• Step1. Turn on Tello and connect your computer device to Tello via wifi.

• Step2. Open project folder in terminal. Run:

  python tello_ros.py(第一次可能会报错，再运行一次)
  

Wrapper class to interact with Tello drone. Modified from https://github.com/microlinux/tello

The object starts 3 threads:

1. thread for receiving command response from Tello 端口8888
2. thread for receiving video stream 端口11111
3. thread for receiving state 端口8890

You can use read_frame() to read the last frame from Tello camera, and pause the video by setting video_freeze(is_freeze=True). You can use read_state() to read the state of Tello**.

From https://github.com/DaWelter/h264decoder.

A c++ based class that decodes raw h264 data. This module interacts with python language via python-libboost library, and its decoding functionality is based on ffmpeg library.

After compilation, a libh264decoder.so or libh264decoder.pyd file will be placed in the working directory so that the main python file can reference it.

If you have to compile it from source,with Linux or Mac,you can:
