gPhoto2-Liveview-Python

Demo of gPhoto2 live view in python. Adapted from aqiank/gphoto2-liveview-example

Requirements

1. gPhoto2
2. Python 3
3. tkinter
4. pillow
5. DSLR Camera

Use

1. Download liveview.py and navigate to its directory
2. Plug in a USB connector from your camera to your computer
3. run gphoto2 --capture-movie --stdout | python liveview.py

Explanation

gphoto2 --capture-movie --stdout will spit out a byte stream of jpegs, where each jpeg is delimited by a start code \xff\xd8 and a stop code \xff\xd9. All there is to creating a frame of the liveview is reading what's in between those codes and displaying it as a jpeg to the screen. Do that repeatedly and you have a liveview. liveview.py does the reading and displaying in two separate threads to increase speed, but this might be unnecessary depending on your camera and computer.
