AMR-NB recording with example where to stop and save content automatically?

[FrankTheFox]

Hi,


just for testing purposes i want to stop the recording
1. after a while (fixed length)
2. when stopped by the user

i use this function for trying out :

void CAudioStreamEngine::Stop()
    {
    // if input or output streams are active, close them
    if (iInputStatus!=ENotReady) 
        {
        iInputStream->Stop();
        //ShowMessage(_L("\nRecording stopped!"), ETrue);
        iBufferOK = ETrue;
        iInputStatus = ENotReady;
        TInt Err;
        TRAP( Err, SaveAudioFileL() );
        if( Err == KErrNone )
        	{
        	//do something!
        	}
        }       
    if (iOutputStatus!=ENotReady) 
        {
        iOutputStream->Stop();
        iOutputStatus = ENotReady;
        ShowMessage(_L("\nPlayback stopped!"), ETrue);
        }
    }

if i run the code and let the program run the overall length( fixed ) it writes the file and responses:
"Recording complete!" in "MaiscBufferCopied".
But when i stop the recording by stop menu i get an error : recording error : -39 from "MaiscBufferCopied".
The file seems to be written...

So where is the best location to put " SaveAudioFileL()"

[vineet.jain]

in the audio streaming example under the callback fucntion MaiscBufferCopied,
you must be having a else condition which is:

else if (aError==KErrAbort)
{
// Recording was aborted, due to call to CMdaAudioInputStream::Stop()
// This KErrAbort will occur each time the Stop() method in this class is executed.
// Also, MaiscRecordComplete() will be called after exiting this method.
iStreamEnd = iStreamIdx - 1;
iBufferOK = ETrue;
iInputStatus = ENotReady;
SaveAuidoFileL();//call here for saving

}


Also if you interrupt the recording in between then ofcourse everytime it will give a panic code as KErrAbort i.e. -39

Hi,


i already inserted the SaveAudioFileL in "MaiscBufferCopied" but i missed:

iStreamEnd = iStreamIdx - 1;
iBufferOK = ETrue;
iInputStatus = ENotReady;

iAudioStream1->iEngine->Stop();

then i put this to the end of "MaiscBufferCopied"

CEikonEnv::Static()->AlertWin(_L("aaaabbb") );

but i never see aaaabbb when i press the stop menu from my view and run:

iAudioStream1->iEngine->Stop(); which is ...

// ----------------------------------------------------------------------------
// CAudioStreamEngine::Stop()
//
// stops playing/recording
// ----------------------------------------------------------------------------
...
    {
    // if input or output streams are active, close them
    if (iInputStatus!=ENotReady) 
        {
        iInputStream->Stop();
 ...

my guess if i call ..Stop() then "MaiscBufferCopied" is not called...

i think MaiscRecordComplete(TInt aError) is called when you give stop command from menu.

Hi,


first of all thanks for your patience. Well i figured out that

if(aError!=KErrNone) 
...

is correctly called first. And Then after that...

if(aError==KErrAbort)
...

so putting the last first and call !=KErNone only after some unexpected!

So "::MaiscBufferCopied" is called first and then "::Stop()". So thats makes me a little bit nervous but i think this is the AudioStream business as usual.
