  1. Re: CCamera::Reserve(), KErrAccessDenied failure on Symbian^3

    There is nothing you should (or can) do after receiving "camera no longer reserved" event. At that point the camera resource is controlled by some other application.
  2. Re: CCamera::Reserve(), KErrAccessDenied failure on Symbian^3

    I think this is the problem. The non-camera specific part of your application will use up all the graphics memory in the system and there is no change for the camera to run. The delay you are...
  3. Re: CCamera::Reserve(), KErrAccessDenied failure on Symbian^3

    Are you using excessive amounts of graphics memory? On these devices the graphics memory is shared with camera. Typically if there is not enough memory you could get access denied on camera.
  4. Re: Ways to edit video frames during record process

    In principle you can do this but the performance will be severely limited. On most devices CCamera::PrepareVideoCaptureL() does not allow you to select full size video frames anyway so you have to...

    Re: Speed up Camera

    Hi H0LL0

    You did not mention the device you are working on? Most likely the device is optimized for capturing JPEGs, capturing bitmaps will make the data flow non-optimal. Also I don't know what...

    Re: Face Camera Problem

    Most probably preparing image capture fails because of unsupported image size index == 1. There might be only one supported image size i.e. index == 0. The example is very much hard coded. The...

    Check the error code accompanied with the event. If it is != 0 the focus failed.

    Re: N8 access to face detection functionality

    ecamfacetrackingcustomapi.h is a platform API so there is no guarantee that it will not change or will be supported in future platforms. Although the API supports retrieving the face rectangles...

    Re: N8 access to face detection functionality

    @pixsta: there is no public API for using the face detection / face tracking functionality in camera. Just out of curiosity: what sort of access you would need? What is the use case?

  11. Re: My application facing "already in use" error problem in Symbian^3(N8)..

    It is always preferred to use New2L when supported (all the latest products support it). This might not fix the problem though.

    Are you sure that there is no other camera application running in...

    Can you try CCameraImageProcessing::TransformationValue() function? It provides the same functionality.

    Re: How to record HD video on Nokia N8?

    Now reading again your post I see you would like to access encoded frames and not raw YUV frames. That might be possible using CMMFDevVideoRecord.

    Re: How to record HD video on Nokia N8?

    As far as I know the native application also uses CVideoRecorderUtility. Downloading the source might give you some tips on using it though.

    The native app does not receive raw video frames but...

    Re: How to record HD video on Nokia N8?

    You can't record HD video using just CCamera/ECam. The video functionality there is for limited use cases only. Is your target is to capture HD video you would want to stream the frames directly from...

    Re: Camera observer

    Hi,

    The behavior you describe is not directly supported by ECam.

    I think that you can reach similar functionality if you create CCamera using New2L() and use the lowest possible priority...
