RTSP Snapshot

This skill uses ffmpeg to capture a single, high-quality still frame from a network RTSP stream.

Usage

Execute the following shell command. Replace <RTSP_URL> with the full RTSP connection string for your camera and <OUTPUT_FILE> with the desired output path (e.g., ~/.openclaw/media/rtsp-snapshots/living-room.jpg).

Recommended Command

ffmpeg -y -rtsp_transport tcp -i "<RTSP_URL>" -ss 00:00:01 -vframes 1 -q:v 8 -colorspace smpte170m -color_primaries smpte170m -color_trc smpte170m "<OUTPUT_FILE>"

Command Breakdown

-y: Overwrite the output file without asking.
-rtsp_transport tcp: Forces the stream to use TCP instead of UDP. This is more reliable and prevents corrupted or incomplete images, especially over Wi-Fi or congested networks.
-i "<RTSP_URL>": Specifies the input RTSP stream URL.
-ss 00:00:01: Seeks 1 second into the stream before capturing the frame. This gives the stream time to stabilize and avoids capturing a black or garbled initial frame.
-vframes 1: Captures exactly one video frame and then stops.
-update 1: Overwrites the single output file, which is the correct way to handle single-frame grabs.
-q:v 8: Sets the JPEG quality level. The scale is 2 (best) to 31 (worst). A value of 8 is a good balance of quality and file size.
"<OUTPUT_FILE>": The path where the snapshot image will be saved.
