FFmpeg Helper

Use this skill when working with ffmpeg_kit_flutter_new.

1. Syntax Handling

• Space Escaping: Paths with spaces must be escaped.
  • Incorrect: -i /storage/emulated/0/My Folder/video.mp4
  • Correct: -i "/storage/emulated/0/My Folder/video.mp4"
• Codecs: Mobile devices often prefer aac for audio and libx264 (software) or h264_mediacodec (hardware) for video.

2. Common Recipes

Merge Audio and Video

final command = '-i "$videoPath" -i "$audioPath" -c:v copy -c:a aac "$outputPath"';
