please help. im stucked! sori for the long post, please understand.
@brief: need to run on a Trep650, development tool is CW for PalmOS ver 9.3,
using the PalmOS Garnet SDK
i tried using two APIs. first the PalmOnePhotoAPI. here's the part of the code
that calls the built in camera.
Err VideoPreview()
{
/** from the photo lib **/
PalmPhotoHandle photoH = NULL;
PalmPhotoCaptureParamV2 captureParam;
PalmPhotoCaptureResolution SupportedResolutions;
Err err;
Boolean cont = false;
// setup callframes
MemSet(&captureParam, sizeof(PalmPhotoCaptureParamV2), 0);
captureParam.fileLocation.fileLocationType = palmPhotoVFSLocation;
//captureParam.fileLocation.reserved = 0;
captureParam.fileLocation.file.VFSFile.volumeRef = volRefNum;
StrCopy(captureParam.fileLocation.file.VFSFile.name, p_fileName);
SupportedResolutions =
PalmPhotoGetSupportedCaptureResolutionsV3(PhotoLibRefNum ,
palmPhotoMediaTypeVideo);
GetDimensions(SupportedResolutions); //get dimendions for suported
resolution
captureParam.imageInfo.width = videoWidth;
captureParam.imageInfo.height = videoHeight;
captureParam.imageInfo.bitsPerPixel = 16;
captureParam.imageInfo.filesize = 0;
captureParam.imageInfo.fileFormat = palmPhotoPreferredVideoFormat;
captureParam.imageInfo.imageQuality = palmPhotoLowQuality;
captureParam.captureCallback = NULL;
captureParam.userDataP = NULL;
/** capture photo **/
photoH = PalmPhotoCaptureImageV2(PhotoLibRefNum, &captureParam);
//get last error
err = PalmPhotoGetLastErrV2(PhotoLibRefNum);
if ((err) && ( err != palmPhotoLibErrUserCancel ))
{ GenerateErrorMsg(err);
goto Done;
}
else if (err == palmPhotoLibErrUserCancel) // --> user press the
cancel button on the camera
goto Done;
Done:
PalmPhotoCloseImageV2(PhotoLibRefNum, photoH);
return err;
}
*** problem is the image on the screen on the preview mode is not moving it
stops on the first frame it capture. therefore cannot record a video. even if
i press the recording button, the image is stucked on the first frame it
capture and it does not direct me to the save/preview part.
second, i used the PalmOneCamera API. i called the StartStream (from the
CameraV3), the screen turns white and then it hangs. i had to do a reset on the
unit.
please, all inputs will be highly appreciated!! (in fact it is badly needed!)
thanks a lot!!
