Raspberry Pi 3B+ and Arducam Camera: Streaming Video and Audio to YouTube Live and Saving Locally with Debian Bullseye
In this article, we will guide you through the process of setting up a Raspberry Pi 3B+ with an Arducam camera to stream video and audio to YouTube Live, while also saving the stream locally. We will be using Debian Bullseye as our operating system.
Prerequisites
- Raspberry Pi 3B+
- Arducam camera module
- Debian Bullseye installed on the Raspberry Pi
- YouTube Live account
Setting up the Camera
First, you will need to install the video library for the camera. To do this, run the following command:
sudo apt-get install libcamera-apps
Next, you will need to configure the camera to output video at 800x600 resolution and 15 frames per second. To do this, edit the /boot/camera.conf file and add the following:
[camera]
driver = "imx477"
width = 800
height = 600
framerate = 15/1
Setting up the Audio
To get the audio, you will need to use the default audio source on the Raspberry Pi. To do this, run the following command:
arecord -f S16_LE -r 44100 -c 2 | ffmpeg -f s16le -ar 44100 -ac 2 -i - -c:a aac -b:a 128k -f flv rtmp://a.rtmp.youtube.com/live2/[stream-key]
Replace [stream-key] with your YouTube Live stream key.
Streaming to YouTube Live
Now that you have the camera and audio set up, you can start streaming to YouTube Live. To do this, run the following command:
ffmpeg -f v4l2 -i /dev/video0 -c:v h264_omx -b:v 1500k -g 30 -c:a aac -b:a 128k -f flv rtmp://a.rtmp.youtube.com/live2/[stream-key]
Replace [stream-key] with your YouTube Live stream key.
Saving the Stream Locally
To save the stream locally, you can use the following command:
ffmpeg -i rtmp://a.rtmp.youtube.com/live2/[stream-key] -c copy output.flv
Replace [stream-key] with your YouTube Live stream key. This will save the stream as an .flv file in the current directory.
- Install the video library for the camera:
sudo apt-get install libcamera-apps - Configure the camera to output video at 800x600 resolution and 15 frames per second: edit
/boot/camera.conf - Set up the audio:
arecord -f S16_LE -r 44100 -c 2 | ffmpeg -f s16le -ar 44100 -ac 2 -i - -c:a aac -b:a 128k -f flv rtmp://a.rtmp.youtube.com/live2/[stream-key] - Start streaming to YouTube Live:
ffmpeg -f v4l2 -i /dev/video0 -c:v h264_omx -b:v 1500k -g 30 -c:a aac -b:a 128k -f flv rtmp://a.rtmp.youtube.com/live2/[stream-key] - Save the stream locally:
ffmpeg -i rtmp://a.rtmp.youtube.com/live2/[stream-key] -c copy output.flv
