OpenConverter

📢 Project Introduction

OpenConverter is software built on the FFmpeg source code, Qt open-source framework, and BMF framework. It provides simple and user-friendly tools to convert, edit, and process audio and video files.

The converter includes the following main features:

1. Supports changing video codecs for encoding (e.g., libx264, libx265).
2. Supports lossless multimedia conversion.
3. Displays information about video and audio streams in multimedia files.
4. Shows smooth progress tracking and accurate remaining time while converting files.
5. Allows runtime switching of transcoding cores (FFmpeg, FFTool, BMF).
6. Provides both GUI and Command Line Interface (CLI) for flexible usage.

This project is developed using the Qt framework, the FFmpeg library, and the BMF framework.

For FFmpeg development tutorials, refer to Learn FFmpeg the Hard Way.

🌟 Feature Details

After running OpenConverter, you can see and use the following features:

1. Support for Changing Audio and Video Codecs for Encoding (e.g., libx264, libx265, aac, ac3)

This converter allows users to easily change audio and video codecs. For example, you can choose to use the libx264 or libx265 encoder for higher compression rates and better video quality.

2. Support for Lossless Multimedia Conversion

The converter also supports lossless multimedia conversion. This means you can directly convert files from one format to another without re-encoding the original video and audio streams. This is very useful for quick file conversions.

3. Display Information About Video and Audio Streams

This converter can display detailed information about video and audio streams, including resolution, frame rate, bitrate, etc. This helps you understand the properties of multimedia files for making appropriate adjustments during conversion.

4. Advanced Progress Tracking and Time Estimation

During file conversion, the player provides:

• Smooth progress updates with UI-friendly refresh rates
• Accurate remaining time estimation using duration smoothing
• Real-time progress percentage and duration tracking
• Detailed console output for monitoring conversion status

5. Runtime Switching of Transcoding Cores (FFmpeg, FFTool, BMF)

The software offers three different transcoding cores to choose from:

• FFmpeg API-based core for direct library integration
• FFTool core for command-line tool integration
• BMF framework-based core for advanced processing You can also selectively compile these cores based on your needs.

6. Command Line Interface (CLI) Support

Usage in non-GUI mode:

./OpenConverter [options] input_file output_file

Options:
  -t, --transcoder TYPE    Set transcoder type (FFMPEG, BMF, FFTOOL)
  -v, --video-codec CODEC  Set video codec
  -a, --audio-codec CODEC  Set audio codec
  -h, --help               Show help message

Example:

# Convert video using FFmpeg core with H.264 video codec
./OpenConverter -t FFMPEG -v libx264 input.mp4 output.mp4

# Convert video using BMF core with H.265 video codec and AAC audio codec
./OpenConverter -t BMF -v libx265 -a aac input.mp4 output.mp4
