Node: JSON URL Loader @ vrch.ai (vrch.ai/text)

1. Add the JSON URL Loader @ vrch.ai node to your ComfyUI workflow.

2. Configure the Node:

   • URL:
     • url: Provide the URL from which the node will load JSON content.
   • Optional Settings:
     • print_to_console: Toggle this option to print the loaded JSON to the console for debugging purposes.

3. Load JSON:

   • The node sends a GET request to the specified URL with a 5-second timeout.
   • Upon success, it parses the response into a JSON object.
   • In case of a request failure or if the JSON is invalid, the node outputs an empty JSON object ({}).
   • If enabled, the node prints a formatted version of the JSON to the console for inspection.

Note:

• Ensure that the URL is accessible and returns valid JSON data.

Node: TEXT SRT Player @ vrch.ai (vrch.ai/text)

1. Add the TEXT SRT Player @ vrch.ai node to your ComfyUI workflow.

2. Configure the Node:

   • SRT Text Input:
     • srt_text: Provide the SRT-formatted text containing subtitle timing and content. The text should follow proper SRT formatting.
   • Placeholder Text:
     • placeholder_text: Specify the text that will be output when no subtitle is active (i.e., when current_selection is set to -1).
   • Loop:
     • loop: Toggle this option to enable or disable looping playback of the SRT file.
   • Current Selection:
     • current_selection: This integer value is automatically updated during playback to indicate the currently active subtitle. When the playback time is outside any subtitle interval, the value is set to -1 so that the placeholder text is output.
   • Debug:
     • debug: Enable debug mode to print detailed parsing and playback logs to the console.

3. Play SRT Text:

   • The node uses an SRT parsing library to convert the provided SRT text into subtitle entries.
   • It then plays the subtitles by continuously updating the current_selection based on the current playback time.
   • The node provides interactive controls:
     • Play/Pause: A button that toggles between playing and pausing the subtitle playback. The button text updates to reflect the current state.
     • Reset: A button that resets the playback time to the beginning.
   • A small display shows the current playback time in seconds.
   • When looping is enabled, playback automatically restarts from the beginning upon reaching the end of the last subtitle entry.

Note:

• Ensure that the SRT text follows the correct SRT formatting standard.
• The node outputs the content of the selected subtitle (or the placeholder text when no subtitle is active) to subsequent nodes in your workflow.
