Implements a new feature in the Streamlit application to "Extend Video Length". Key changes: - Added UI elements for video upload, specifying extension duration, and triggering the process. - Implemented `extend_video_placeholder`, a function that simulates video extension by saving and copying the uploaded video. This serves as a stand-in for a future AI-based extension model. - Integrated this placeholder function into the app: you can upload a video, specify an extension duration, and see a mock "extended" video displayed. - Ensured necessary dependencies (FFmpeg, OpenCV) are checked and installed. - Included basic error handling and user feedback messages throughout the new workflow. - Updated `README.md` to describe the new feature and overall application functionality. The core video extension logic is currently a placeholder. Future work will involve replacing this with an actual AI model for video extension.
It's now a standalone command-line tool (`extend_video_cli.py`) instead of being part of the Streamlit UI.
Here's a summary of the key changes:
- I created `extend_video_cli.py`:
- This script uses `argparse` to handle command-line arguments like `--input_path`, `--duration`, and `--output_path`.
- It includes the `extend_video_file` function (which I adapted from the previous `extend_video_placeholder`). This function simulates extending a video by copying the input file. I've replaced the Streamlit-specific parts with console output.
- The main logic in this script validates your input, calls `extend_video_file`, and then either moves the output to the path you specified or tells you the temporary path.
- I modified `streamlit_app.py`:
- I removed all the UI elements (like the header, input fields, and button) that were related to extending video length.
- I deleted the `extend_video_placeholder` function and its associated logic.
- Now, the Streamlit app is focused only on the search functionalities.
- I updated `README.md`:
- I removed the description of how to extend videos using the Streamlit UI.
- I added a new section that explains how to use `extend_video_cli.py`, including usage examples and descriptions of the arguments.
This change addresses your feedback to make the video extension functionality available 'without streamlit', offering a more flexible command-line interface.
