ERROR:root:* MakeFrameDataset

[Aljnk]

Hi. I can't add custom string (try many other) to MakeFrameDataset Node

Log

WF

Work only in I write same path inside

The problem is in this code:

@classmethod
    def VALIDATE_INPUTS(self, file_path, update_on_frame_load):
        _, n_frames = self.get_frames(self, file_path, update_on_frame_load)
        if n_frames==0:
            return f"Found 0 frames in path {file_path}"

        return True

If you delete it - everything works.
file_path is always NONE within VALIDATE_INPUTS - Perhaps the problem is that this function does not have enough time to get the value from connected node.

if delete VALIDATE_INPUTS and add validation inside get_frames - it won't be as pretty, but it will work

def get_frames(self, file_path, update_on_frame_load):
        ds = FrameDataset(file_path, outdir_prefix='', videoframes_root=folder_paths.get_output_directory(), 
                          update_on_getitem=update_on_frame_load)
        if len(ds) == 0:
            return f"Found 0 frames in path {file_path}"
        return (ds,len(ds))
