mp3cd

Mp3c implementation written in Dart.

Details

Convert audio, images, text, and videos for specific portable media players. Profiles were meticulously reverse-engineered for optimal conversion. List of profiles are available through this spreadsheet.

Binary paths

Binaries are assumed to be in your PATH, but can be overridden on a library-level. These are the defaults:

/// Binary path for FFmpeg.
String binPathFfmpeg = 'ffmpeg';

/// Binary path for FFprobe.
String binPathFfprobe = 'ffprobe';

/// Binary path for FFmpeg with YP3 x264 patch.
String binPathFfmpegYp3Patch = 'ffmpeg-yp3-patch';

/// Binary path for Image Magick convert.
String binPathImageMagick = 'convert';

/// Binary path for ebook-convert.
String binPathEbookConvert = 'ebook-convert';

/// Binary path for MP4Box.
String binPathMp4box = 'MP4Box';

YP3

Certain MP3 players using the SmartLink 6806 (SL6806) chipset require special x264 patches and thus a special patched ffmpeg binary for x264 video conversion. Ensure the ffmpeg binary can be located in your PATH named ffmpeg-yp3-patch.

Dependencies

Ensure these dependencies are available through your environment:

• ffmpeg
• ffmpeg-yp3-patch
• ffprobe
• ebook-convert (Calibre)
• convert (Image Magick)
• MP4Box (gpac)
