Raspberry Pi stream camera video using raspivid in rtsp protocol, view in Android using VLC app.

Work on Raspberry Pi 4B/8G running Raspberry Pi OS (32 bit), stream video from Camera Module to port 8000 in rtsp protocol, enter the command:

$ raspivid -o - -t 0 -n -w 800 -h 600 -fps 30| cvlc -vvv stream:///dev/stdin --sout '#rtp{sdp=rtsp://:8000/}' :demux=h264

where:

-w 800 : width=800

-h 600 : height=600

-fps 30 : 30 frame per second

8000 : the port to stream video

Open VLC App, Open Network Stream

rtsp://<Raspberry Pi IP>:8000/

e.g. rtsp://192.168.1.30:8000/

Raspberry Pi Python to set Brightness of Camera Module and preview

Example code of Python 2, run on Raspberry Pi, to control Camera Module, set Brightness and preview. Control Camera Module with picamera, and implement GUI with Tkinter. It's a Tkinter.Scale to set brightness.

Because the preview will be shown on main display, so I run the Python code remotely on Android tablet with Microsoft Remote Desktop app.


testBrightness.py

import picamera
from time import sleep
import Tkinter

def quit():
    camera.stop_preview()
    global tkTop
    tkTop.destroy()

def setBrightness(ev=None):
    global camera
    global tkScale
    camera.brightness = tkScale.get()

camera = picamera.PiCamera()
camera.start_preview()
camera.brightness = 50

tkTop = Tkinter.Tk()
tkTop.wm_title("Raspberry Pi Camera - Brightness")
tkTop.geometry('400x200')

tkButtonQuit = Tkinter.Button(
    tkTop, text="Quit", command=quit)
tkButtonQuit.pack()

tkScale = Tkinter.Scale(
    tkTop,
    from_=0, to=100,
    length=300,
    orient=Tkinter.HORIZONTAL,
    command=setBrightness)
tkScale
tkScale.set(50)
tkScale.pack(anchor=Tkinter.CENTER)

Tkinter.mainloop()

Login Raspberry Pi's VNC server from Android, with Remote Ripple

Android App Remote Ripple (RFB/VNC Viewer) is a free remote desktop client from the developers of TightVNC. View and control your desktop remotely, in real time, just as if you were sitting in front of remote PC, Mac or Unix system. It’s a VNC viewer so it can connect to any type of VNC server (including built-in screen sharing found in Mac OS X).

It can be used as VNC Viewer on Android devices to login Raspberry Pi remotely. In my test, TightVNC server is running on Raspberry Pi side, the App Remote Ripple run on HTC Flyer (Android 3.2.1).

Remote Ripple run on Android device, login Raspberry Pi

Install Remote Ripple (RFB/VNC Viewer) from Google Play.

- Click New Connection.

- Click More Options.

- Entaer Raspberry Pi's IP address in Host field, and tunnel number(in 590X form) in Port field, then click Connect.

- Enter VNC server Password, and click OK.
