Group Discussion regarding Reolink cams

[GhostlyCrowd]

I've been working on getting better Standalone reolink cam support worked out. I'm not a pro so this is a discussion thread for us to have a group think about it.

Here are the basics that the cameras support.

*They have an API that can be probed for motion detection (this is already working)

Note: The “channel id” starts from 0

example

http://192.168.0.206/api.cgi?cmd=GetMdState&channel=0&user=admin&password=xxxx

*They have a proper snapshot url, that also supports calling a specified resolution for the jpeg

If you need to specify the width and height of the snapshot, please include the width and height parameters in the url (cannot be greater than the width and height of the main stream)

http://(ip address)/cgi-bin/api.cgi?cmd=Snap&channel=(channel id)&width=(Picture width)&height=(Picture height)&rs=(any combination of
numbers and letters)&user=(user name)&password=(user password)

Note: The “channel id” starts from 0

example:
1. Snap a picture of the ipc device
http://192.168.123.145/cgi-bin/api.cgi?cmd=Snap&channel=0&width=640&height=360&rs=000000&user=admin&password=xxxx
2. Snap a picture of the third channel of the nvr device

http://192.168.0.206/cgi-bin/api.cgi?cmd=Snap&channel=2&width=640&height=360&rs=0000010&user=admin&password=xxxx

*They support RTSP RTMP and HTTP FLV streaming natively (Main, Ext and Sub). (this might be very useful as maybe we can pipe the FLV stream directly to the cam proxy and to the Protect system. I'm actually sending the cam proxy as it stands now the flv stream. Recording works but no live view. ffmpeg also seems to be happy with the stream its also outputs its frame rate so no need for h264_metadata injection "tickrate" no weird errors or warnings at all.

Main stream:
rtmp://(ip address)/bcs/channel(channel id)_main.bcs?channel=(channel id)&stream=0&user=(user name)&password=(user password)

Ext stream:
rtmp://(ip address)/bcs/channel(channel id)_ext.bcs?channel=(channel id)&stream=0&user=(user name)&password=(user password)

Sub stream:
rtmp://(ip address) /bcs/channel(channel id)_sub.bcs?channel=(channel id)&stream=1&user=(user name) &password=(user password)

Note: The “channel id” starts from 0
example: 
1.Preview ipc device video
rtmp://192.168.123.145/bcs/channel0_main.bcs?channel=0&stream=0&user=admin&password=xxxx
2.Preview the video of the third channel of nvr
rtmp://192.168.0.206/bcs/channel2_main.bcs?channel=2&stream=0&user=admin&password=000000
flv  (Only supports h264 encoding format stream)
Main stream:
http://(ip address)/flv?port=1935&app=bcs&stream=channel(channel id)_main.bcs&user=(user name)&password=(user password)

Ext stream:
http://(ip address)/flv?port=1935&app=bcs&stream=channel(channel id)_ext.bcs&user=(user name)&password=(user password)

Sub stream:
http://(ip address)/flv?port=1935&app=bcs&stream=channel(channel id)_sub.bcs&user=(user name)&password=(user password)

Note: The “channel id” starts from 0
example: 
1.Preview ipc device video
http://192.168.123.145/flv?port=1935&app=bcs&stream=channel0_main.bcs&user=admin&password=xxxx
2.Preview the video of the third channel of nvr
http://192.168.0.206/flv?port=1935&app=bcs&stream=channel2_main.bcs&user=admin&password=xxxx
rtsp
main stream(H265 encoding type):

rtsp://(user name):(password)@(ip address):554//h265Preview_(channel number)_main
or
rtsp://(user name):(password)@(ip address):554/

main stream (H264 encoding type) :
rtsp://(user name):(password)@(ip address):554//h264Preview_(channel number)_main
or
rtsp://(user name):(password)@(ip address):554/

sub stream (sub stream only support h264) :
rtsp:// (user name) : (password) @ (ip address) :554//h264Preview_(channel number)_sub


Note: The “channel number” starts from 01
example:
1.Preview ipc device video
rtsp://admin:xxxx@192.168.123.145:554//h264Preview_01_main
2.Preview the video of the third channel of nvr
rtsp://admin:xxxx@192.168.0.206:554//h264Preview_03_main

*ffprobe output of the main flv stream
