Yes... BAK is available to Symbian Partners only.

Rewot, how can I obtain the Binary Access Toolkit?
Do I need to become a Symbian Partner?

Hi,
I am also using the CMMFDevVideoRecord. I find the same error as posted in the first post on N-95. But i managed to get the encoder to initialize if i do not use the direct capture or the preprocessor. I can not find how to give input to the encoder from video buffer may be there is something that I am missing

Hi,

I'm working on a video aplication for s60 3rd edition. I use devVideoRecord library from UIQ, because the files are not included in S60 SDK. I call the same methods listed on the first post but the Initialize method finish with code -2 (general error) too. I tested a N80, N91, and N73 devices, which implement the same DSP, an all of then return the same error.

This phones provide direct capture feature, as well as video from buffers, but none of the modes works!

I don't know what I'm doing wrong. Have anyone found something out about the issue?
Is this a problem related with the library, not from S60. Why the code only works on 3250?

I'm looking forward to hearing your replys. Thanks in advance.

Helo Rewot,

Have you found, how to use the CMMFDevVideoRecord class?
i have to use it to have video in a buffer.
can you send me an example how to use it.
Thanx.

Devvideo is not inluded in the standard s60 3rd Edition SDK just like Rewot said. You probably need a symbian DevKit to be able to use the devvideo library, unfortunately this is not so easy. You have to be symbian partner and perhapsÂ a Nokia partner too to obtain a devkit.

Please correct me if I'm wrong..

Hi

You right anton, Devvideo also can be found in DevKit (even sourace code i thing ), but it's much harder to get it than Binary Access Kit.

Hello

CMMFDevVideoRecord is a part of mmf api of symbian S60 3rd Edition, but isn't in standard sdk (only in binary acccess kit).

Regards
Rewot

In the document they said mmf\devvideo\devvideorecord.h is required but there is no such file in my epoc32\include directory

Finaly i succesfull initialize endoder on nokia 3250 (the same code on Nokia N80, still return -2 error). I have the question about input format of video/h63-200 mime type encoder. It sems that nokia 3250 support only 1 input format for this encoder, yuv image in 420Planar layer. Also , camera support only 1 format in Video Capture mode - yuv420Planar too. Is this two formats the same ? (encoder api has much more option for describe input format , see sdk help for detail).
And another thing - how start encoding ? N3250 doen't support direct image capture from camera - so i use SetSourceMemoryL before initialize. There is no option for set input buffer (or i miss it ?).
I call Start() and ther try to use WritePictureL, but it's crash app.
Code:

TVideoPicture       iVideoPicture;
TPtr8          iSourcePtr;

void CVideoTestAppView::FrameBufferReady(MFrameBuffer * aFrameBuffer, TInt aError)
{
   if (aError != KErrNone)
   {
      return;
   }
   User::ResetInactivityTime();

   TDesC8 * data;
   TRAPD( code , data = aFrameBuffer->DataL(0));
   if ( code == KErrNone )
   {

      iVideoPicture.iData.iDataFormat = EYuvRawData;
      iVideoPicture.iData.iDataSize= TSize(176,144);
      iSourcePtr.Set(const_cast<TUint8*>(data->Ptr()),data->Length(),data->Length());
      iVideoPicture.iData.iRawData = &iSourcePtr;
      iVideoPicture.iData.iRgbBitmap = NULL;
      iVideoPicture.iTimestamp = aFrameBuffer->iElapsedTime;
      iVideoPicture.iCropRect = TRect(TSize(176,144));
      iVideoPicture.iHeader = NULL;
      iVideoPicture.iOptions = TVideoPicture::EReqInstantRefresh | TVideoPicture::ETimestamp | TVideoPicture::ECropRect;
      iVideoPicture.iLayerBitRates = NULL;
      iVideoPicture.iEffect = EEffectNone;

      iVideoPicture.iUser = aFrameBuffer;
      TRAP(code , ipRecorderEngine->WritePictureL( & iVideoPicture ) )

App crash in WritePicture, TRAP doesn't help.

Hi I wonder which version of Symbain SDK you are using.

I searched through several versions of symbian I can't find devvideorecord.h which states on the API document. Also the linking library devvideo.lib is not avaible as well.
