The `ffmpeg` component allows other Home Assistant components to process video and audio streams. This component supports all FFmpeg versions since 3.0.0; if you have an older version, please update.
|
|
|
|
<p class='note'>
|
|
You need the `ffmpeg` binary in your system path. On Debian 8 or Raspbian (Jessie) you can install it from [debian-backports](https://backports.debian.org/Instructions/). If you want [hardware acceleration](https://trac.ffmpeg.org/wiki/HWAccelIntro) support on a Raspberry Pi, you will need to build from source by yourself. Windows binaries are available on the [FFmpeg](http://www.ffmpeg.org/) website.
|
|
</p>
|
|
|
|
<p class='note'>
|
|
If you are using [Hass.io](/hassio/) then just move forward to the configuration as all requirements are already fulfilled.
|
|
</p>
|
|
|
|
To set it up, add the following information to your `configuration.yaml` file:
|
|
|
|
```yaml
|
|
ffmpeg:
|
|
```
|
|
|
|
Configuration variables:
|
|
|
|
- **ffmpeg_bin** (*Optional*): Default `ffmpeg`. The name or path to the `ffmpeg` binary.
|
|
- **run_test** (*Optional*): Default True. Check if `input` is usable by ffmpeg.
|
|
|
|
### {% linkable_title Raspbian Debian Jessie Lite Installations %}
|
|
To get the binary on Raspbian Debian Jessie Lite on a RPi you need to perform the following:
|
|
|
|
```bash
|
|
$ 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
|
|
```
|
|
|
|
### {% linkable_title Troubleshooting %}
|
|
|
|
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 `ffmpeg` out.
|
|
|
|
First, check that your stream is playable by `ffmpeg` outside of Home Assistant with (use option `-an` or `-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 `analyzeduration` and/or `probesize` options 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](https://www.ffmpeg.org/ffmpeg-formats.html#Description).
|
|
|
|
#### {% linkable_title USB cameras %}
|
|
|
|
For `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.
|
|
|
|
```bash
|
|
$ 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 `/dev/video1`:
|
|
|
|
```bash
|
|
$ ffmpeg -i /dev/video1 -codec:v libx264 -qp 0 lossless.mp4
|
|
[...]

|
