So far, I've not made "test_pvauthorengine -test" work correctly, either. I tested recording amr & encoding qcelp all based on the OpenCore-2.00. They all work well.
'Record Audio' is just an App written in Java. You can find its source under packages/apps/SoundRecorder. And as it's well known, the App just supports encoding ARM default. You should modify it to meet your requirements by SIMULATING the case of AMR. Additionally, there's a switcher to control the current ContentType to record in packages/apps/Mms/src/com/android/mms/ui/MessageUtils.java. Just modify the func 'recordSound' to support qcelp also. In the file -- frameworks/base/media/java/android/media/MediaRecorder.java, there're AudioOutput & AudioEncoder enums, please adding Qcelp respectively to them. Above is the base & key work needing to do. The left is just to debug it step by step till the end. If you want to try AMR only, do not modify anything. It should already work well default. Maybe there's difference between 2.00 and 2.02. Just play it by ear. Finally, with 'logcat', you can find all info when testing your case, what you need to do is just trace it & find the error & resolve it step by step. You'll be sure to success. david 2009/5/4 chuan <terr...@gmail.com> > > Hi David, > Thank you for your quick reply. > > 1.
