On caf ics code, the sound files load can be stopped by setting "persist.camera.shutter.disable". It seems a CAF specific system property. AOSP does not have it. https://www.codeaurora.org/cgit/quic/la/platform/frameworks/base/tree/services/camera/libcameraservice/CameraService.cpp?h=b2g_ics_1.2#n297 sotaro ----- Original Message ----- From: "Sotaro Ikeda" <sik...@mozilla.com> To: "Randy Lin" <r...@mozilla.com> Cc: "amitav anand" <amitav.an...@accenture.com>, dev-b2g@lists.mozilla.org Sent: Saturday, October 19, 2013 10:55:31 AM Subject: Re: [b2g] Media Framework Queries >I noticed that during media playback for mp3 file, the traces were from >SYDNEY_AUDIO and MP3 Openmax component, but in case of Camera application, I >can see the traces from Awesome Player, Stagefright and then Openmax >component. B2G does not use AwesomePlayer at all, but uses MediaExtractor and OMXCodec. AwesomePlayer is not used in B2G. If you saw AwesomePlayer in the log, it come from android::CameraService. B2G do not modify android's CameraService, just removing the sound files.

I have tried media playback and camera services. Just to check the flow I had enabled traces in Awesome player and Stagefright. I am trying these use cases on emulator. I noticed that during media playback for mp3 file, the traces were from SYDNEY_AUDIO and MP3 Openmax component, but in case of Camera application, I can see the traces from Awesome Player, Stagefright and then Openmax component. Can Some one please clarify, is there any other media framework being used in playback case or I need to enable some macros to use Stagefright for playback.
