capturing video using CCamera api

Hi,

Yes i have reffered that for capturing the video  but the problem is
that the video capture through StartVideoCaptureL returns a MMFBuffer which is raw video data in YUV format.now the problem is to encode that raw data to required 3gp format.


I have try to use MMFCodec but have not found any relevant video codec uid and TFourcc code so that i can get the object of MMFCodec class and process my raw data to required format using ProcessL of MMFCodec class.

Please do reply if u have any idea regarding this.

Cheers

Hi ,

I have already use this api (CvideoRecorderUtility) to capture video in a file successfully but unable to capture video in descriptor using opendescL of CvideoRecorderUtility.It is giving -5 error in openComplete.

Hence i go for CCamera API to capture video but facing problem in playing the video.So if u have any idea please let me know.

Hi Janza,

Thanks for the quick reply.what i m passing the argument in OpenDescL
by retrieving through following code please check this

CMMFControllerPluginSelectionParameters* cSelect =
      CMMFControllerPluginSelectionParameters::NewLC();
   CMMFFormatSelectionParameters* fSelect =
      CMMFFormatSelectionParameters::NewLC();

   // Set the play and record format selection parameters to be blank.
   // Format support is only retrieved if requested.
   cSelect->SetRequiredPlayFormatSupportL(*fSelect);
   cSelect->SetRequiredRecordFormatSupportL(*fSelect);

   // Set the media ids
   RArray<TUid> mediaIds;
   CleanupClosePushL(mediaIds);
   User::LeaveIfError(mediaIds.Append(KUidMediaTypeVideo));
   // Get plugins that support at least video
   cSelect->SetMediaIdsL(mediaIds,
      CMMFPluginSelectionParameters::EAllowOtherMediaIds);
   cSelect->SetPreferredSupplierL(KNullDesC,
      CMMFPluginSelectionParameters::EPreferredSupplierPluginsFirstInList);

   // Array to hold all the controllers support the match data
   RMMFControllerImplInfoArray controllers;
   CleanupResetAndDestroyPushL(controllers);
   cSelect->ListImplementationsL(controllers);

   TBool recordingSupported = EFalse;

   // Find the first controller with at least one record format available
   for(TInt i = 0; i < controllers.Count(); ++i)
      {
      RMMFFormatImplInfoArray recordFormats = controllers[i]->RecordFormats();

      if(recordFormats.Count() > 0)
         {
         iControllerUid = controllers[i]->Uid();
         iFormatUid = recordFormats[0]->Uid();
         recordingSupported = ETrue;
         break;
         }
      }


**************************************
then using the above format id and controller is in openDescL as follows
TDesc8* videoClip;
videoClip = new(ELeave) TBuf8<3000>;
iUtility->OpenDesL(*videoClip, aCameraHandle, iControllerUid, iFormatUid);

***************************
please check the above code do i have pass some wrong argument .
please reply as soon as possible.

Thanks in Advance

Hi Janza,

thanks for reply.as u have ask for the environment i have test it on nokia N80 handset (symbian9.0) using series 60 sdk 3rd edition.

Did u check the code
TDesc8* videoClip;
videoClip = new(ELeave) TBuf8<3000>;
iUtility->OpenDesL(*videoClip, aCameraHandle, iControllerUid, iFormatUid);
