create new playlist using python

[spicyacorn]

Hello!

I've written a user interface using fltk that allows a user to select one or more clips and load them into mrv.
Loading works using cmd.open(FILEPATH)

I would like to add the loaded clips to a new playlist using python, but there seems to be no way to create an empty timeline using the API.

Maybe I'm overlooking something?

Hi, welcome!

Yes, you are overlooking something: the power of python libraries. cmd.open() can be used to open also an OpenTimelineIO playlist.

As Pixar generously distributes the "opentimelineio" module through pip, you would need to, roughly do:

try:
    import opentimelineio as otio
except ImportError:
    print(f'''
Python's opentimelineio module not found!

Please run:
    pip install opentimelineio
''', file=sys.stderr)
    exit(1)
    
 timeline = otio.schema.Timeline()
 stack = otio.schema.Stack()
 track = otio.schema.Track()
 clip1 = otio.schema.Clip()  # Fill this with your clip media_reference info
 clip2 = otio.schema.Clip()
 
#
# Create a track on stack
#
 stack.append(track)
 
#
#  Append clips to the track
#
 track.append(clip1)
 track.append(clip2)
 
 #
 # Add stack to timeline
 #
 timeline.tracks = stack
 
 timeline.to_json_file("/tmp/test.otio")
 cmd.open("/tmp/test.otio")
