Hello, My application cannot handle the JNIE overhead, as I need to make 2 JNIE calls to the native C/C++ code for every 20msec. So I am trying to use the native media libraries and the realted C/C++ files provided by Android in the folder "//external/srec/audio/test" of the donut build. Ex. AudioHardwareRecord, AudioInRecord etc.. I am implementing all the calls in the native layer.
I am using the sampling rate as 8000 and want to read 160 samples (320 bytes) at a time. I used the following values to create the AudioRecord.. record = new android::AudioRecord( android::AudioRecord::MIC_INPUT, /* Input Source */ sampleRate, /* Sample Rate - 8000 */ android::AudioSystem::PCM_16_BIT, /* Format */ numChannels, /* Channel Count - 1 */ 1, /* Frame Count */ android::AudioRecord::RECORD_AGC_ENABLE, /* Flags*/ NULL, /* Callback Function */ NULL, /* Context for use by the callback receiver*/ 1 /* Notification Frames */ ); It says "success" after creating this interface but I am getting the error "Bad Value" if I am doing the InitCheck. And it is crashing once I start reading the samples or if I try to retrieve the configured sampling rate. Has anybody tried to access this native code? Any clue in this regard will be very helpful. Thanks in advance. Vishal Gaonkar --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
