media-processing
Process multimedia files with FFmpeg (video/audio encoding, conversion, streaming, filtering, hardware acceleration), ImageMagick (image manipulation, format conversion, batch processing, effects, composition), and RMBG (AI-powered background removal). Use when converting media formats, encoding videos with specific codecs (H.264, H.265, VP9), resizing/cropping images, removing backgrounds from images, extracting audio from video, applying filters and effects, optimizing file sizes, creating streaming manifests (HLS/DASH), generating thumbnails, batch processing images, creating composite images, or implementing media processing pipelines. Supports 100+ formats, hardware acceleration (NVENC, QSV), and complex filtergraphs.

Media Processing Skill
Process video, audio, and images using FFmpeg, ImageMagick, and RMBG CLI tools.
Tool Selection
| Task | Tool | Reason |
|---|---|---|
| Video encoding/conversion | FFmpeg | Native codec support, streaming |
| Audio extraction/conversion | FFmpeg | Direct stream manipulation |
| Image resize/effects | ImageMagick | Optimized for still images |
| Background removal | RMBG | AI-powered, local processing |
| Batch images | ImageMagick | mogrify for in-place edits |
| Video thumbnails | FFmpeg | Frame extraction built-in |
| GIF creation | FFmpeg/ImageMagick | FFmpeg for video, ImageMagick for images |
Installation
# macOS
brew install ffmpeg imagemagick
npm install -g rmbg-cli
# Ubuntu/Debian
sudo apt-get install ffmpeg imagemagick
npm install -g rmbg-cli
# Verify
ffmpeg -version && magick -version && rmbg --version
Essential Commands
# Video: Convert/re-encode
ffmpeg -i input.mkv -c copy output.mp4
ffmpeg -i input.avi -c:v libx264 -crf 22 -c:a aac output.mp4
# Video: Extract audio
ffmpeg -i video.mp4 -vn -c:a copy audio.m4a
# Image: Convert/resize
magick input.png output.jpg
magick input.jpg -resize 800x600 output.jpg
# Image: Batch resize
mogrify -resize 800x -quality 85 *.jpg
# Background removal
rmbg input.jpg # Basic (modnet)
rmbg input.jpg -m briaai -o output.png # High quality
