How the New Coronavirus Spreads and Progresses

The number of Covid-19 cases continues to rise, surpassing 4 million as this coronavirus tracker shows.

The total number of cases is now at 4,290,410 with 2,458,682 cases still active. According to quarantine.country, 45 million people have been tested for the Coronavirus, at the time of writing this article, and once more tests are conducted the novel coronavirus infection numbers could rise.

The US continues to have the biggest share of those, recording 18.502 new cases yesterday. The mortality rate in all the countries is trending downwards however, as lockdowns are eased in some capacity across the world, some fear we could see the numbers climb back up.

@hoosier with version 1.201+ you have feedback about the current bitrate and connection quality, check the status indicator**; red = something not optimal (most likely slow Wi-Fi or 4G LTE). As a backup it’s always a good idea to save your broadcast (Record to iPhone)

@acpregion5 can you embed a sample video please, with iOS you can record the screen while streaming.

Dahua IPC-HFW4300S (HD 1080p PoE IP Camera)

1. Prepare, you will need:

• a router (cable modem, or other similar device) with at least one free LAN port (Internet)
• Dahua IPC-HFW4300S IP Camera
• PoE Injector or PoE Switch or PoE Router (to power the camera)
• Two RJ45 Cat5e Ethernet Cables Step

2. Connect:

• 1. connect the first RJ45 cable to your Internet connection (ex. Router LAN port)
• 1.1 connect the other end to the PoE injector (or PoE Switch). If your router has a PoE LAN port, you can skip this step
• 2. connect the second RJ45 cable to the PoE injector output (Power+Data OUT)
• 2.1 connect the other end to the Dahua IPC-HFW4300S IP Camera

3. Access Setup: the Dahua cameras are preset with fixed IP addresses: 192.168.1.108 and they will not automatically get an IP address from the DHCP server (e.g. the router). You will need to do is temporarily set your Mac to use an IP on the same subnet as the camera (for example, 192.168.1.109 - the first three numbers have to be the same and the fourth different), and then you will be able to access the camera at 192.168.1.108 using a web browser. You then set the camera to use an IP address on the same subnet as your network, reset your Mac's IP settings, and then the camera is visible to your network. This is described in our setup instructions for network cameras. While the camera is on a different subnet, you will be able to detect it via its Bonjour address, however all attempts at accessing it will fail.

• 1. fire up BonjourBrowser and find the IP and Port of the camera
• 1.1 the default IP is 192.168.1.108, default user name and password: admin/admin, the port is 80
• 2. to create port forwarding on your router for the IP and Port probably you will have to reserve a local IP for the camera so
• 3. create a DHCP reservation for the camera and after done, reboot your router and camera to make sure the camera has the reserve IP address ex. 10.0.1.23 4. create a port forwarding with the default port (80) and the IP address above
• 4. access the address with a web browser and change the IP address and Port after your preference, the default admin pass is admin/12345

Hikvision DS-2CD2032-I (HD 1080p PoE IP Camera)

1. Prepare, you will need:

• router (cable modem, or other similar device) with at least one free LAN port (Internet)
• Hikvision DS-2CD2032-I IP Camera
• PoE Injector or PoE Switch or PoE Router (to power the camera)
• Two RJ45 Cat5e Ethernet Cables Step

2. Connect:

• 1. connect the first RJ45 cable to your Internet connection (ex. Router LAN port)
• 1.1 connect the other end to the PoE injector (or PoE Switch). If your router has a PoE LAN port, you can skip this step
• 2. connect the second RJ45 cable to the PoE injector output (Power+Data OUT)
• 2.1 connect the other end to the Hikvision DS-2CD2032-I IP Camera Step

3. Access Setup:

• 1. fire up BonjourBrowser and find the IP and Port of the camera
• 2. create port forwarding on your router for the IP and Port
• 3. access the address with a web browser and change the IP address and Port after your preference, the default admin pass is admin/12345 Step
• 3.1 if Step 3. does not work:
• • 1. download software from Hikvision
• • 2. access camera and set your IP and Port (default admin pass is admin/12345)
• • 3. create port forwarding

HUACAM HCV712 (HD 720p PoE IP Camera)

1. Prepare, you will need:

• router (cable modem, or other similar device) with at least one free LAN port (Internet)
• HUACAM HCV712 IP Camera
• PoE Injector or PoE Switch or PoE Router (to power the camera)
• Two RJ45 Cat5e Ethernet Cables Step

2. Connect:

• 1. connect the first RJ45 cable to your Internet connection (ex. Router LAN port)
• 1.1 connect the other end to the PoE injector (or PoE Switch). If your router has a PoE LAN port, you can skip this step
• 2. connect the second RJ45 cable to the PoE injector output (Power+Data OUT)
• 2.1 connect the other end to the HUACAM HCV712 IP Camera Step

3. Access Setup:

• 1. Open Terminal and type in: arp -na
• 2. try to locate the IP address and when found, access it via any web browser. Ex. 10.0.1.4
• 3. Click on Configuration (user and pass is admin/admin)

Live Streaming with your GoPro

How to stream live from GoPro HERO and other GoPro models

You'll need a GoPro HERO camera and a MAC or PC for transcoding the live stream with both wired and wireless connections (read below why)

For sending a live video stream from your GoPro HERO to Facebook Live, YouTube Live or any other media server, you will need internet connection. Since your computer's Wi-Fi will be used for connecting to your GoPro camera, a second (most likely) wired Ethernet connection is required that will provide the internet access. Note: this is only needed if you are using the GoPro's live video stream, meant for the GoPro App video preview. GoPro HERO3 - HERO4+ cameras produce HLS streams which are used by control apps and monitors. It's possible to take this stream and rebroadcast over RTMP. This is a low-quality stream that can be easily accessed via WiFi, when the camera is in App & RC mode. There are better methods for obtaining a HD livestream using a HDMI cable and an external device with http://cameleon.live.

