pyqt-multimedia SKILL.md skillA
pyqt-multimedia from codeatcode/oss-ai-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add codeatcode/oss-ai-skills/pyqt-multimedia@v2.0.0Pins v2.0.0 in mdr.lock. Pin the fingerprint instead.

Use when adding multimedia to PyQt/PySide6 apps - audio and video playback with QMediaPlayer, camera capture with QCamera and QMediaCaptureSession, audio/video recording with QMediaRecorder, GStreamer backend setup, or codec and platform compatibility issues.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
> **Objective:** Use this skill to reduce playback-deadlock incidents, GStreamer-backend startup failures, codec-missing black-screen bugs, and recording-corruption incidents by enforcing backend-setup discipline, codec-availability checks, and platform-compatibility decision patterns below.
---
## Core Rules (do X because Y)
### Check GStreamer plugins before playback because missing codecs produce silent black video
On Linux, Qt Multimedia uses GStreamer as the backend. Missing plugins cause video to render as black screens without errors.
```bash
# Ubuntu/Debian - install ALL plugin groups before testing playback
sudo apt-get install libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev \
gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly \
gstreamer1.0-libav
# Verify plugins are loaded
gst-inspect-1.0 | grep -E "h264|mp3|aac"
```
**Failure mode:** Video loads, QMediaPlayer reports "no error", but screen stays black. Solution: install missing plugin packages, not just Qt bindings.
### Use QMediaCaptureSession not QMediaRecorder directly because the session owns the pipeline

How to install
mdr add codeatcode/oss-ai-skills/pyqt-multimedia@sha256:44142af8b211e008The line at the top of this page pins the label v2.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
