher

This plugin will allow you to automate various tasks using "Macros". Macros consist of a list of conditions under which a list of actions will be performed. Examples and guides can be found in the wiki. Feel free to contribute! Currently...

Or if OBS hangs on the last frame, then you don't need the still images or the automation to show them.

I did something similar in the past, it was heavy as hell on resources, that's why i would like to use obs scripts and a way to simply play and stop a video, if i have to split 1000 drops in 1000 videos it's the end.

import time
import keyboard
 
 # Define the timestamps in hours, minutes, and seconds
timestamps = [
     (0, 0, 10),   # 00:00:10
     (0, 1, 30),   # 00:01:30
     (0, 3, 45)    # 00:03:45
 ]
 
 # Function to play media at a specific timestamp
def play_media(timestamp):
     # Convert the timestamp to seconds
     seconds = timestamp[0] * 3600 + timestamp[1] * 60 + timestamp[2]
    
     # Set the media playback position in OBS
     # Replace 'media_source' with the actual name of your media source in OBS
     obs.media_source_set_position('SaltCounter', seconds)
    
     # Start playing the media
     obs.media_play('SaltCounter')
 
 # Loop through the timestamps and play media at each timestamp
for timestamp in timestamps:
     # Play media at the current timestamp
     play_media(timestamp)
    
     # Pause the script for 2 seconds
     time.sleep(2)
    
     # Pause the media playback
     obs.media_pause('SaltCounter')
    
     # Wait for the hotkey to resume playback
     keyboard.wait('space')
    
     # Resume the media playback

So this script should do the job but i'm having issues:

[Salt_counter.py] Traceback (most recent call last):
[Salt_counter.py] File "C:\Salt_counter.py", line 26, in <module>
[Salt_counter.py] play_media(timestamp)

You haven't defined what "obs" is yet. So python doesn't recognize it.

You'll need to import it, but it escapes me now, what it's actually called to import.

 

[Iraito]

Yeah that seems to be the thing that's blocking me from having the script functioning, i really need this script to work.

 

[Iraito]

I solved it outside of OBS, a kind soul created a script to stop MPV at every chapter, it works really well but i would still like to see a script that handles something this simple directly in OBS.

Someone just happened to post it:

Python - Modifying Window Capture Settings

I'm trying to write a script to automatically update the Window Capture window when a user changes the current foreground window in Windows. This would eliminate the need to constantly change the currently selected window for recording or for replay buffer. I'm able to use obs_data_set_string...

import obspython as obs

If you want to come back to this, see if that works.
