open-telemetry-kit 0.1.1

Open source package for extracting and parsing telemetry associated with video streams and converting to common formats.

Open Telemetry Kit

The Open Telemetry Kit (OTK) is an open source package for extracting and parsing telemetry associated with video streams and converting to common formats. It comes out of a need for a singular API that can be used for multiple different video telemetry formats.

Telemetry that can be parsed includes: GPS, time, camera information, speed

Features:

• Automatically detect telemetry format
• Manipulate telemetry with ease
• Write telemetry to a new format

Getting Started

Prerequisites

Python version: >=3.6

ffmpeg and ffprobe.

On Debian systems these can be installed with:

$ sudo apt install ffmpeg

dateutil

On Debian systems this can be installed with:

$ pip install python-dateutil

Installation

$ pip install open-telemetry-kit

Importing

The OTK package can be imported into your project with:

import open_telemetry_kit as otk

Quick Start

Download quickstart.py and DJI_telemetry.srt from the Open Telemetry Kit git page.

Execute the script via:

$ python3 quickstart.py [/path/to/source/DJI_telemetry.json] [/path/to/save/destination.json]

The script accepts a standalone .csv or .srt or a video file with an embedded .srt. It will read in the data, convert it to JSON, and write it to the provided destination.

Note: this process will create a metadata.json file in the same path as the source file. If the telemetry is embedded it will also extract the data into [video_name].json

Current Functionality

Input Formats

The OTK currently supports the following forms of telemetry:

• .csv files
• .srt files
• Any video file with embedded telemetry encoded as a .srt (e.g. video taken with some DJI drone models)

Output Formats

• JSON

Future Releases

Planned expansions and updates for the OTK include:

Input Formats

• .kml
• .gpx
• KLV/MISB embedded data

Output Formats

• geoJSON

Other

• Logging
• Error checking
• Unit Tests
