OSC Video Player

The video playback is organized in slots. Each slot can load a specific video file. and there is only one slot visible at any time. Playback is organized following the paradigm of a stack: if slot 1 is playing and playback for slot 2 is triggered, slot 2 starts playing and takes over the display. If slot 1 keeps playing and slot 2 is stopped, the display returns to slot 1.

Every aspect of playback (start, stop, speed, position) can be controlled via OSC. Scripts can also be loaded via OSC. Alternatively a folder can be loaded either via OSC or from the command line. In that case, clips in the folder must be organized as shown below, where each clip has a prefix indicating the slot where it should be loaded.

Load all clips from a folder

media/
  001_cat.mp4
  002_dog.mp4
  004_brid.mp4

OSC-Video-Player --folder $(realpath media)

This will load each clip to the specified slot (1, 2, 4 in this case)

OSC messages accepted:

/load slot:int path:str
    * Load a video at the given slot. The path must be absolute

/play slot:int [speed:float=1] [starttime:float=0] [paused:int=0] [stopWhenFinished:int=1]
    * Play the given slot with given speed, starting at starttime (secs)

      paused: if 1, the playback will be paused
      stopWhenFinished: if 1, playback will stop at the end, otherwise it
        pauses at the last frame

/stop [slot:int]
    * Stop playback. If no slot is given, the currently playing slot is stopped

/pause state:int
    * If state 1, pause playback, 0 resumes playback

/setspeed speed:float
    * Change the speed of the playing slot

/scrub pos:float [slot:int=current]
    * Set the relative position 0-1. Sets the given slot as the current slot
      In scrub mode, video is paused and must be driven externally

/scrubabs timepos:float [slot:int=current]
    * Set the absolute time and activates the given slot. In scrub mode, video
      is paused and must be driven externally

/setpos
     * Sets the relative (0-1) playing position of the current clip
       (does not pause the clip like /scrub)

/settime
     * Sets the absolute playing position of the current clip
       (does not pause the clip like /scrubabs)

/dump
    * Dump information about loaded clips

/quit
    * Quit this application
