If it helps anyone, I’ve got a camera with onvif-support and solve the problem by adding the following to cron and use Home Assistant’s image file camera component. Of course, I had to install avconv first.
* * * * * cd /home/hass/.homeassistant/extraconfig/webcam && sudo /usr/bin/avconv -i rtsp://192.168.0.59:554/onvif1 -ss 0:0:2 -frames 1 no1.jpg
Could you write down a step by step instruction how to get it working? I tried to install avconv (ffmpeg) but couldn’t proceed.
I just ran
sudo apt-get install libav-tools and that was it.
I succeed installing avconv as you suggested and add the crontab -e (and replaced it with the IP address of my ONVIF cam. Then I add the HA local file component but still no show.
This error I appears:
The following platforms contain invalid configuration. group, camera.local_file error. Please check your configuration.
Is there an image file created? What if you download the file to disk and open it, can it be read?
If someone is still interesting:
You also shouldn’t forget to install ffmpeg on your system to make it works as it was mentioned by @rpitera
any updates?
camera:
- platform: ffmpeg
name: Cam
input: -rtsp_transport tcp -i rtsp://192.168.x.x:554/ch0.h264The general syntax is: rtsp://user:password@ip
Thanks I try
EDIT
Nope, I get

Ohh thanks wonder the extra f where it came from
Now is working, thanks!!
Is this taking a lot of resources?
What do you think is best, get the images refreshed every 10 seconds or so or the video?
ATTENTION!
I think that the camera is using streaming in background, is it so?
I can’t be 100% sure, but I think it was that component that consumed 3GB of my Data plan while in 4G with my smartphone, in few hours!!! ANd I was NOT using the app, almost all of the time must have been in background
I have Home Assistant in my smartphone, as icon in homepage created with Chrome browser).
Home-Assistant take all 10 sec a picture (frame) for Frontend. If you open a stream in Frontend, it start to stream (read, convert, ect) to frontend until you close the stream in frontend.
It don’t read the stream with ffmpeg, if you not look at it. So it need only resource on using time in frontend.
Mmhhhh, well I never had a consuption of 3GB of data on my smartphone in few hours!!. And I don’t look at movies or download stuff on the smartphone. I really think it was HA, for sure it was Chrome (is indicated in the stats for data usage)
I guess you just have a Chrome web-page not the entire Home assistant on your mobile phone 
If it is the case, I do not have the same experience as you have in huge consumption of data by Chrome webpage on my mobile phone, therefore, it must be something else on your phone.