GoPro Live Stream with VLC (VideoLAN)

Get HLS stream from your GoPro, please view images below and follow these quick steps:

• On your GoPro camera enable Wi-Fi for GoPro App (Not for Remote Control)
• Connect to your GoPro's Wi-Fi network with your computer (Note: your internet connection will probably stop)
• Open System Preferences > Network > Advanced... and select the TCP/IP tab. Take note of the "Router:" IP address, more than likely 10.5.5.9
• Open your browser and access the above-mentioned IP address on port 8080 e.g. http://10.5.5.9:8080

Test: if you did everything as demoed trough the screenshots above AND you're connected to your GoPro's Wi-Fi, this link should work: http://10.5.5.9:8080

• Download VLC from videolan.org - 2.2.4 Weatherwax (Intel 64bit) earlier/later versions should also work
• Run VLC from command line, example with parameters:

GoPro HERO4 and GoPro HERO4 Session

vlc udp://@:8554 --sout="#transcode{vcodec=h264}:rtp{dst=127.0.0.1,port=4444,sdp=rtsp://0.0.0.0:8080/live.sdp}" --verbose=3 --logmode=text --file-logging

• Accessing the GoPro live stream is also available from within the VLC app by going to File > Open Network... and entering 'udp://@:8554' into the URL field (no logs on screen)

GoPro HERO3 and GoPro HERO3+

vlc http://10.5.5.9:8080/live/amba.m3u8 --sout="#transcode{vcodec=h264}:rtp{dst=127.0.0.1,port=4444,sdp=rtsp://0.0.0.0:8080/live.sdp}" --verbose=3 --logmode=text --file-logging

• replace the IP address of your GoPro camera

Error: Running VLC from the terminal gives error: -bash: vlc: command not found (read section below)

VLC terminal error: -bash: vlc: command not found

You can run VLC on Mac OS X using terminal (/Applications/Utilities/Terminal) with the following command:

/Applications/VLC.app/Contents/MacOS/VLC http://10.5.5.9:8080/live/amba.m3u8 --sout="#transcode{vcodec=h264}:rtp{dst=127.0.0.1,port=4444,sdp=rtsp://0.0.0.0:8080/live.sdp}" --verbose=3 --logmode=text --file-logging

You can also set an alias to just vlc with the following command:

alias vlc='/Applications/VLC.app/Contents/MacOS/VLC'

• this can be helpful to add this command to your shell setup file (this option can also be activated from the "VLC" menu).

Note:

• You may need to modify the VLC media player configuration to MPEG streaming by changing the VLC stream transport protocol (read section below). This will open a RTSP port 8080 on your computer and if your firewall is allowing traffic on port 8080, you're ready to go. Your RTSP path will be rtsp://{YOUR_COMPUTERS_IP_ADDRESS}:8080/live.sdp (copy this URL)
• Command line examples, VLC Streaming Wizard

Switching VLC from HTTP streaming to RTP/RTSP streaming

• Open VLC > Preferences..., select Input / Codecs tab and check the box next to "Use RTP over RTSP (TCP)". Save.

GoPro live stream won't play?

Let's try something else, Download FFmpeg (here) or follow instructions for Installing FFmpeg for macOS / Windows (read section below)

Install FFmpeg for macOS

• The easiest way to install FFmpeg on macOS (Mac OS X ) is using Homebrew and Xcode Command Line Tools. Install Xcode from the Mac App Store (update to the latest version if necessary). Xcode may prompt you to install command line developer tools or you can install it by typing the following command into the terminal:

xcode-select --install

• Installing Homebrew is quite simple as well, type the following command into the terminal:

/usr/bin/ruby -e "$(curl -fsSL >>https://raw.githubusercontent.com/Homebrew/install/master/install)"

* after successful installation you should execute: '$ brew doctor' -to check if your Homebrew >>installation was successful

• Install FFmpeg - install by typing the following command into the terminal:

brew install ffmpeg --with-ffplay

GoPro Live Stream with FFmpeg

• Connect to your GoPro via Wi-Fi
• Run FFmpeg from command line, with parameters:

ffplay -an -fflags nobuffer -f:v mpegts -probesize 8192 rtp://10.5.5.9:8554

• Still no luck? Make sure your Mac is connected to your GoPro's Wi-Fi network (check your Mac's Wi-Fi connection, it should be connected to your GoPro and not your router/internet). Try (re)starting GoPro real-time A/V stream using LTP by sending this command via your browser:

http://10.5.5.9/gp/gpControl/execute?p1=gpStream&c1=restart

• Check out other GoPro Hero4 Remote tools @ <cite title="3v1n0's gist, Marco Trevisan">3v1n0's gist</cite> | for GoPro Cameras with older firmware, use command: http://10.5.5.9/gp/gpExec?p1=gpStreamA9&c1=restart
• You may want to read How to livestream from a GoPro HERO4 reddit post for latest info and comments

Note: GoPro live stream will stop unless a "keep alive packet" is maintained (power-saving), run a script e.g.: hero4-udp-keep-alive-send.py in parallel with FFplay to keep the camera live
Test: GoPro live stream should appear in your FFplay media player. Remove the '-an' flag to receive audio from your GoPro

Go Live

• Open your Live Streaming App and paste the RTSP path by following the instructions below. Pro builds of Cameleon Live should detect GoPro HERO cameras automatically, there is no need for the above nor pasting the RTSP path(s).
