ffmpeg integration allows other Home Assistant integrations to process video and audio streams. This integration supports all FFmpeg versions since 3.0.0; if you have an older version, please update.
If you are running Home Assistant Core in a Python environment, you’ll need have the
ffmpeg binary in your system path.
On Debian 8 or Raspbian (Jessie) you can install it from debian-backports. If you want hardware acceleration support on a Raspberry Pi, you will need to build from source by yourself.
To set it up, add the following information to your
To get the binary on Raspbian Debian Jessie Lite on a Raspberry Pi you need to perform the following:
sudo echo "deb http://ftp.debian.org/debian jessie-backports main" >> /etc/apt/sources.list sudo apt-get update sudo apt-get -t jessie-backports install ffmpeg
We can use now following in the configuration:
ffmpeg: ffmpeg_bin: /usr/bin/ffmpeg
In most cases,
ffmpeg automatically detects all needed options to read a video or audio stream or file. But it is possible in rare cases that you will need to set options to help
First, check that your stream is playable by
ffmpeg outside of Home Assistant with (use option
-vn to disable video or audio stream):
ffmpeg -i INPUT -an -f null -
Now you should be able to see what is going wrong. The following list contains some common problems and solutions:
[rtsp @ ...] UDP timeout, retrying with TCP: You need to set an RTSP transport in the configuration with:
input: -rtsp_transport tcp -i INPUT
[rtsp @ ...] Could not find codec parameters for stream 0 (Video: ..., none): unspecified size: FFmpeg needs more data or time for autodetection (the default is 5 seconds). You can set the
probesizeoptions to experiment with giving FFmpeg more leeway. If you find the needed value, you can set it with:
input: -analyzeduration xy -probesize xy -i INPUT. More information about this can be found here.
INPUT a valid source is needed. A USB camera is an easy way to test your video setup. To get all available USB cameras connected to the system, e.g., use the v4l2 tools on a Linux machine.
$ v4l2-ctl --list-devices UVC Camera (046d:0825) (usb-0000:00:14.0-1): /dev/video1 Integrated Camera (usb-0000:00:14.0-10): /dev/video0
Record a test video with your USB device
