AMR Codec ConfigureL method not working on Nokia N70 (It works on previous phones)

[AlfredoRU]

Hello!

We configure the AMR Mode using CMMFCodec::ConfigureL method and passing TAmrEncParams using a cast.

This way works well in 6600, 7610 and 6630 phones, but we have
noticed that CMMFCodec::ConfigureL leaves with
"KErrArgument -6 Bad request" in Nokia N70.

Thanks for your help.

Hi,

For N70 and newer devices, aConfigType parameter passed to CMMFCodec::ConfigureL() must be KUidMmfCodecAudioSettings (0x10203622). Anything else and it leaves with -6 (KErrArgument).

Previously, aConfigType value didn't seem to be used for anything (at least with AMR).

Hello!
Do You mean:

        // Set the Better Quality
        TAmrEncParams encParams;
        encParams.iMode=7;
        encParams.iDTX=FALSE;
        
        encoder->ConfigureL(KUidMmfCodecAudioSettings, (const TDesC8&) encParams);

This may work to set the maximum quality?

NOTE: How do you discover this tip?

Thank You ;-)

Hello!

This code don't work.

It leaves with -6 (KErrArgument)

        TAmrEncParams encParams;
        encParams.iMode=7;
        encParams.iDTX=FALSE;
        
        TUid amrCodecUid = TUid::Uid(KUidMmfCodecAudioSettings);
                        
	TRAPD(error, encoder->ConfigureL(amrCodecUid , (const TDesC8&) encParams));

How do you configure AMR Mode in N70 and newer devices?

Thank You

I'm sorry. The previous code works properly.

Now I'm able to configure the AMR Codec to use maximum quality mode
(AMR MODE 7)

Have a nice weekend!
