Where To Buy A 360 VR Rig for Xiaomi Yi Action Cams.

Warning (Fixed in next release - coming soon..)
Photo mode does not currently work with Frieds Custom firmware - please use stock 1.2.13.
https://dashcamtalk.com/forum/threads/xiaomi-yi-custom-firmware-with-lastest-revision.13557/

Update 25L cameras fw 1.3.o
Please make sure you downgrade to fw 1.2.13 as bitrates have changed in the new release and I haven't had time to test this release. I am waiting for Xiaomi to officially release it for the older cameras before putting effort into supporting this fw.

Current Device Support
Android 5+

What variance in sync are you getting when starting video recording through the app? Does it give you solid frame level sync, or perhaps even millisecond sync?

What routers have you tested this with? I am working on reflashing the original firmware on my DSLRController'd TPLink portable router and should have some feedback soon afterward 🙂

Thank you!
 
I don't have solid sync yet - The cameras all start recording and then I push a 400ms tone/beep out.
The plan for future release is to sync time with android phone - push a script onto each camera via telnet that is executed to start cameras 5 seconds in the future.

Clapper and rotation is still recommended currently until future releases.

Tested with local BT homehub5 router and One Plus One, Note4 and Samsung S6 mobiles in hotspot mode - portable router will be useful once I go above 10 cameras.

Viewlet -
- 25:32 shows you hitting record and beep sounds 😉

Solid plan 😎
 
Take a look at your app screenshot, it's very pretty UI !

I'd like to know, how to trigger video starting via telnet ?
 
I havent looked at the telnet I'm going to execute the Json call direct from the camera from script on localhost using telnet.


Not from remote to camera this should fix the latency issue.

And use 'at xx:xx:xx' to specify when to run the call from the script on the camera.

If you find the direct telnet call let me know - I would be interesting to see if there is much difference in latency of the calls.

I can only create or modify a "amba shell file" with telnet, and let it run with autoexec.ash loop.
something like this:
Code: 
#autoexec.ash
while true
do
  sleep 1
  d:/do_some_thing.ash
done

But if I try to sync all cameras date & time using ntpd, the autoexec.ash won't run any more, as because ntpd will cause "sleep 1" stop.
something like this:
Code: 
#telnet linux command
ntpd -d -n -q -p [date-time server ip address]
e.g.
ntpd -d -n -q -p 192.168.1.101
 
I'm not planning to use ntpd..

My thoughts were to get date time from where the app is installed PC or mobile and sync with that across all devices.

Something like this

Code: 
date -s "19 APR 2012 11:14:00"

Code: 
hwclock --set --date="2012-04-19 16:45:05" --localtime

What do you think?
All cameras will sync with the time from app device. Maybe slight latency. Need to test..

hello,

i will test your application on samsung note 4 with Cube rig and 6 xiaomi yi. On your website it's the lattest version of application ?
 
Yes latest version.
There is a known memory leak swapping modes that will crash the app.

Otherwise it should work well.
 
The most suitable option would be a choice of settings of photos / videos.
I'm looking forward!
 
Hello i have followed your steps on the site and successfully connected all the 6 cams to my note 4 but they don`t connect to the brahma app... as you see here..
one step that confused me was
  • Update line 51 of \wifi\sta.sh and manually set the ip of your camera or dynamically set by commenting this line and uncomment the following line
i left it like as its.. i didnt change anything.. i only added my SSID ana PSK... in the \wifi\wpa_supplicant.conf and it connected but it didnt wanna connect to brahma app

so my guess it something has to do with the camera IP..

so

1- how do i know each camera ip address ?
2-what exactly should i write in the line 51 and what should i delete because when i asked stephen he said leave it as its it will auto assign ip or sth like this?
3-what should i write in the brahma-6 app when i configure each cam IP address.. ?

thanks

Have you clicked the menu top right and added the address of each camera?

BTW I'm finding this app really good, very stable and the cameras are very close to being synchronized when they go off. I can never get the preview to load (I may not be waiting long enough, but the image is there on the camera)

I'm using the Android Wifi Hotspot rather than any other apps and it's working well.

Yeah obviously i clicked to enter the Camera IP manually... my problem is with that exactly as i mentioned above..
 
I never got it to work with a fixed IP. Does your wifi hotspot give you the IP address of each connected device? If so use that.
 
I believe the fox-fi addon will give you the ip address -
pad_screenshot_240x180.jpg


I don't use fox-fi I just use the OOTB android hotspot and it tells me what's connected and the IPs.
Steven uses fox-fi and Note 4 and hasn't had any issues.

I use fixed IPs when connecting to my local router and it works fine.

I took a look at his video -
around 23:00 it also doesn't show his IPs but he can connect so I've reached out to ask him what magic he does with the note 4.

ok wait.. he just told me.
He says there is another window that shows all the ips connected its the default android app that shows you them there.
You should be able to just swipe down and see the android menu with the IPs. - hope that helps.

Beek - Preview there is a known bug where the preview wont display - this is fixed in the next release.
You can fix it in this release but its a bit of a long manual process where you update the camera settings on each phone I think you need to enable wifi auto on in the settings and it fixes it from memory..
 
Hello,
Six camera to connect app and take a picture.
first is possible.
However, it is not possible to the next photographing
