Hi everyone,<br><br>I've been spending a few hours to find any technical solution to this problem :<br><br>I want to send the MPEG4 stream I get from an IP Camera (Axis) to my piece of software which does motion analysis.
<br>Until now I've been able get the MPEG4 stream and save it to a file using a sligthly modified version of openRTSP.<br> Then I open the file in my program and I extract the frames using the library OpenCV (in fact it uses ffmpeg to do it).
<br>I have tried to do more or less the same using testMpeg1or2VideoReceiver, but I can't see where i can input the username<br>and password (it is absolutely mandatory to have it for me) for the camera.<br><br>1. My goal is to avoid the file saving, because I need a live processing, so I thought about using a named pipe... Could you
<br>give me any clue about the subclasses I should create or modify ? I've read about FramedSource and DeviceSource.. but<br>I'm not sure of which one I should modify. This library is quite big, and I don't know from which side start !
<br><br>2. My other question is about the named pipe... I also thought I should use a "home made" buffer (a char* or anything...). <br>This way i could have a complete control on the flow of data (i already did that in MJPEG). Linked to the preceding question,
<br>what class should I study/modify/grow ? Can you tell me which solution is the most reliable ?<br><br>3. Bonus question : do you think ffmpeg is able to decompress frames coming from a buffer ? I made a few try on a file, but I have no ideas on
<br>the behavior when it is in this particular context.<br><br>Thanks in advance.<br><br>-- <br>Robin Penea
