1. Download the latest release.
   • HLSConverter-MacOS_ARM.app.zip → for Apple Silicon (M1/M2/M3/M4).
   • HLSConverter-MacOS_Intel.app.zip → for Intel-based Macs.
2. Extract the .zip file and move HLSConverter.app to your Applications folder.
3. On first launch, macOS may block the app because it's unsigned:
   • Go to System Preferences → Security & Privacy → General.
   • Click Allow Anyway, then reopen the app.

1. Download the latest release (HLSConverter-Windows.exe).
2. Double-click the .exe to start converting videos.
   • No Python or FFmpeg installation is required; everything is bundled.

If you prefer to build the application manually:

(Python is needed for the build application)

1. Clone the repository:

   git clone https://github.com/yourusername/HLS-Converter.git
   cd HLS-Converter

2. Install Python dependencies:

   pip install -r requirements.txt

3. Download FFmpeg binaries for all platforms:

   • From the realese page download the latest bin.zip and extract the bin folder.
   • From the bin folder get ffmpeg and ffprobe files for your platform.
   • Place the ffmpeg and ffprobe for your platform at the root of the bin folder:

     bin/
      ├─ ffmpeg (or .exe on Windows)
      ├─ ffprobe (or .exe on Windows)
     

   Each folder bin should contain both ffmpeg and ffprobe (or .exe on Windows).

4. Build standalone apps:

   • macOS:

     pyinstaller --onefile --windowed --icon=icon.icns --add-binary "bin/ffmpeg:bin" --add-binary "bin/ffprobe:bin" --hidden-import=tkinterdnd2 HLSconverter.py

   • Windows:

     pyinstaller --onefile --windowed --noconsole --icon=icon.ico --add-binary "bin/ffmpeg.exe;bin" --add-binary "bin/ffprobe.exe;bin" --hidden-import=tkinterdnd2 --add-data "icon.ico;." HLSconverter.py

After the build process the portable application should be in the dist folder

• Each converted video gets its own folder inside the chosen output directory.
• Contains:
  • output.m3u8
  • .ts video segments for HLS streaming.
  • thumbnail.jpg preview image.
