Home Assistant release with the issue:

0.73.1

Last working Home Assistant release (if known):
N/A

Operating environment (Hass.io/Docker/Windows/etc.):

Ubuntu Bionic. Using virtualenv
Running on old x86 Intel Celeron 900Mhz with 1Gb of RAM and 8Gb of HD

Also when using HASSIO on Rpi 3B+

Component/platform:

ffmpeg

Description of problem:
Keep getting timeout on reading image. Network related has been ruled out.

Due to the old hardware I'm using HASS on, the timeout value of 15 sec for ffmpeg getting still images is not enough.
Changing the timeout locally to 20 sec stabilizes the system. Better would be to have it as a configuration setting for the ffmpeg component.

Problem-relevant configuration.yaml entries and (fill out even if it seems unimportant):

camera:
  - platform: ffmpeg
    name: Entrance
    input: -rtsp_transport tcp -i rtsp://10.0.0.98:8554/unicast

Traceback (if applicable):

2018-06-24 21:41:58 WARNING (MainThread) [haffmpeg.tools] Timeout reading image.
2018-06-24 21:42:00 ERROR (MainThread) [homeassistant.core] Timer got out of sync. Resetting

I'm also having problems with ffmpeg. Can you discribe where you changed timeout locally, then I can try that too and see if it's the same problem.

This is also a problem for me

I'm hesitant to think my problems are related to performance since I'm running on an Intel nuc.

I'm also hesitant. My instance is running on a RPi 3.

After upgrading from an old version (0.73.2) to the latest version (0.79.1), all my camera's give the error:
[haffmpeg.tools] Timeout reading image.

So, something has changed, and I hope it will be fixed soon!

I'm experiencing the same issue(0.79.3). For me it seems to be working and then crashes after a couple of min with error "Timeout reading image."

Using 0.80.1 I get this error in the log while the camera component is setup:

/usr/src/app/homeassistant/components/camera/ffmpeg.py:35: RuntimeWarning: coroutine 'FFmpegManager.async_run_test' was never awaited

if not hass.data[DATA_FFMPEG].async_run_test(config.get(CONF_INPUT)):

How to change the timeout? I've the same errors.

i have a Xiaomi Aqara "hub&cam"/"cam&hub", and also get this "timeout reading image" in my log many times (sometimes 6 per minute, than a pauze for 1 or >30 minutes etc).

Not sure whether it is related to the camera going into sleep mode; just did a short test by getting the cam out of sleep, rebooting the Rpi, and 25min in, not a single error about reading the image...

Just found https://www.programcreek.com/python/example/104604/async_timeout.timeout, see example 39 ... i'm not a programmer, but i think when some checks fail, it leads to the error written to the logs. Maybe there are too many situations not handled, leading to that error being written, and we can ignore it in many cases? @pvizeli might know more.

Same issues on 0.84.6
I had zero problems with RPI3b+ and Xiaomi Dafang camera and suddenly I started getting:
Timeout reading image.

I restarted the HASS and the camera with no luck. When streaming the RTSP via VLC I have very minimal lag (miliseconds) so I am not sure what happened.

Same issue over here, camera worked for about a week or 2 without any problems and today it started to give me these errors, https://community.home-assistant.io/t/out-of-the-blue-issues-with-camera-snapshot-service/90526

@vout this does bot seem related. The error here is specifically with Xiaomi Dafang cameras.
According to your write up your issue seems to be specifci to hikvision component. I suggest you open another issue.

@tsvi No it seems like exactly the same error, an timeout issue. So probably it isn't an Xiaomy Dafang issue only but an general rtsp stream issue.

The "setup" you have in your opening post is the same i have,

- platform: ffmpeg
  name: IP camera oprit
  input: !secret ip_camera_oprit_stream
  extra_arguments: '-q:v 1 -r 25 -vf "scale=640:360"'

Where !secret ip_camera_oprit_stream is just an regular rtsp stream

I did some extensive debugging.
First of all try running ffmpeg on the command line as follows:
time ffmpeg [input arguments] -an -frames:v 1 -y -c:v mjpeg -loglevel verbose test.jpg

I discovered that this was taking 5+ seconds, because it was trying to detect the sound stream which was badly configured.
By disabling the sound from the camera I brought it down to 1 sec.
Also the MQTT server is a bit sluggish on the camera. Once I stopped using MQTT for sending commands I got a reasonable performance.

Seeing the same error using a Yi home cam. I'm migrating HA to new hardware and this config is working on the old installation (RPI Zero)

  - platform: yi
    name: 'Front Yard'
    host: '10.0.0.13'
    password: !secret FrontCamPass
    path: /tmp/sd/record
    ffmpeg_arguments: '-vf scale=640:480'

Is this still an issue you are experiencing? Can you please try upgrading to the latest version of Home Assistant (0.90) and report back if this is still a problem? Thanks!

This is still an issue for me on quite powerful hass running as virtual machine

It worked several times, but now even after reboot I constantly getting timeouts.
