weaver

Weaver is a command-line tool that allows you to manipulate video and audio files in various ways. You can create video chunks from image and audio, unite video chunks, split audio into chunks, merge audio into video, remove segment from video, remove segments from video, and clip segments from video.

Installation

To install Weaver, you need to have node.js installed on your system. Then, you can run the following command:

npm install weaver-avi

Usage

To use Weaver, you need to invoke the weaver command with the appropriate options and arguments. You can also use the --help option to display the help menu for the main command or any subcommand.

The general syntax is:

weaver [options] [command] [arguments]

The available options are:

• -h or --help: display the help menu
• -v or --version: show the app version
• -c or --clean: clean up the temporary directory

The available commands are:

• create-video: create video from image and audio
• create-videos: create video chunks from image and audio
• unite-videos: unite video chunks
• split-audio: split audio into chunks
• merge-av: merge audio into video
• remove-segment: remove segment from video
• remove-segments: remove segments from video
• clip-segments: clip segments from video
• self-test: self-test built-in methods

Each command has its own options and arguments, which you can see by using the --help option with the command name. For example, to see the help menu for the create-videos command, you can run:

weaver create-videos --help

Examples

Here are some examples of how to use Weaver for different tasks:

• To create video from image and audio, you can run:

weaver create-video -s=image.png -a=audio.m4a -t=400

This will create video named output.mp4 in the temporary directory, using the image image.png and the audio audio.mp3.

• To create video chunks from image and audio, you can run:

weaver create-videos -c=slides.csv

This will create video chunks named vid_1.mp4, vid_2.mp4, etc. in the temporary directory, using the image and the audio file path given in the slides.csv file.

• To unite video chunks, you can run:

weaver unite-videos -c=videos.txt

This will unite all the video chunks that match the pattern output_*.mp4 and create a single video file named final.mp4 in the temporary directory.

• To split audio into chunks, you can run:

weaver split-audio -c=chunks.csv -a=audio.m4a

This will split the audio audio.m4a into chunks of 10 seconds each and create audio files named aud-1.m4a, aud-2.m4a, etc. in the temporary directory.

• To merge audio into video, you can run:

weaver merge-av -a=audio.m4a -v=video.mp4

This will merge the audio audio.m4a into the video video.mp4 and create a new video file named output.mp4 in the temporary directory.

• To remove a segment from a video, you can run:

weaver remove-segment -v=video.mp4 -b=100 -e=200

This will remove the segment, say from 100 seconds to 200 seconds from the video video.mp4 and create a new video file named output.mp4 in the temporary directory.

• To remove multiple segments from a video, you can run:

weaver remove-segments -c=segments.csv -v=video.mp4

This will remove the segments, say from 30 seconds to 60 seconds and from 90 seconds to 120 seconds from the video video.mp4 and create a new video file named output.mp4 in the temporary directory.

• To clip multiple segments from a video, you can run:

weaver clip-segments -c=segments.csv -v=video.mp4

This will clip the segments, say from 30 seconds to 60 seconds and from 90 seconds to 120 seconds from the video video.mp4 as specified in segments.csv file and create video file named output.mp4 by consolidating all the segments in the temporary directory.

• To self-test the built-in methods, you can run:

weaver self-test

This will run a series of tests on the built-in methods and display the results.

Troubleshoot

If you encounter any problems or errors while using Weaver, you can use the --help option to see the usage and options for each command. You can also use the self-test command to check if the built-in methods are working properly. If you still need help, log it in issues section.
