tkVideoUtils - Python module for playing videos and camera feeds in a Tkinter label, with recording functionality

About The Project

tkVideoUtils is a Python module for playing and recording videos in GUIs created with tkinter. Using imageio-ffmpeg, webcams can be indexed and streamed in a tkinter Label. They can also be recorded (in their original resolution) by calling the start_recording() function! This project was heavily inspired by huskeee's tkvideo library, check their project out!

Built With

• tkinter (Python built-in)
• imageio
• imageio-ffmpeg
• Pillow
• opencv-python
• moviepy
• ffmpy
• PyAudio

Installation

End-users:

• Clone the repo and run setup.py

git clone https://github.com/wsarce/tkVideoUtils.git
python ./tkvideo/setup.py

or

• Install the package from PyPI

pip install tkVideoUtils

Developers and contributors

• Clone the repo and install the module in developer mode

git clone https://github.com/wsarce/tkVideoUtils.git
python ./tkvideo/setup.py develop

or

• Install the package from PyPI in editable mode

pip install -e tkvideoplayer

This will create a shim between your code and the module binaries that gets updated every time you change your code.

Usage

Playing a Video in a Label

from tkinter import *

from ttkwidgets import TickScale

from tkvideoutils import VideoPlayer
from tkinter import filedialog, messagebox


def on_closing():
    player.loading = False
    root.quit()
    root.destroy()


if __name__ == '__main__':
    # create instance of window
    root = Tk()
    # set window title
    root.title('Video Player')
    # load images
    pause_image = PhotoImage(file='pause.png')
    play_image = PhotoImage(file='play.png')
    skip_backward = PhotoImage(file='skip_backward.png')
    skip_forward = PhotoImage(file='skip_forward.png')
    # create user interface
    button = Button(root, image=play_image)
    forward_button = Button(root, image=skip_forward)
    backward_button = Button(root, image=skip_backward)
    video_label = Label(root)
    video_path = 'recorded_video.mp4'
    audio_path = 'recorded_video.wav'
    slider_var = IntVar(root)
    slider = TickScale(root, orient="horizontal", variable=slider_var)
    # place elements
    video_label.pack()
    button.pack()
    forward_button.pack()
    backward_button.pack()
    slider.pack()

    if video_path:
        # read video to display on label
        player = VideoPlayer(root, video_path, audio_path, video_label, size=(700, 500),
                             play_button=button, play_image=play_image, pause_image=pause_image,
                             slider=slider, slider_var=slider_var, keep_ratio=True, cleanup_audio=True)
    else:
        messagebox.showwarning("Select Video File", "Please retry and select a video file.")
        sys.exit(1)
    player.set_clip(50, 70)
    forward_button.config(command=player.skip_video_forward)
    backward_button.config(command=player.skip_video_backward)
    root.protocol("WM_DELETE_WINDOW", on_closing)
    root.mainloop()

Playing and Recording a Webcam in a Label

from tkinter import *
from tkvideoutils import VideoRecorder
from tkinter import messagebox

    if player.merge_sources(merged_path, ffmpeg_exe):
        print("Sources merged!")
    else:
        print("Something went wrong")


def stop_recording():
    player.stop_recording()
    player.stop_playback()
    button['command'] = merge_sources


def start_recording():
    player.start_recording()
    button['command'] = stop_recording


if __name__ == '__main__':
    # create instance of window
    root = Tk()
    # set window title
    root.title('Video Player')
    # load images
    pause_image = PhotoImage(file='pause.png')
    play_image = PhotoImage(file='play.png')
    # create user interface
    button = Button(root, image=play_image)
    video_label = Label(root)
    video_path = 'raw_video.mp4'
    audio_path = 'recorded_video.wav'
    merged_path = 'recorded_video.mp4'
    # place elements
    video_label.pack()
    button.pack()
    # Get existing video sources
    video_sources = VideoRecorder.get_video_sources()
    audio_sources = VideoRecorder.get_audio_sources()
    print(video_sources, audio_sources)
    # TODO: Fill out FFMPEG path
    ffmpeg_exe = r''

    if video_sources:
        if video_path:
            # read video to display on label
            player = VideoRecorder(video_source=video_sources[0], audio_source=audio_sources[1],
                                   video_path=video_path, audio_path=audio_path, fps=8, label=video_label,
                                   size=(700, 500))
            player.start_playback()
        else:
            messagebox.showwarning("Select Video File", "Please retry and select a video file.")
            sys.exit(1)
        button.config(command=start_recording)
        root.mainloop()
    else:
        print("No video sources found!")

Notes on Freezing

If you want to freeze your Python scripts that reference tkVideoUtils, there are some general notes to keep in mind:

• Due to the use of ImageIO, the lazy import error causes frozen Python scripts to fail to start or fail to execute the imageio codepaths. This can make it look like imageio-ffmpeg is failing with a backend issue. To circumvent this, follow this answer. This answer says to overwrite your imageio folder in your exe output directory with the imageio folder from your virtual environment (venv\Lib\site-packages\imageio). I can verify that this works.
• I prefer copying the ffmpeg exe version that is packaged with imageio-ffmpeg into your exe directory in a known folder and updating os.environ['IMAGEIO_FFMPEG_EXE'] with that directory. This ensures a known path.
