Thread: How does Cycorder works?

  1. #1
    Default How does Cycorder works?
    Do you guys have an idea of how Cycorder takes video with the build-in camera? (Or how iPhone video recorder does this)?

    I know it's possible to direct access the camera using the private framework "PhotoLibary" and that works out very well but i'm only able to take pictures with that.

    I think Cycorder uses the camera in a much lower level then "PhotoLibary" does, maybe even by accessing the camera's hardware and calling the pins directly? The question is, how does the creator of Cycorder (saurik) knows the way to do this? I've emailed him but he won't give me detailed information which I understand ()

    I want to know this because i'm trying to create a client which makes it possible to make a videocall to another client we've created... Something like Qik but not streaming to the internet, just to another client.

    Hope you can help me out a bit by giving me some hints/tips/etc.

    im pretty sure all he does is takes single images very often (upto 15 per sec, therefore 15fps) and puts them into an array of pics. he then converts these arrays to video using some encoder...

    You need to read the Cycorder thread: Saurik have direct access to video, thats one of the main differences with IVR.

    No he doesn't, he is accessing the camera directly and I just want know how he is doing that.

    For example, with the newest firmware (2.1) some PrivateFrameworks (like PhotoLibary) are changed so developers needed to change their code. Cycorder kept working without updates so I guess he is not using the private framework 'PhotoLibary' which is used for taking pictures like the way you mean.

    So if anybody has an idea how Cycorder works, please let us know

    well on linux you can easily capture your webcam like this
    cat /dev/video0 > /home/user/SomeFile.avi

    it must be something similar,
    maybe a hidden device node? or one that is created temporarily...

    i cant find the camera in /dev/ on my iphone. also not the microphone
