If you are not sure try first with NVENC and if is failing use the generic x264 encoder. On other case you will use the more generic x264 encoder of ffmpeg. It is a feature that performs video encoding on your graphic card, offloading this compute-intensive task from the CPU. If you own a NVidia Graphic Card then you can use the Nvidia NVENC.
Open a windows command and stitch live stream with a first command.įor each scripts I give two options depending on your Graphic Card.

I provide four sets to match different situation : The build-in map filter of ffmpeg needs two files to map each pixel from video source to target video. Using remap we can emulate a equirectangular projection using a pre-calculated map at a much faster rate. The principle of ffmpeg mapping is to use original pixels from video source and map them at specific positions into video output. To achieve the same in real-time we will use a trick, the remap function of ffmpeg. As you already stitch video with Xiaomi Application you know this operation consumes a lot of CPU power. #Mi sphere stitching full
You will probably notice the live stream of camera is the dual fish eyes and is not the full resolution of camera but is limited to 720p/60FPS.īefore streaming to YouTube one needs to stitch the dual fish eyes into equirectangular projection in real-time.
By using VLC and opening a network source menu Media / Open Network Stream (Ctrl+N) type this address. Once you are connected you can check the live stream of the camera is available. Power on the camera, enable WIFI on your PC, browse through WIFI connections and search for a SSID starting with MIXJ- it is your Xiaomi Mijia Mi Sphere Camera. Be aware the camera IP address is fixed with 192.168.42.1 mask 255.255.255.0 thus if your network already use the same address space 192.168.42.x you won’t be able to connect and you will need to change your router address. #Mi sphere stitching Pc

Before going further one condition is absolutely required for this hack to work: you will need two connections at same time, a wireless connection to get your camera stream input and a wired connection to your router to stream the ouput to Youtube. Though I tried to make it understandable to everyone, you will need coffee or tea if you are not familiar with typing cryptic commands. 
This tutorial is for Windows 10, although it can work on a different OS but you will need to adapt yourself.
I won’t say it is perfect, but it works on some conditions. Here are some informations to live stream your Xiaomi Mijia Mi Sphere or Madventure360 camera on YouTube, Facebook and Periscope.
