What's inside teslamotors-dashcam

  1. Extract SEI metadata using sei_extractor.py

    master
    For programmatic or command-line access to metadata, use the sei_extractor.py Python script. This tool extracts SEI data (such as vehicle speed, steering wheel angle, and self-driving state) from supported MP4 files.

  2. View Dashcam metadata with the SEI Explorer

    master

    The easiest way to view Tesla Dashcam MP4 clips alongside their associated SEI (Supplemental Enhancement Information) metadata is to use the web-based SEI Explorer.

    1. Navigate to the online SEI Explorer.
    2. Drag and drop your MP4 file into the browser.

    The tool processes files entirely within your browser; your video files are never uploaded to a server.

  3. Requirements for SEI metadata presence

    master

    Not all Tesla dashcam clips contain SEI metadata. To ensure your clips contain the data required for these tools, they must meet the following criteria:

    • Firmware Version: Recorded on Tesla firmware 2025.44.25 or later.
    • Hardware: Vehicle must have Hardware 3 (HW3) or above.
    • Vehicle State: The vehicle should not be parked (SEI data may not be present if the car is parked).
