C# Vs2005 test project, video overlay filter and convertCtrl error

Hi,

  I'm testing your MEPG2 UDP Module in c# vs2005. (I attached test project).

  I have receive several UDP streamings and put overlay in these videos and send them again.

  With your help, I've been working with AxltmmConvertCtrls and it works correctly with udp sourcefile and udp targetfile. but when I try to add Overlay filter to AxltmmConvertCtrl (like multimedia kit examples), ConvertCtrl doesn't send anything.

  First, I used like project references LMVVOvLy2.dll and LMVIOvLy2.dll that are included in \LEAD Technologies\LEADTOOLS Multimedia EVAL 16\Redist\MM\Unlicensed folder in Multimedia Kit setup, (I used these references) to create the overlay interface.

  If I comment the sentences about add video overlay filter to selectedVideoProcessors of convertctrl and the association between the overlay interface created and AxltmmConvertCtrl.GetSubObject, works correctly, (Obviously, without overlay image ;-)

 Another strange behaviour is with PreviewView of AxltmmConvertCtrl, if the source is a local video file works, but if it's UDP stream source doesn't work. I've checked this behaviour in examples projects and it happens too.


 One more time thank you for you help,

Maen,

 First, I used my app and one of your apps that it is in "mutlimedia sdk V16 capabilities" thread, (link).

 I comment you,

       I prepared a tests setting (core 2 duo and 3gb ram machine with XP and net.framework 3.0)  with  a vlc server in one side sending UDP Stream mpeg2-ts to one local port (22222), in the other side another vlc viewer was waiting in another local port (44444).
 
      Between the vlcs proccesses, I ran my app that receives in local port (22222) where vlc server sends udp stream and my app sends the new stream by local port (44444) where vlc viewer is waiting.
 
     My first question is check dlls reference, I don't know if I use the correct version for overlay filter!.
 
   If  I debug the c# vs2005 project, I can see that problem is when it's trying to add video overlay filter to selectedVideoProcessors of convertctrl sentence.
  Next sentence is the assignation in local overlay interface of convertctrl subobject, but this method getSubObject doesn't return the correct object (overlay interface) and returns a "System._____COMObject" (it means error).

   If I don't try to add overlay filter, it works fine.  (my re-streamer app receives and sends streams without problems).

   In the other hand, i've checked in the two projects (your one and my one) that if you use in sourcefile of convertCtrl one UDP Stream, previewView doesn't work, but if you use a local video file works fine.

 I think if you run my app, you can see and understand that i try to explain you. Could do you check them??

 I'm very interesting to buy MPEG2 Transport Module, but  i have to be totally sure that it can resolve my requerimients.

 I read in http://www.leadtools.com...eg2-transport-stream.htm that in that module there is a restreamer demo, and I don't find it. where is?


  Thanks,
            Mario


  
       
       

        

 

 

 

Maen,

  I'v checked with MPEG2 recompression and it works fine. (PreviewView and Overlay filter). but my requerimients are that i cann't recompress source video.

 Is there another solution?


  One more time, thank you and regards,
