media-info

Analyze media files with MediaInfo CLI and compare behavior with ffprobe. Use when inspecting container/codec metadata, extracting width/height/duration/bitrate, troubleshooting files that ffprobe cannot parse, or classifying media by orientation (landscape/portrait).

Install and run MediaInfo CLI in non-root environments.

Quick start

1. Install MediaInfo locally:
   • bash scripts/install_mediainfo_local.sh
2. Verify installation:
   • bash scripts/test_mediainfo.sh
3. Inspect files:
   • ./vendor/mediainfo/MediaInfo/Project/GNU/CLI/mediainfo <file>
   • ./vendor/mediainfo/MediaInfo/Project/GNU/CLI/mediainfo --Output=JSON <file>

Workflow

Install

Run scripts/install_mediainfo_local.sh.

• Download MediaInfo source archive
• Build CLI locally
• Place binary at vendor/mediainfo/MediaInfo/Project/GNU/CLI/mediainfo

Extract metadata

Use plain output for human reading and JSON output for automation.

Classify orientation

Use Width/Height (and Rotation when present):

• landscape: effective width >= effective height
• portrait: effective width < effective height

When Rotation is 90/270, swap width and height before classification.

Notes

• Do not require sudo.
• Prefer MediaInfo for files where ffprobe fails but container data still exists.
