| # This set of commands should allow you to stream video from your | |
| # Raspberry Pi Camera to Twitch and Youtube (and possibly other | |
| # RTMP endpoints) with decent quality and performance. | |
| # | |
| # You may need to install raspivid and/or ffmpeg to use this script. | |
| # | |
| # This was tested and built on Raspbian 9 installed using Noobs | |
| # ================================================================= | |
| # Set width and height of output video | |
| WIDTH=1920 | |
| HEIGHT=1080 | |
| # Set output framerate | |
| FRAMERATE=30 | |
| # Set keyframe spacing (must be double the framerate) | |
| KEYFRAME=60 | |
| # Set bitrate (Twitch recommends 3500000) | |
| BITRATE=3500000 | |
| # Set stream URL | |
| URL= | |
| # Set stream key | |
| KEY= | |

| # Full Documentation of Command Options | |
| # | |
| # +++ raspivid +++ | |
| # -n = no preview window | |
| # -t = time to capture (0 to disable, which allows streaming) | |
| # -w = video width | |
| # -h = video height | |
| # -fps = output framerate (max 30 for 1080p, 60 for 720p) | |
| # -b = bitrate | |
| # -g = keyframe rate (refresh period) | |
| # -o - = output to stdout (allows piping to ffmpeg) | |
| # | |
| # +++ ffmpeg +++ | |
| # -f lavfi = use lavfi filter (see note below) | |
| # -i anullsrc = grab blank input (see note below) | |
| # -c:a aac = set audio codec to aac | |
| # -r = output framerate (should match raspivid framerate) | |
| # -i - = read input from stdin (piped from ffmpeg) | |
| # -g = keyframe rate (refresh period) | |
| # -strict experimental = allow nonstandard things | |
| # -threads 4 = set number of encoding threads to 4 (# of cores) | |
| # -vcodec copy = use video as-is (do not re-encode video) | |
| # -map 0:a = use the audio from input 0 (see note below) | |
| # -map 1:v = use the video from input 1 (raspivid) | |
| # -b:v = bitrate | |
| # -preset ultrafast = use the ultrafast encoding preset | |
| # -f flv = set output format to flv for streaming | |
| # "${URL}/{KEY}" = specify RTMP URL as output for stream | |
| # | |
| # ** NOTE ** | |
| # According to some information online, YouTube will reject a live | |
| # stream without an audio channel. So, in the ffmpeg command above | |
| # a blank audio channel is included. It was not required for Twitch | |
| # in my testing. | |

Hey, this script works great! Like the comment above, I'm interested in automatically starting the script with a cron job or similar. I can't seem to make it work, however. I have the script set as an executable with chmod +x, and it works well when I call it from the terminal, but I can't seem to run it automatically via cron or rc.local. Any advice you have is appreciated!
Hello! First, Thanks for this script, it works really well!
@TaylorHokanson, Here is what I used to run this script when the pi starting:
In /etc/systemd/system/ I have create an new file (with sudo): launchTwitchLive.service
[Unit]
Description=Launch Twitch Live
After=network.target
[Service]
ExecStart=/bin/bash -u picam-stream.sh
WorkingDirectory=/home/pi/Live
StandardOutput=inherit
StandardError=inherit
Restart=always
User=pi
[Install]
WantedBy=multi-user.target
(The live script is in /home/pi/Live/picam-stream.sh)
And after, you need to register this service for pi start with: sudo systemctl enable launchTwitchLive.service
You can restart now ;)
If you need to stop after start : sudo systemctl stop launchTwitchLive.service
If you need to start after stop : sudo systemctl stop launchTwitchLive.service
And the doc for more informations: https://www.raspberrypi.org/documentation/linux/usage/systemd.md
Good live!
Edit: I even disabled the desktop on startup to consume less resources, it works great :)
Thanks so much for the detailed answer. When my project goes live I'll be sure to note your help and send you a link.
Thanks everyone for the input! This is fantastic! I'm glad folks are finding this useful.
have you ever tried adding an audio stream from a micro usb adapter like this?

