[android-developers] Re: MediRecorder query

[ani]

check this file libmediaplayerservice/MediaRecorderClient.cpp.
This client i guess gets called by libmediaplayerservice/
MediaPlayerService.cpp file which gets the object of
MediaRecorderClient.


In this file(MediaRecorderClient.cpp) we are creating the object of PV
media and passing it to user to set the audio source for recording.
This file has this call MediaRecorderClient::setAudioSource for
setting the audio source.

This call in-turn goes to PV framework(external/opencore/android) for
setting the audio source.

How your call IMediaRecorder-setAudioSource is mapped to
MediaPlayerService.cpp file is left as an exercise for you.

[android-developers] Re: MediRecorder query

[Anandi]

Thanks for the reply ani.

I am tracing the code flow of setAudioSource() from java layer to jni
and to cpp.

After reaching at IMediaRecorder-setAudioSource() i can not trace the
code further. I mean i couldn't find the code trace going in
android_audio_output.cpp anyway.

I know this is very weird question but please help me in this.

Same is the case with setVideoSource. I can not trace where the
mediaRecorder get Camera object.

Please help.

Thanks

 Answer for your question is :

 Can anyone please tell me the location where the audioflinger,
 surfaceflinger and cameraservice talk toMediaRecorder'sAPIs?

 PV framework talks to audioflinger to supply the decoded audio
 data.You can look 
 inhttp://android.git.kernel.org/?p=platform/external/opencore.git;a=tre...

  android_audio_output.cpp is the file which talks to audioflinger and
 supplies the audio data.

 Regarding surfaceflinger and cameraservice i am not sure how they talk
 to framebuffer driver.You can check the jni code and find out that.
 Or someone has a better answer please share.

[android-developers] Re: MediRecorder query

[ani]

 Is there any relation between MediaRecorder and AudioRecord?

AudioRecord-for applications which require audio processing.

Media recorder- for applications which just wants to record audio by
using platform default values.

It would be better if someone from android team can shed more light on
this???
