Stream
The stream integration provides a way to proxy live streams through Open Peer Power. The integration currently only supports proxying H.264 source streams to the HLS format and requires at least FFmpeg >= 3.2.
Configuration
To enable this component, add the following lines to your configuration.yaml file:
# Example configuration.yaml entry
stream:
Services
Once loaded, the stream platform will expose services that can be called to perform various actions.
Service record
Make a .mp4 recording from a provided stream. While this service can be called directly, it is used internally by the camera.record service.
Both duration and lookback options are suggestions, but should be consistent per stream. The actual length of the recording may vary. It is suggested that you tweak these settings to fit your needs.
| Service data attribute | Optional | Description |
|---|---|---|
stream_source |
no | The input source for the stream, e.g., rtsp://my.stream.feed:554. |
filename |
no | The file name string. e.g., /tmp/my_stream.mp4. |
duration |
yes | Target recording length (in seconds). Default: 30 |
lookback |
yes | Target lookback period (in seconds) to include in addition to duration. Only available if there is currently an active HLS stream for stream_source. Default: 0 |
The path part of filename must be an entry in the whitelist_external_dirs in your openpeerpower: section of your configuration.yaml file.
For example, the following action in an automation would take a recording from rtsp://my.stream.feed:554 and save it to /config/www.
action:
service: camera.record
data:
entity_id: camera.quintal
filename: '/config/www/my_stream.mp4'
duration: 30
Troubleshooting
Some users on manual installs may see the following error in their logs after restarting:
2019-03-12 08:49:59 ERROR (SyncWorker_5) [openpeerpower.util.package] Unable to install package av==6.1.2: Command "/home/pi/open-peer-power/bin/python3 -u -c "import setuptools, tokenize;__file__='/tmp/pip-install-udfl2b3t/av/setup.py';f=getattr(tokenize, 'open', open)(__file__);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, __file__, 'exec'))" install --record /tmp/pip-record-ftn5zmh2/install-record.txt --single-version-externally-managed --compile --install-headers /home/pi/open-peer-power/include/site/python3.6/av" failed with error code 1 in /tmp/pip-install-udfl2b3t/av/

If you see this error you can solve it by running the following commands and restarting Open Peer Power (commands do not need to be ran as the openpeerpower user):
sudo apt-get install -y python-dev pkg-config libavformat-dev libavcodec-dev libavdevice-dev libavutil-dev libswscale-dev libavresample-dev libavfilter-dev
