I am on windows 11 how do I get ffmpeg?

I am on windows 11 how do I get ffmpeg?

Option 1: Using winget (Built into Windows 11) - EASIEST

Open Command Prompt or PowerShell and run:

winget install ffmpeg

That's it! Restart your terminal and FFmpeg should be ready to use.

Option 2: Manual Installation

1. Download FFmpeg
   • Go to https://www.gyan.dev/ffmpeg/builds/
   • Download ffmpeg-release-essentials.zip
2. Extract the files
   • Extract the ZIP file to a folder like C:\ffmpeg
3. Add to PATH
   • Press Win + X and select "System"
   • Click "Advanced system settings" on the right
   • Click "Environment Variables"
   • Under "System variables", find and select "Path", then click "Edit"
   • Click "New" and add: C:\ffmpeg\bin
   • Click "OK" on all windows
4. Verify installation
   • Open a new Command Prompt or PowerShell
   • Type: ffmpeg -version

Option 3: Using Chocolatey (if you have it)

choco install ffmpeg

---

After installation, you can run the conversion commands I showed earlier. The winget method is the quickest if you just want to get started right away!

PEAK QUALITY 3D 180 IMMERSIVE VIDEO IN OCULUS GO AND GEAR VR

http://echeng.com/articles/peak-quality-3d-180-oculus/


Skybox VR, Virtual Desktop, Pixvana SPIN Player

Excellent article and I am collecting FFMPEG commands to try to understand how to do this sort of encoding.

ffmpeg -i "in.mov" -vf "scale=4096x2048:out_range=full:out_color_matrix=bt709" -c:v libx264 -preset fast -crf 18 -pix_fmt yuv420p -c:a copy -g 60 -movflags faststart "out.mp4"

Finally, I used Facebook Spatial Workstation’s FB360 Encoder to mux the video and audio, outputting in “FB360 Matroska” for Oculus headsets, and in “YouTube Video (with 1st order ambiX”) for other players like Pixvana SPIN Player.

ffmpeg stereo 3d VR180

Sorry, this is some raw notes and highlights here.


https://ffmpeg.org/ffmpeg-filters.html#stereo3d

‘hequirect’

Half equirectangular projection.

target_geometry

The target geometry of the output image/video. The following values are valid options:

‘rectilinear (default)’

‘fisheye’

‘panoramic’

‘equirectangular’

‘fisheye_orthographic’

‘fisheye_stereographic’

‘fisheye_equisolid’

‘fisheye_thoby’

‘dfisheye’

Dual fisheye.

‘fisheye’

Fisheye projection.

11.223.1 Examples

• Convert equirectangular video to cubemap with 3x2 layout and 1% padding using bicubic interpolation:

  ffmpeg -i input.mkv -vf v360=e:c3x2:cubic:out_pad=0.01 output.mkv
  

• Extract back view of Equi-Angular Cubemap:

  ffmpeg -i input.mkv -vf v360=eac:flat:yaw=180 output.mkv
  

• Convert transposed and horizontally flipped Equi-Angular Cubemap in side-by-side stereo format to equirectangular top-bottom stereo format:

  v360=eac:equirect:in_stereo=sbs:in_trans=1:ih_flip=1:out_stereo=tb
  

https://trac.ffmpeg.org/wiki/Stereoscopic

ffmpeg -i top-and-bottom.mov -vf stereo3d=abl:sbsl -c:a copy side-by-side.mov


ENCODING VR 360 AND 180 IMMERSIVE VIDEOS FOR OCULUS MEDIA STUDIO AND SIDELOADING INTO OCULUS QUEST AND GOhttps://echeng.com/articles/encoding-for-oculus-media-studio/

Exploring the Kanda QooCam 4K - pass1

I was hoping  to get live streaming off this camera, and it would appear if you have a 64 Bit android device their app can see a live video feed?

There is a Live option on the windows app that appears to do nothing.

 The USB doesn't show up as a video driver.


You can connect with the device over Wifi

To do this power on the device and wait for the power up tune to play.

one well timed (approx 1 second) power button push and it will beep and the blue wifi like will come on.

Scanning your wifi network SSID's, and you will see something like:

QOOCAM-06515

your camera id will vary based on the last 5 digits of the serial number.

password is : 12345678




From Linux, this command works but I was seeing many errors.

Best Oculus Quest Settings for 360 / VR180 Video Rendering in Premiere/F...

FROM : https://www.youtube.com/watch?v=iBGjn4rmFJU

What are the MAX resolutions and best render settings for 360° and VR180 content creators on the brand new Oculus Quest? This tutorial will give you a step by step guide on how to export your 360VR or 3D 180 videos and sideload them onto Oculus Quest for the best viewing experience with Adobe Premiere OR FFmpeg using both H.264 and H.265 (HEVC). Make sure to stay tuned and subscribe! My full review video for the HOTTEST headset of the year is coming out very soon!

⏰Timestamps for your viewing convenience:
2:57 - all MAX resolutions for Oculus Quest
4:23 - all my MAX 60fps resolutions (beyond Oculus recommendation)
6:12 - how to sideload videos onto Oculus Quest and the best way to play them
9:26 - Premiere rendering workflow with AfterCodecs
12:28 - FFmpeg workflow for BEST quality VR videos

LOW-COST VIDEO STREAMING WITH A WEBCAM AND RASPBERRY PI

http://videos.cctvcamerapros.com/raspberry-pi/ip-camera-raspberry-pi-youtube-live-video-streaming-server.html


Spoiler Alert, Basically they use the Raspberry Pi to connect to the CCTV IP camera over RTSP and then send a live stream up to youtube. Up, out though your firewall and NAT to youtube or any service that will accept RTMP.

Most of this is a good NOVICE GUIDE to setting up and configuring the Pi and buying a IP camera from them.

1. You can download the source code for the BASH script here.

#!/bin/bash

SERVICE="ffmpeg"
RTSP_URL="rtsp://192.168.0.119:554/video.pro1"
YOUTUBE_URL="rtmp://a.rtmp.youtube.com/live2"

COMMAND="sudo ffmpeg -f lavfi -i anullsrc -rtsp_transport tcp -i ${RTSP_URL} -tune zerolatency -vcodec libx264 -t 12:00:00 -pix_fmt + -c:v copy -c:a aac -strict experimental -f flv ${YOUTUBE_URL}/${YOUTUBE_KEY}"

if sudo /usr/bin/pgrep $SERVICE > /dev/null
then
        echo "${SERVICE} is already running."
