I recently bought an IP Camera to monitor my house. There is a web access to view the video stream but not to record it.

Here is the IP Camera in question, it should work with every other similar product.

So I made a simple example which does the job.

Here is the code :

#include <GUIConstants.au3>

#include <StaticConstants.au3>
#include <WinAPI.au3>
#include <GDIPlus.au3>
#include <Memory.au3>

#region Global Vars
Global Const $sProgramTitle = "IP Camera stream + record"

;EDIT THE FOLLOWING LINE ONLY:
Global Const $iIPAddress = "192.168.1.99", $iPort = 99, $shtauth = "yourauth=="

Global Const $STM_SETIMAGE = 0x0172

Global $blRecording = False, $blGUIMinimized = False
Global Const $sRecordDir = @ScriptDir & "\ip_camera_stream"

Global $bRecvtmp = Binary(""), $bStream = $bRecvtmp

Global Const $iContLengthLen = StringLen("Content-Length: ")
Global $sStream = "", $sTrim2ContLen = ""

Global $hBMP = 0, $hGraphics = 0, $hHBITMAP2 = 0, $hFamily = 0, $hFont = 0, $tLayout = "", $hFormat = 0, $hBrush = 0
#endregion Global Vars

TCPStartup()

Global $iSocket = TCPConnect($iIPAddress, $iPort)
If @error Then
    MsgBox(16, $sProgramTitle, "Could not connect !")
    Exit -1
EndIf

Thanks for the awesome script! I have modified it to give the option to toggle between multiple cameras and also display 2 at once! works great - except the second camera has approximately 7 second delay. Any ideas how I can fix that?

Thanks again for the great script!

I will take a look at it when I will have the time to test it in real conditions.

I might have told you (this means maybe nothing in english...) I created a script to display up to 4 cameras, however I was too lazy to finish it BUT I have to, so someday I will post it.

i think it might have to do with these lines in the while loop....

$bRecvtmp_A = TCPRecv($iSocket_A, 4096, 1) ;4kb
If @error Then ContinueLoop

$bRecvtmp_B = TCPRecv($iSocket_B, 4096, 1) ;4kb
If @error Then ContinueLoop

The original code does an exitloop instead of continueloop but exitloop exits the script gracefully. continueloop crashes it.

This seems to be the issue not sure yet tho

It's wrong indeed.

 

If nothing is received on the socket A, all the script of for the camera B will be paused.

;Instead of
...
If Not BinaryLen($bRecvtmp_A) Then ContinueLoop
$bStream_A &= $bRecvtmp_A
...
 
;do
...
If BinaryLen($bRecvtmp_A) > 0 Then
    $bStream_A &= $bRecvtmp_A
    ;process camera A
    ...
EndIf
 
;socket B + process camera B

cool - i wrapped the IF statement around the entire processing of camera_A (in the while loop)

does this look like it will fix the crashes?

wasnt sure if you meant i should also make the same change to camera_B

testing it now to see if it crashes...

sorry to be a bother with this - i have a bunch of users using this and its crashing for all of them - *sigh*

thanks soooo much for your help!!!
