Yi component "Image not available"

cexshun · December 24, 2017, 4:24am

I’m trying to get my Yi Dome 1080p camera to work. The hack-v3 is working fine. App is working and video is being recorded. However, in HASS, I’m getting “Image not available”.

Configuration:

camera:
  - platform: yi
    name: Living Room
    host: 192.168.1.152
    password: !secret yi_cam
    ffmpeg_bin: /usr/bin/ffmpeg

Put the log in debug for component.camera and only see this in the log.

2017-12-23 22:16:02 DEBUG (MainThread) [homeassistant.components.camera.yi] Received configuration: OrderedDict([(‘platform’, ‘yi’), (‘name’, ‘Living Room’), (‘host’, ‘192.168.1.152’), (‘password’, ‘redacted’), (‘ffmpeg_bin’, ‘/usr/bin/ffmpeg’), (‘username’, ‘root’), (‘port’, 21), (‘path’, ‘/tmp/sd/record’)])

If I ftp to that directory, I see the following:

/tmp/sd/record # ls -al

The YMD folders all have the mp4 in them.

Put some more work into it this morning. Still the same problem. When I call camera.snapshot, the file is created correctly in /home/homeassistant/.homeassistant/snaps/filename.jpg". However, the file created has 0 length and is empty. Debug logs:

More info. Seems the system quietly explodes if there is an & in the password for the camera. Changed the password and removed the random characters. FTP works now, but getting this when attempting to process the command manually:

ffmpeg -i ftp://root:[redacted]@192.168.1.152:21/tmp/sd/record/2017Y12M24D17H/47M37S.mp4 -an -frames:v 1 -c:v mjpeg -f image2pipe -

Sheesh. Finally got it. To get it to work, on the camera, I had to create a symbolic link in the root home directory to /tmp. Since the files are stored in the root of the camera in /tmp, HASS was accessing the file in /root/tmp. Created the link with

ln -s /tmp tmp

It works now! Little undocumented bug for the Yi setup there. I hope the symbolic link on the Yi filesystem survives a reboot.

Notvans · December 29, 2017, 8:03am

You fix worked thanks a lot. The only problem is we have to sym link every time the camera reboots.

cexshun · December 29, 2017, 8:15am

I’ve tested multiple times and have not had to recreate the symlink. For me, it’s been permanent.

LaFed · January 6, 2018, 3:57pm

@cexshun wow you are my hero… have been trying to get it to work for the past 2 days… thanks!!

fgorbat · January 6, 2018, 4:08pm

Thank you! It solved my problem!

ainen · January 11, 2018, 9:34pm

This worked perfectly for me. Maybe there should be a note added to the documentation for the Yi component?

cexshun · January 11, 2018, 9:48pm

Glad it’s working for everyone. Seems I wasn’t the only one to get a new Yi camera for Christmas.

jeroenterheerdt · January 12, 2018, 12:15pm

Using the symlink I got my Yi Home 1080p camera to work. However, as far as I can see there is no live feed in HASS. Is that correct? When would video show up in HASS?

ronendayan · January 12, 2018, 11:09pm

Thanks for it man,
Solve my problem with YI Dome

kjacksonmusic · January 19, 2018, 1:41am

how do i do this… running HASSIO?!

Thanks

Rich_Paul · January 27, 2018, 9:30pm

Hi mate

I added the symbolic link to root directory of the camera but I’m still not seeing anything in Ha. Camera not available…

I can see mp4s in the tmp/sd/record dir but ha isn’t displaying.

Any ideas?

Rich_Paul · January 28, 2018, 1:19am

Now getting permission denied now. I updated my pub key and did an update after following another thread.

Any help would be appreciated

cexshun · January 29, 2018, 3:59pm

Have you tried manually FTPing to the camera from the Pi to make sure everything is working? I find it best to troubleshoot 1 aspect at a time and verify it’s working.

Also, if your FTP password has special characters, it will break. My password had an & in it, and it was causing errors.

Rich_Paul · January 29, 2018, 4:23pm

Thanks for your advice - I’ll try it in a bit!

No special characters, just capitals and numbers.

Rich_Paul · January 29, 2018, 5:06pm

Here’s what I wrote in another thread for some background info. (haven’t tested ftp yet - Mrs on laptop!)

This is my config:


ffmpeg: ffmpeg_bin: /usr/bin/ffmpeg 

camera:

- platform: yi

name: Baby Cam

host: '192.168.0.29'

user: root

password: ***

path: /tmp/sd/record

- platform: local_file 

file_path: /home/pi/screenshot.png

Here is the error i get (iv hit a few now!) And in Homeassistant im getting - ‘Image not aviaiable’


2018-01-28 20:20:01 ERROR (MainThread) [haffmpeg.core] FFmpeg fails program arguments must be a bytes or text string, not NoneType

I have put the symobilc link on the camera
i have added the path to the recordings in config…yaml
I can see the mp4s in sd/recordings/ with datestamped files
i have installed ffmpeg
i can see another local file image using the camera component
i have added the ffmpeg component with the location of where its installed: using:

sudo find -name ffmpeg

OK, it sounds like FTP may be fine and the issue is with FFMPEG or your config somewhere. When you can test FTP, we’ll know more. Here’s my config, and it’s working with 2 cameras currently.

  - platform: yi
    name: Living Room
    host: 192.168.1.152
    password: !secret yi_cam
    ffmpeg_bin: /usr/bin/ffmpeg
    ffmpeg_arguments: '-pred 1 -vf scale=800:450'

Edit: Here’s the command that is executed when HASS attempts to pull the video. This command will help troubleshooting a lot.

ffmpeg -i ftp://root:*****@192.168.1.152:21/tmp/sd/record/2017Y12M24D17H/47M37S.mp4 -an -frames:v 1 -c:v mjpeg -f image2pipe -

Replace **** with your password. Change IP to your camera IP address. Change the path and mp4 to an actual file that exists on the device.

Rich_Paul · January 29, 2018, 6:52pm

Thanks mate.

Right done all that, i get illegal instruction. The file definitely exists as copied the URL into IE and it downloads it:

ftp://****@192.168.0.29:21/tmp/sd/record/2018Y01M27D19H/30M00S.mp4 </code


Any other ideas?