I am trying to achieve the same ...
I got it working with a sound card, but you might need to recompile FFmpeg. I also added audio-video syncing and camera settings:
`#!/bin/bash
# Set width and height of output video
WIDTH=1920
HEIGHT=1080
# Set output framerate
FRAMERATE=30
#Set Rotation
ROTATION=0
# Set keyframe spacing (must be double the framerate)
KEYFRAME=60
# Set bitrate (Twitch recommends 3500000)
BITRATE=3500000
# Camera Settings (includes commands)
SATURATION=25 #sa
SHARPNESS= #sh
CONTRAST= #co
BRIGHTNESS= #br
AWB= #awb
ISO= #iso
SHUTTERSPEED= #ss
EXPOSURE= #ex
EV=0 #ev
ANTIFLICKER= #fli
IMAGEEFFECT= #ifx
# Set video offset
OFFSET=0.5
# Set Audio input (check using "arecord -l")
INPUT=plughw:2,0
# Set stream URL
URL=
# Set stream key
KEY=
# Command
raspivid -o - -t 0 -w $WIDTH -h $HEIGHT -fps $FRAMERATE -b $BITRATE -rot $ROTATION -g $KEYFRAME -sa $SATURATION -awb $AWB -ev $EV -f | /home/pi/ffmpeg/ffmpeg -use_wallclock_as_timestamps 1 -thread_queue_size 10240 -f h264 -r 30 -i - -itsoffset $OFFSET -f alsa -thread_queue_size 10240 -ac 2 -i $INPUT -vcodec copy -acodec aac -ac 2 -ar 44100 -ab 192k -f flv "${URL}/${KEY}"
`
That looks awesome! Thanks for the update. I'll have to try it sometime.
thank you, it's working like a charm.
Just want to share some appreciations to @russfeld for the script and @florian-luce for the systemd implementation. Works like a charm! 🙏❤
This script works brilliantly. A tip if you have the NOIR camera: Add -awb greyworld to the raspivid command so that the output doesn't look pink.
I get the following warnings :
[h264 @ 0x212b090] Thread message queue blocking; consider raising the thread_queue_size option (current value: 8)
[flv @ 0x21dcc40] Timestamps are unset in a packet for stream 1. This is deprecated and will stop working in the future. Fix your code to set the timestamps properly
Thanks for this amazing script, i was checking on the how to add audio to it. I saw the comments about adding an input using a usb soundcard input. In my case I just needed to add a background music to the stream with no need of sync with the video, so my plan is to use prerecorded mp3 audio file, here is how I modified the command for that purpose:
raspivid -n -t 0 -w $WIDTH -h $HEIGHT -fps $FRAMERATE -b $BITRATE -g $KEYFRAME -o - | ffmpeg -i audio-file.mp3 -c:a aac -r $FRAMERATE -i - -g $KEYFRAME -strict experimental -threads 4 -vcodec copy -map 0:a -map 1:v -b:v $BITRATE -preset ultrafast -f flv "${URL}/${KEY}"
Hi first for making this script its been a huge help, I have a problem since raspivid is no longer working, I have tried to modify it by changing it to: libcamera-vid -n -t 0 --width $WIDTH --height $HEIGHT --frames $FRAMERATE -g $KEYFRAME -b $BITRATE -o -| ffmpeg but in twitch, I only get a blank screen and 0kbps bitrate. Any idea of what can I do to fix this?
UPDATE:
I've made an updated tool that works with libcamera and with more additions. Here it is: https://github.com/diegozalez/RaspyStream
This is brilliant, thank you so much for this, works a treat!
This is brilliant, thank you so much for this, works a treat!
Thanks a lot!!!! it means to me very much !!!!
Many thanks for this. I am using a raspberry pi 3B with the raspicam v2 to stream live video, and I have tried many combinations including raspivid, ffmpeg, ncat, and uv4l, and this is the best I have found by far. I am able to stream 30fps at 1920x1080 to a Twitch account. None of the other solutions provided this fps. Having the script will be particularly helpful so I can include this in a cron job. Thanks again for providing this solution.
