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.

Configuration

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. If default_config is not used, the stream integration can be activated with the entry below:

# Example configuration.yaml entry. There are no additional options.
stream:

LL-HLS

There is the option to enable LL-HLS for lower latency. Please note that LL-HLS has strict timing and network requirements that can be hard to meet, so this option may not work on all setups. As HTTP/2 is required by the LL-HLS specification, the use of an HTTP/2 enabled reverse proxy is strongly recommended. To enable LL-HLS, add the following to your configuration.yaml:

# Example LL-HLS configuration.yaml entry.
stream:
  ll_hls: true
  part_duration: 0.75  # Range of 0.2 to 1.5
  segment_duration: 6  # Range of 2 to 10

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.

Troubleshooting

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:

         cwd: /tmp/pip-install-twd7glz2/av/

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

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