Video stream capture

Recommended Posts

Hello everyone,

I've got a very cr.. err low cost IP camera and I'd like to capture its video stream with autoit and save it to a file.

I've found this IP Camera script which looks to work ok for other people, unfortunately it doesn't with mine:

'?do=embed' frameborder='0' data-embedContent>>

I've played with FireBug and finally got the right URL which brings me straight to the video stream (only when using the below HTML):

<img onload="load_video()" src="http://IP:PORT/videostream.cgi?rate=0&amp;user=USERNAME&amp;pwd=PASSWORD&amp;next_url=tempsnapshot.jpg&amp;count=7" alt="video" id="imgDisplay">

This works great as it refresh almost instantaneously (I managed to get it to work with VLC too, but it's way slower in refreshing - talking of 10, 15 seconds delays).

Is there a way to capture this video stream and save it to a video format file?

I could then go ahead and try to build something around it.

Cheers!

This is url based?  Is there a standard API that your cr... err low cost camera has?

If it's only retrieving snapshots, have you tried InetRead() or InetGet()?


Common sense plays a role in the basics of understanding AutoIt... If you're lacking in that, do us all a favor, and step away from the computer.

Hi SmOke_N,

 

If it's only retrieving snapshots, have you tried InetRead() or InetGet()?

 

Thanks for your reply. No, I have not. Do you actually think it's a series of snapshots being updated? The video is very smooth but it might be.

As far as I know there's no API for it, this is the camera:

How would you use inetRead/Get in the case it's a sequence of pictures? Shall I run an infinite loop and save them all in a tmp folder and once done implement an avi builder (which I've seen on the forum if I'm not mistaking).

Thanks a lot :)

Me again.

I've tried the below, which got the snapshots but it's way too slow so I'm missing most of the "action".

#include <InetConstants.au3>

$sFilePath = @ScriptDir & "\jpgs"
$sFileName = "testimage"
$sFileExt = ".jpg"

$count=0

While 1

    $tempFileName=$sFilePath&'\'&$sFileName&$count&$sFileExt
    $hDownload = InetGet("http://IP:PORT/snapshot.cgi?user=myuser&amp;pwd=mypwd", $tempFileName,$INET_FORCERELOAD)
    $count=$count+1

WEnd

Can you post the "load_video()" javascript (<script>data here</script>) function?

I'm afraid it's not going to be very helpful, this is what I see with FireBug:

<td valign="middle" bgcolor="#E0E0E0" align="center">
<script>
document.write(imgsrc);
</script>
<img src="videostream.cgi?rate=0">
</td>

There's also an option to see the camera with a lower resolution (Mobile view) and that one is given by the below:

<img id="imgDisplay" onload="load_video()" src="http://IP:Port/snapshot.cgi?user=myusername&pwd=mypassword&next_url=tempsnapshot.jpg&count=41" alt="video">

I've also tried this with no luck:

#include <InetConstants.au3>

$sFilePath = @ScriptDir & "\jpgs"
$sFileName = "testimage"
$sFileExt = ".jpg"

$count=0

While 1

    $tempFileName=$sFilePath&'\'&$sFileName&$count&$sFileExt
    $hDownload = InetGet('<img onload="load_video()" src="http://IP:PORT/snapshot.cgi?rate=0&amp;user=myusername&amp;pwd=mypassword&amp;next_url=tempsnapshot.jpg&amp;count=7" alt="video" id="imgDisplay">', $tempFileName,$INET_FORCERELOAD)
    $count=$count+1

WEnd

Thanks for your support

Just trying to narrow down the actual stream and not the snapshot jpgs.

Might play around with directly (through the browser) seeing if you can connect to the videostream.cgi?rate=0

Hi,

InetGet needs a correct url, try this instead :

$hDownload = InetGet("http://IP:PORT/snapshot.cgi?rate=0&user=myusername&pwd=mypassword&next_url=tempsnapshot.jpg&count=7", $tempFileName, $INET_FORCERELOAD)

Don't forget to replace the IP/PORT etc.
 
