Everyone knows that EasyGBS can be cascaded. In the recent test, EasyNVR was cascaded to EasyGBS, and the channel of the EasyNVR platform was accessed through EasyGBS. It was found that the video channel was very confusing, and the corresponding channel names were the same, but the playback content was Inconsistent.
Problem phenomenon
As you can see from the figure below, the channel name in EasyGBS is different from the channel name of EasyNVR, but the content is the same. However, in the EasyNVR channel with the same channel name as EasyGBS, the content of another camera is being played.
analyse problem
This phenomenon only exists when EasyNVR is cascaded with EasyGBS, so it can be locked into EasyNVR cascaded with EasyGBS first.
We observe that the channel name and other information corresponding to each channel on the page are correct, and then play channels 1-9 on EasyGBS are all corresponding to EasyNVR, after channel 10 is exceeded, it will be wrong, and channel 11 is playing channel 1. Channel 12 plays channel 2. So we suspected that EasyGBS may be reversed into EasyNVR channel number error.
/**
反解通道ID
*/
func ParseChannelId(code string) (channelId int, err error) {
var index int
channelIdStr := code[len(code)-5:]
for i, v := range channelIdStr {
if string(v) != "0" {
index = i
}
}
channelId, err = strconv.Atoi(channelIdStr[index:])
return channelId, err
}
EasyGBS sends a playback command to EasyNVR, and reverses the channel ID of EasyGBS to the channel ID of EasyNVR corresponding to EasyNVR.
Solve the problem
/**
反解通道ID
*/
func ParseChannelId(code string) (channelId int, err error) {
var index int
channelIdStr := code[len(code)-5:]
for i, v := range channelIdStr {
if string(v) != "0" {
index = i
break
}
}
channelId, err = strconv.Atoi(channelIdStr[index:])
return channelId, err
}
The effect after synchronizing the channel IDs of the two platforms:
