The stream integration provides a way to proxy live streams through Home Assistant. Most users should not need to configure anything or interface with the component directly since it is an internal component used by the camera integration.


The stream integration is automatically loaded by default_config and enabled by the camera platforms that support it. If default_config is used, no separate configuration.yaml entry is necessary. However, there are some extra options you can configure.

Configuration Variables

ll_hls boolean (Optional, default: true)

Allows disabling Low Latency HLS (LL-HLS)

segment_duration float (Optional, default: 6)

The duration of each HLS segment, in seconds (between 2 and 10)

part_duration float (Optional, default: 1)

The duration of each part within a segment, in seconds (between 0.2 and 1.5)

LL-HLS - Low Latency HLS

LL-HLS reduces the start time and delay for a stream, but it has strict timing and network requirements and opens additional browser connections. To avoid running into browser limits it is strongly recommended to use an HTTP/2 proxy (e.g., NGINX or haproxy) to take advantage of request pipelining. LL-HLS is enabled by default, but when not using HTTP/2, the Home Assistant frontend will revert back to regular HLS if too many streams are open.

You can further adjust LL-HLS settings in configuration.yaml as it may perform better or worse with different values depending on your network setup, cameras, or whether or not they are local or cloud.

Example configuration:

# Example LL-HLS configuration.yaml entry.
  ll_hls: true
  part_duration: 0.75
  segment_duration: 6

Technical Details

The integration currently supports proxying H.264 and H.265 source streams to the HLS protocol and requires at least FFmpeg >= 4. Note that H.265 support is limited to Safari, iOS, and Android. The stream integration also provides limited support for audio. PCM codecs (e.g. G.711/G.723/G.726/G.729) are not supported. ADTS AAC audio is also currently not supported. Most other AAC and MP3 encoded audio should work.


Users on manual installs with FFmpeg < 4 may see an error similar to:

2020-04-28 13:35:43 ERROR (SyncWorker_5) [homeassistant.util.package] Unable to install package av==7.0.1: ERROR: Command errored out with exit status 1:

You can solve this by running the following steps to update FFmpeg >= 4:

sudo add-apt-repository ppa:jonathonf/ffmpeg-4
sudo apt upgrade
