问题 This question already has answers here : Disable output buffering (16 answers) Using tee to get realtime print statements from python [duplicate] (1 answer) Closed 2 years ago . I got a python script running on startup on my raspberry pi (which works fine) where I want to append the output to an existing text file. I got this code in my /etc/rc.local file (I tried the same with cron, but there it doesn't even start the script for some reason). python3 /home/pi/script.py >> /home/pi/log.txt

For hardware decoding of H.264, VC-1, MPEG-2, MPEG-4. As a dependency you'll need the linux-raspberrypi-headers (Arch Linux)

问题 Up until recently, it has worked fine, but when I tried to use it today, it did not work properly.

问题 OBJECTIVE: I'm building a FPV robot, I want to control it with a with a webbrowser over a local wi-fi connection. I'm using a raspberry pi 3B+ with Raspbian Stretch. I built my own motor control and power regulator hat. After lots of research testing, I decided to use node.JS as http server and socket.io to provide a low latency bidirectional communication with my robot. This stack achieve about 7ms of latency. Picture of the robot PROBLEM: I need to stream low latency video from an USB
