Run brightscript on UDP input

Hello,
I have been looking for a solution for when a video is playing and a user pushes a button on an external device that sends a UDP string to the player will jump the current playing video back by 30 seconds for example.

I have had a look at the documentation and I have written the following - i could be way off the mark with this however.
The idea is that the trigger reads current position, then sets it back by 30 seconds.
I am however unsure first if this script is correct and then secondly, how to link a UDP message input to trigger a custom script

videoPlayer = CreateObject("roVideoPlayer")

   

' Assuming the video is already playing

' Get the current position of the video

currentPosition = videoPlayer.GetPlaybackPosition()

' Calculate the new position, 30 seconds earlier

newPosition= currentPosition-30000

' BrightScript measures time in milliseconds

' Ensure the new position is not negative

    if newPosition < 0 then

        newPosition = 0

    end if

' Seek to the new position

    videoPlayer.Seek(newPosition)

' Call the function to rewind the video

  Try looking at this: https://github.com/brightsign/BrightAuthor-Plugins/tree/master/Rotate-and-Seek

  Hi Shaun,

  Thankyou for your reply.  I have had a look at this plugin, i does look like I could implement a 'rewind' type function.  It does also look good for seeking to a pre-defined point of the video which I can look at implementing.  However I was wondering if there is also a solution to be able to query the current playing video time and then jump back 30 seconds from that point.

  I can't remember if you can seek backwards with that command so you'll just have to test it out. In the code snippet you provided you're already calling current time and subtracting 30s so you have everything you need.

  Add your extra logic around Lines 240 and Lines 249 where the existing Seek commands are.

  videoPlayer.Seek(newPosition) # activates immediately

  My only suggestion is calling GetDuration() to ensure you don't go over the end of the file.

  Only gotcha I can see is if you're doing a seamless loop but that wouldn't be that hard to calculate by getting the video duration.

  Excellent thankyou, I will have a good with the intial plugin and then see if I can integrate my code to get the predefined jump times working.
