Re: How to compile only part of the platform
Hi, Are you giving make at the root directory of the android. Generally make does an incremental build. But still you want to reduce the time in that case you have to trace from the main make file. and disable for all other make files. You can trace this by first looking at the the main make file which calls one more make file and that inturn calls few more make files. only thing you need to do is to disable the calling of all other make files other than wht u need. -Giri From: Mike Lissner To: android-framework Sent: Friday, 17 July, 2009 11:45:06 PM Subject: How to compile only part of the platform I'm working on some changes to the location framework, and I'm trying to test my changes in the emulator.

Re: Access to opencore audio decoders from application layer.
Hi Sandeep, You can put the if condition in the parser to read only till 10 sec and take the PCM samples from decoder output to a file -Giri From: sandy8531 To: android-framework Sent: Thursday, 16 July, 2009 12:46:10 PM Subject: Access to opencore audio decoders from application layer. My application needs to extract a 10 second portion of a audio file in PCM format and store it. On other platforms I have been doing this in Java using Jlayer decoder, but once I ported that to Android, it ran extremely slowly. It takes almost 50 seconds to decode a 10 second sample ! Since the opencore libraries are already available, I would like to be to use them as an alternative. I have been looking at it for a couple of days now. I would like to understand what options are available to me to be able to do this. My first approach was to develop a JNI stub and try and make a call out to the codec in the opencore shipped library, but it appears that those interfaces are subject to change and there is no guaranty of backward compatibility in a future release. The other approach I can think of is to take the opencore source and compile the codecs into a separate standalone jni library private to my application, and that way I avoid the backward compatibility issue. Before I go too far down any path I would like to run this by the experts and figure out what is the best approach. One more question - I saw in the opencore code that the decoding thread is run at a higher priority. Since my decoder would be running at normal application priority am I going to see a significant performance drop off ala Jlayer ? -thanks, Sandeep See the Web's breaking stories, chosen by people like you.

You can look at how this "config" information is passed from the aac
parser to the aac decoder. NOTE: The parameter values are not directly
sent to the decoder. Instead, they are sent in a buffer (called the
config buffer) which the decoder is supposed to understand and decode.

I am trying to use my own g711 decoder instead of the existing g711 decoder.

Yes, I'm using own file container type recognizer (file container
parser/demultiplexer):
1) which search for necessary magic sequence in the given file - and
making a desicion it's supported file type or not;
2) node (engine) - which would be a demultiplexer engine.
in general i want to implement demultiplexer (splitter) only, like the
opencore existing one (MP4).

Hi all,
I'm trying to develop own opencore wrapper around some file format,
for example MKV... i've created shared library called
my_mkv_recognizer.so, and put it into /system/lib folder.
The following interfaces are present in the library:
==
1) class CMyMkvSplitterRecognizerFactory : public
PVMFRecognizerPluginFactory;
2) class CMyMkvRecognizerPlugin : public
PVMFRecognizerPluginInterface;
3) class CMyMkvNodesRegistryInterface: public
OsclSharedLibraryInterface,
public NodeRegistryPopulatorInterface,
public RecognizerPopulatorInterface;
4) OsclSharedLibraryInterface *PVGetInterface( void )
{
printf("PVGetInterface()\n");
return OSCL_NEW(CMyMkvNodesRegistryInterface, ());
}
void PVReleaseInterface ( OsclSharedLibraryInterface* aInstance )
{
OSCL_DELETE( aInstance );
}
==
Then i've created config file: my_plugin.cfg, and put it into /etc
folder, this file contains the following strings:
(0x1d4769f0,0xca0c,0x11dc,0x95,0xff,0x08,0x00,0x20,0x0c,0x9a,

0x66),"libopencoremkvsplitterrecognizer.so"
And now the problem is ;-) i can see in the trace log that is my
lib was loaded, but none method has been called. Why?

}//end of case OMX_PortSettingsChanged
Here if you see it gets the parameter from audio decode node which in turn
calls the decoder component layer
After geting the values it sets its own value.
But what I need is that I want to get the values from WAV Parser and set the
same to decoder component layer
Because In my case the WAV Parser is the one which has the proper info which I
want to Pass it on to decoder layer.
How can I do that.
