Hi,

example, which is part of Symbian 8.0a FP2 for series 60 is fully functional. We test it on N6630.

Hi,

I downloaded SDK from http://www.forum.nokia.com/main/0,6566,034-4,00.html. It is approx. 150 MB in size.

The example I downloaded from http://www.forum.nokia.com/main/0,65...3-&fileID=6406
Sorry it is not part of SDK...

But the example is little buggy(screen dimensions, etc.) and engine is not well written, but on device it works. On emulator of course not.

Hi

I went through the example but unfortunatly i couldn't get the solution for my ques. I want to read video data from internet into a buffer and then play it. As a trial i read a .3gp video file into a buffer and tryed to play it as follows.

In Document class --------->>
TDes8* iBuffer;
iBuffer = new(ELeave) TBuf8<10000>;

In AppUi class ---------->>

RFs fs;
RFile videofile;

User::LeaveIfError(fs.Connect());
CleanupClosePushL(fs);

_LIT(KFileName, "c:\\Nokia\\Videos\\Video(09).3gp");
TInt err = videofile.Open(fs, KFileName, EFileRead|EFileStream);
if (err==KErrNone)
{
// file opened ok, proceed reading
TInt fstatus=videofile.Read(*((CStrPlayerDocument::Static())->iBuffer),(CStrPlayerDocument::Static()->iBuffer)->MaxSize());

if (fstatus!=KErrNone)
ShowMessageL(_L("Error loading audio sample!"), true);
else
ShowMessageL(_L("Loading complete!"), true);
}

else
{
// failed to open file
// ShowMessageL(_L("Error loading audio sample!"), true);
}

videofile.Close();
// pop and destroy resources pushed into stack
CleanupStack::PopAndDestroy();

In VideoPlayer Engine ------------->>

After doing these things i replace the OpenFileL() method in the engine as follows

iPlayer = CVideoPlayerUtility::NewL( *this, EMdaPriorityNormal,
EMdaPriorityPreferenceNone, aWs,
aScreenDevice,aWindow,aScreenRect,
aClipRect );

iPlayer->OpenDesL( aDescriptor );

Then i did the things like play stop and other things as normal. But it dosen't work and didn't gives any error msg. But it properly work with a video file and FileOpenL method. So how could i play video data existed in a buffer.

Hi STeN

Grateful if you let us know what example code you are talking of, as the link you have placed is no more valid.

Thanks

Hi,

I really don't remeber which example it was, but if you look on page

http://www.forum.nokia.com/main/0,,1_32_30,00.html

You'll find in section called "Series 60 - Camera & Video" a lot of video and camera examples

Good luck
STeN

Thanks SteN

I tried the VREX example on 6630, but no success with the OpenDesL.
I can succesfully open the file into a buffer, then create a descriptor to the buffer, and use OpenDesL to open the descriptor, but nothing happens. No errors, no crash, just doesn't play anything

Rasika, have you been able to make it work on 6600 or 6630

Thanks
Tom

To play a buffer using CVideoPlayerUtility::OpenDesL, you need to load the complete movie into the buffer, also the buffer length should be same as the movie data length. Otherwise write your own MMF controller.

I have tried using openDesL() to play a local video file. I am able to play in following cases ---

1) when i load complete file into the descriptor
2) when i load starting part of file with some minimum threshold(5000 bytes in my case)

BUT......... If i load file less than this minimum threshold i get KERRNOTSUPPORTED.

Why is this so ???
