  • iPAD Streaming video to a ffmpeg server. front facing camera

    6 décembre 2011, par IrishGringo

    This is a video chat type program.
    My project is to write a native ObjC app that will stream video from the front facing camera to a server. This server will format and relay to be sent to another location.
    In a related question, I want to display video streaming from the server. The video server will probably be running ffmpeg for formating.
    But this question is just asking advice for the iPAD project. I wanted to get comments about issues I need to be thinking about.

    This is my strategy :
    I was thinking of using AVFoundation framework to stream from the cam to a URL server. I don't know if I will be formatting on the client or no, so some comment there would be interesting. http://developer.apple.com/library/mac/#documentation/AVFoundation/Reference/AVFoundationFramework/_index.html

    For streaming the video, I was going to be using :
    http://developer.apple.com/library/IOs/#documentation/AVFoundation/Reference/AVCaptureSession_Class/Reference/Reference.html#//apple_ref/occ/cl/AVCaptureSession

    so if someone has some ideas/suggestions... extra code I can look at. I would appreciate it.

  • Video Surveliance application by connecting DVR

    14 mai 2014, par iMOBDEV

    I am trying to connect to the DVR so that I can view video recording on my IOS device, I tried to search a lot but could not find a single useful link to move ahead with connecting to the DVR. I found that, it can be done using FFMPEG, but could not be able to do what to do and how to do.

    What I need to do is : connect to the IP address and port where the DVR is configured, give username and password for that DVR to connect to the DVR. Something like following link :

    https://itunes.apple.com/en/app/vmeye/id365532547?mt=8

    Guide me with useful links to move ahead with connecting to the DVR.
