/install screen-record-frames
功能描述
Record Android screen via scrcpy, dynamically set keyframe intervals with ffmpeg, then extract and list key frames as PNG images.
安全使用建议
This skill appears to be what it claims: it records an Android device with scrcpy and extracts key frames with ffmpeg. Before installing/running: review scripts/install.sh because it will prompt to install packages and (on Linux) add you to plugdev and write /etc/udev/rules.d/51-android.rules (requires sudo). Only run the install script if you trust these changes; consider running the workflow manually if you prefer (install adb/scrcpy/ffmpeg via your package manager and run scripts/main.sh commands). Verify packages come from your distro's or Homebrew repositories, and back up any system udev rules if you are concerned. If you only want to run extraction against existing videos, you can skip the install and recording steps and run the extract-frames command on local files.
功能分析
Type: OpenClaw Skill
Name: screen-record-frames
Version: 1.0.0
The skill provides a legitimate utility for recording Android screens via scrcpy and extracting keyframes using ffmpeg. The scripts (scripts/main.sh, scripts/install.sh) are transparent, well-documented, and perform actions strictly aligned with the stated purpose. While the installation script requires sudo on Linux to configure udev rules for USB access, this is a standard requirement for Android debugging and does not show signs of malicious intent or unauthorized persistence.
能力评估
Purpose & Capability
Name/description (record Android screen, set keyframe interval, extract key frames) align with the included scripts and README. The scripts legitimately require adb, scrcpy, ffmpeg and perform the described operations.
Instruction Scope
SKILL.md and scripts instruct only local actions: checking for tools, using scrcpy to record, using ffmpeg/ffprobe to analyze and re-encode, and listing PNGs. The scripts probe the connected device (adb devices, getprop) which is expected for this use case. There are no external network endpoints, hidden uploads, or instructions to read unrelated system files.
Install Mechanism
There is no remote code download, but scripts/install.sh performs system changes: installing packages (brew/apt), adding the user to plugdev, writing a udev rules file to /etc/udev/rules.d and reloading rules. These are expected to enable USB access to Android devices but require sudo/admin rights and will modify system configuration.
Credentials
No credentials or sensitive environment variables are requested. Only optional env vars are KEYFRAME_INTERVAL and OUTPUT_DIR which are appropriate for the task.
Persistence & Privilege
The skill does not request persistent automatic inclusion (always:false) and does not modify other skills. However, the install script requires and uses elevated privileges (sudo) to modify udev rules and groups — a necessary but privileged action to access USB devices.
