    Capturing primary and secondary cameras simultaneously

    Dear all,

    wondering if anyone has tried (with or without success) to simultaneously capture video with the two cameras of a given device (in my case a Nokia 5800).

    Thnks,

    Cris

    You could take the Camera exmaple and try yourself, anyway, previously that have not worked, since the camera is designed in a way that only one application can use the camera at any given time, as well as it was limiting the usage to one of the cameras at any given time, though I have not checked this with 5th edition, so maybe you could verify the behaviour.

    No need to try, I can confirm that with any currently available Nokia device only one camera can be used at a time. What would be the use case for such scenario?

    In the case that it is not possible to capture video with two cameras at once, what is the maximum shooting frequency that can be achieved in a given phone camera?

    Thnks!

    In the worst case, is there any chance on messing up with the assembler of a given phone? Although I'm not aware of it, I'm sure there is a way to hack into the deeps of the machine, isn't it?

    Is it a continuation of which question?

    Sorry about the mess. I re-formulate my question:

    * I was just wondering whether it would be possible to directly program in the assembler of a given phone to capture videos from both cameras. That is, whether is possible in terms of hardware.

    * My second question was about the maximum shooting rate. That is how many photos per second can be taken.

    Thanks!

    No amount of hacking will allow you to use both cameras at the same time.

    Depends on many things. Shooting still images in Exif format capture time might be several seconds in the worst case. Using burst mode you might be able to get 2-3 images per second. And all this is of course image size dependent. Capturing images in bitmap format is normally slower than capturing in Exif format. Using view finder or video capture you typically receive 15 frames per second.

    Support for all this very device specific.
