RV Cookbook - How to get things done with RV in Python

Getting the file name (and path) of the frame currently being played

@Michael.Kessler

import rv

# The difference here is that we traverse the graph to find not only the source, but also the source frame number.
info = rv.extra_commands.sourceMetaInfoAtFrame(rv.commands.frame())
metadata =  rv.commands.sourceMediaInfo(info['node'])
filename = metadata.get("file")
sourceFrame = info['frame']

# Note: this only works how we want it to for file sequences, error check to make sure you are dealing in file sequencese, as well as protecting yourself against missing framees.
files = rv.commands.existingFilesInSequence(filename)
frames = rv.commands.existingFramesInSequence(filename)

# Assmeble the files and frame numbers in something we can index into.
framesToFiles = dict(zip(frames, files))


# The result can be found here:
framesToFiles[sourceFrame]
