Hi Guys,
My current project might need to use AUDIO_SOURCE_REMOTE_SUBMIX as audio source to be streamed out just like wifi-display did.
in the sample code, i've already be able to use AUDIO_SOURCE_DEFAULT as audio source and encoded it AMR or AAC and saved as .m4a file.
But when I set AUDIO_SOURCE_REMOTE_SUBMIX as source, i got segment fault.
the code to get input source is:
sp<MediaSource> source = new AudioSource(
//AUDIO_SOURCE_DEFAULT, // ok
AUDIO_SOURCE_REMOTE_SUBMIX, // error
kSampleRate /* sampleRate */,
kNumChannels /* channelCount */);
the log when use AUDIO_SOURCE_REMOTE_SUBMIX is:
D/AudioHardwareALSA( 142): AudioHardwareALSA::getInputBufferSize sampleRate:8000,format:1,channelCount:2
D/AudioHardwareALSA( 142): AudioStreamInALSA::getInputBufferSize sampleRate:8000,format:1,channelCount:2
W/AudioPolicyManagerBase( 142): getInput() could not find profile for device 80000100, samplingRate 8000, format 1,channelMask 000c
E/AudioRecord( 1908): Could not get audio input for record source 8
F/libc ( 1908): Fatal signal 11 (SIGSEGV) at 0x00000010 (code=1), thread 1908 (audioloop)
the audio source MACROs are defined in file ./system/core/include/system/audio.h
Does this error means that current RK3288 audio driver doesn't support? or I need to get some proper pemission to do so?
any comments are welcomed
thanks in advance
Maye
