Mpeg4-Dash-Video-Converter

This Bash script automates the process of converting video files to MPEG-DASH compatible files. It is designed to cater to users with varying internet connection speeds, ensuring the best possible quality for each user's bandwidth.

Features

• Converts input video files into multiple bitrate versions for both video and audio.
• Supports custom framerate, minimum and maximum CRF values, resolution steps, and encoding preset.
• Generates MPEG-DASH compatible files for adaptive streaming.
• Automatically detects and uses the original video resolution.
• Provides a simple command-line interface with customizable options.
• Optional x265 encoding for HEVC compatibility.

Usage

To use the script, follow these steps:

1. Install the script

   bash <(curl -sL https://raw.githubusercontent.com/Mythli/mpeg-dash-converter/main/src/download.sh)
   

2. Run the script with the desired options and input video files:

   dashify [options] <input_files...>
   

   Available options:

   • --framerate <rate>: Set the framerate for the output videos (default: 24).
   • --min-crf <value>: Set the minimum CRF value for the highest quality level (default: 22).
   • --max-crf <value>: Set the maximum CRF value for the lowest quality level (default: 28).
   • --steps <number>: Set the number of resolution steps for the output videos (default: 4).
   • --preset <preset>: Set the x264 encoding preset (default: slower).
   • --x264: Encode with x264 (highest compatibility)
   • --x265: Encode with x265 (highest compression)

   Example usage:

   dashify.sh --framerate 24 --min-crf 18 --max-crf 28 --steps 4 --preset fast --x265 --x264 video1.mp4 video2.mp4
   

3. The script will process each input video file and generate the corresponding multi-bitrate versions and MPEG-DASH files in a separate directory named <video_name>.dash.

Customization

You can customize the default values for the script by modifying the following variables at the beginning of the script:

• default_framerate: The default framerate for the output videos (default: 24).
• default_min_crf: The default minimum CRF value for the highest quality level (default: 22).
• default_max_crf: The default maximum CRF value for the lowest quality level (default: 28).
• default_steps: The default number of resolution steps for the output videos (default: 4).
• default_preset: The default x264 encoding preset (default: slower).
• default_x265: The default setting for x265 encoding (disabled by default).
• default_x264: The default setting for x264 encoding (disabled by default).

Feel free to adjust these values according to your specific requirements.

Using x265 on macOS

If you are using macOS, you will need to install ffmpeg with x265 support. You can do this using Homebrew by running the following commands:

brew uninstall ffmpeg
brew tap homebrew-ffmpeg/ffmpeg
brew install homebrew-ffmpeg/ffmpeg/ffmpeg --with-xvid --with-fdk-aac