I'm wondering what is the "count" parameter for.
 
Br, FireFox.

      but it incoded i can not read it

      This file includes all the source codes and a compiled .exe version of zPlayer, which is a stand-alone, simple, intuitive and easy-to-use, yet fully functional media player.  I made this to suit my purpose and you can tweak it to your taste. The source code is only about 1300 lines and only standard #include files were used.
      zPlayer was my first AutoIt project through which I was hoping to learn coding. A media player capable of playing back audio and video files was my initial goal, but video was beyond my capacity for my lack of coding experience. So zPlayer was born as an audio-only player and remained so up to Version 2.0.1.5.
      Just recently I decided to add video function to zPlayer now that I had gained some experience. I thought it would be possible, but I didn't expect it to be this simple. I made minimal changes to the existing code and added only about 80 lines and, voila, I have an integrated audio and video player, starting from Version 3.0.0.1.
      This player has the following features:
      - Play back all formats of media files which can be palyed back by the Windows Media Player in your computer
      - Depending on the file types specified by the user in zPlayer.ini file this player can be either audio only, video only or both.
      - Video window is independent of other windows and, when it is maximized, increases the immersiveness of the user
      - Graphical player similar to embedded Windows Media Player
      - Forward, backward, pause, repeat, shuffle funtion
      - Increase/decrease/mute sound volume
      - Change folders and create playlist for all media files in that folder and its subfolders, and support for manually-made playlists
      - Save play-back environment when terminating and resume that environment when restarting
      - With one click, you can see internet search results for the file selected in playlist
      - With a double-click, you can play back an item in the playlist
      - Search strings in the playlist
      - Option to see long file names including folder names
      - Resize the playlist and video windows, and restore them to their default positions
      - Very small footprint: very low CPU and memory usage, with only about 1MB when compiled
      - You can even hide all the windows and manipulate the player with hotkeys only
      Note: zPlayer is the name I used when I introduced the early version of this palyer in my blog back in early 2009 and, therefore, has nothing to do with the mobile media player of the same name which started marketing in 2015.

      zPlayer is the name I used when I introduced the early version of this palyer in my blog back in early 2009 and, therefore, has nothing to do with the mobile media player of the same name which started marketing in 2015.
      After I retired from active duty in 2002 I spent much time listening to music. First I started with CD's and LP's, then quickly moved on to mp3 files. I converted many of my CD's to mp3 and I collected many more from various sources which were freely available at the time. As the number of my mp3 files grew, I put them in folders according to their genres and my favorite classifications. I mainly used Windows Media Player to listen to them and I slowly began to dislike wmp because it had massive user interface while I just wanted to listen to music in the background while I was doing other work in the foreground, hopping between folders from time to time. It was the time I was beginning to learn AutoIt and I thought I should make my own player with AutoIt. Coming from a sales career with no experience in programming, it was not an easy task. Somehow, after about 2 years of learning and trying, I had my own audio player which worked with only hotkeys without any graphical interface. I gave it to some of my friends who were not as computer-savvy as I. They liked it but definitely wanted something to clcik with mouse. So I came up with very rude gui which took a form similar to what it is now.
      The attached source files include one au3 file, one icon file and 14 jpg files. The jpg files are used for drawing a graphical player and are fileinstalled in @DocumentsCommonDir folder. This player uses WMPlayer.OCX as its engine and supports all audio file formats supported by wmp and additional codecs installed. I would like to thank @Bilgus for kind answers to my questions and would appreciate it if anyone could review the code and give me any suggestion. This player works for me, but I don't know whether the code is presentable as an example. I am posting this here with a hope to learn much from AutoIt community.

      So I was playing with INet and downloading files and made a simple video downloader, or it can even be used for any file really.
      Just follow the reference section in INet_Settings.ini , and then run the script.
       
      Main Script <snip>
      INet_Settings.ini  URL - The target URL of the video you're trying to grab Data - This is the starting string, and ending string reference to look for the download URL itself. Settings - Only setting here currently, is the delay in which to wait for the file to download ### Reference for Start and End points for various websites <snip>
