remotion-multimedia — Codex skill: use and install
This skill guides Mediabunny tasks in the browser, including reading audio and video duration and checking video dimensions.
npx skills add openai/plugins --skill remotion-multimedia -a codexWhat remotion-multimedia does
remotion-multimedia gives Codex focused guidance for using Mediabunny, a browser library for audio and video work. Its documented tasks cover three values: audio length in seconds, video length in seconds, and a video's width and height.
The skill includes separate guidance files named get-audio-duration.md, get-video-dimensions.md, and get-video-duration.md. Each one covers the matching measurement. It does not describe editing or encoding, so those workflows fall outside this skill's stated scope.
What it helps with
- read an audio file's duration in seconds
- check a video's width and height
- measure the duration of a video file
- inspect media metadata through Mediabunny
Example prompts for the agent
- Use Mediabunny to find the audio file's duration and report it in seconds.
- Check this video's width and height using the remotion-multimedia skill.
- Read the video duration with the matching Mediabunny guidance.
