Requirements

  • Python3
  • PortAudio (Only required for installation with audio support)
  • FFmpeg (Only required for installation with audio support)
  • Linux or MacOS ... by now

Installation

Standard installation

$ pip3 install video-to-ascii

With audio support installation

$ pip3 install video-to-ascii --install-option="--with-audio"

How to use

Just run video-to-ascii in your terminal

$ video-to-ascii -f myvideo.mp4

Options

--strategy Allow to choose an strategy to render the output.

Render Strategies

-o --output Export the rendering output to a bash file to share with someone.

Exporting

-a --with-audio If an installation with audio support was made, you can use this option to play the audio track while rendering the video ascii characters.

How it works

Every video is composed by a set of frames that are played at a certain frame rate.

Video Frames

Since a terminal has a specific number of rows and columns, we have to resize our video to adjust to the terminal size limitations.

Terminal

To reach a correct visualization of an entire frame we need to adjust the frame height to match the terminal rows, avoiding using more characters than the number of terminal columns.

Resizing

When picking a character to represent a pixel we need to measure the relevance of that pixel's color in the frame, based on that we can then select the most appropriate character based on the relative luminance in colorimetric spaces, using a simplify version of the luminosity function.

Green light contributes the most to the intensity perceived by humans, and blue light the least.

This function returns an integer in the range from 0 to 255, we assign a character according to density to show more colored surface for areas with more intense color (highest values).

CHARS_LIGHT 	= [' ', ' ', '.', ':', '!', '+', '*', 'e', '$', '@', '8']
CHARS_COLOR 	= ['.', '*', 'e', 's', '@']
CHARS_FILLED    = ['░', '▒', '▓', '█']

The reduced range of colors supported by the terminal is a problem we need to account for. Modern terminals support up to 256 colors, so we need to find the closest 8 bit color that matches the original pixel in 16 or 24 bit color, we call this set of 256 colors ANSI colors.

The Mapping of RGB and ANSI Colors

8 Bits Color Table

Finally, when putting it all together, we will have an appropriate character for each pixel and a new color.

    time.clock() has been removed in Python3.8

    Hi, I run this program to watch some video on macOS. But I encounter problem: AttributeError: module 'time' has no attribute 'clock'.

    After I search that, I know: time.clock() has been removed in Python3.8.

    I have checked the related line of file, and replace it with time.process_time(). Then it works well. Maybe need to use other API on other OS. https://github.com/joelibaceta/video-to-ascii/blob/5c812d5e7fd9466050dcdd6d4441ce077f2378d8/video_to_ascii/render_strategy/ascii_strategy.py#L120

    Errors with included executable file

    Installing on macos Mojave using the system pip and python yields the following error on execution:

    ❯ video-to-ascii
    /usr/local/bin/video-to-ascii: line 3: import: command not found
    from: can't read /var/mail/video_to_ascii
    /usr/local/bin/video-to-ascii: line 6: syntax error near unexpected token `('
    /usr/local/bin/video-to-ascii: line 6: `CLI_DESC = ("It is a simple python package to play videos in the terminal"'
    

    On a closer look, it's because the file bin/video-to-ascii is missing the ! from the shebang line, which should read like so:

    #!/usr/bin/env python
    

    Furthermore, you'll also want to include a line like this:

    # coding=utf-8
    

    Otherwise, I get this error:

    258 ❯ video-to-ascii
