Disabling Screen Break with subsequent Preference Screens through XML.
Hi, I need to display another PreferenceScreen through xml which occupies the full screen. Calling addPrefrencesFromResource(id) with different id results in Screen Break handled by Preference Framework. setPreferenceScreen(mPS) could be called again & it works fine but it is through code...How do I do it through XML? Neither inflateFromResource() not PreferenceInflater is available so, I can't use setPreferenceScreen for XML? Plz do clarify. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "android-framework" group.

REG: Xml to Wbxml using EAS
Dear friends, I need to convert from Xml to Wbxml for Client-Server Communication using AirSynC (Microsoft Exchange Active Sync Protocol). I found XML to WBXML parsers available in ../dalvik/libcore/xml/src/ main/java/org/kxml2 but there was no official documentation regarding these apis. Inbuilt Google IM Application available in ../packages/apps/IM makes use of separate XML<-->WBXML parsers instead of using existing org.kxml2 package listed above and makes use of Native call for SynCML Tag Table mapping. My doubts are as follows: 1. Why ../dalvik/libcore/xml/src/main/java/org/kxml2 docs aren’t available, is it still in development stage? 2. Why Inbuilt IM Application has gone for Native Code and own Parsers instead of using ../dalvik/libcore/xml/src/main/java/org/kxml2 apis? 3. In ../dalvik/libcore/xml/src/main/java/org/ package, Support for SynCML, WV & WML. Could I get the sample Codes using these apis? Once I get the sample for SyncML , I need to change the XML<-->WBXML mapping based on AirSync(EAS) instead of XML.

Re: How to send a message or call a function written in audio decoder node from PlayerEngine?
I guess I still don't understand what type of control do you require for your decoder. In the most generic case of a multimedia framework, one would want only minimum control of a central entity, in this case the pvPlayer engine. The player engine in this case has the responsibility of controlling the underlying components, including the OMX Audio decoder node. Is it possible to expose these interfaces out, yes. But then the application developer would have to handle 100s of APIs to enable a single playback session. Note that there are some cases when such an interaction is convenient. For such cases, we do provide extension interfaces (e.g., look at authordriver.cpp for encoder extension interfaces) but with limited capability. Again, this may change in the future where we may provide the flexibility to the user to control this using some APIs of the engine itself. So, in short, the control to the underlying nodes will not be exposed. If you want to control your decoder from the node, it must be an OMX API implementation. What API(s) do you want to call? What is the purpose? We can discuss options if you spell out your usecase. -Ravi On Jun 12, 12:33 am, saxoappeal wrote: > Dear Ravi: > > Thank you Ravi, I think that you are a one of the most active and > smart engineers in the gourps. > I have seen your name on so many times, so many articles. > Anyway, > > Ravi: > What function(s) do you want to call from the decoder node? > > - the function written in the decoder source in /omx/omx_mp3 folder > from the PVMFOXMAudioDecNode. > > Ravi: > The interface is through OMX IL.

Re: How to send a message or call a function written in audio decoder node from PlayerEngine?
What function(s) do you want to call from the decoder node? The interface is through OMX IL. If you integrate your component (decoder) correctly, there shouldn't be a need to modify the client (node). -Ravi On Jun 11, 8:32 pm, saxoappeal wrote: > Hi All > > I have written my customized mp3 decoder in codecs/omx/omx_mp3. > So, I found a way to send a message to decoder from audiodec_node in > node. > > now, I need to know how to call a functions in the decoder from node > or PlayerEngine. > I have read the sources hundreds times, I only get the > PVMFNodeInteface in the Engine. > But, Every tries I had failed. and I have no idea and I am crying... > > It's maybe a kind of stupid question..but I really want to know it. > Please help me... > > Thanks. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "android-framework" group.

Re: creating custom MIO
You can query the engine for the format type after the ->AddDataSource () command completes. So, for your usecase, you need to add code in playerdriver to use the new API that we introduced in there, called getFormatType(), to get the format type of the content used in "AddDataSource()". You would do this just before "AddDataSink()" so that you can make a decision on which MIO to use. -Ravi On Jun 10, 4:04 am, manish wrote: > Let me re-phrase the question. > How can we find out that file format is aac or mp3 before creating > audiosink node in playerdriver > PV engine seems to know File formats "after" source and sink nodes > have been created, a little too late.

Re: Question about music player in Opencore 2.04
OpenCORE does not have a direct dependency on any keys on the physical/ virtual keyboard. That being said, applications can react to certain key events and take action accordingly.

Re: pmem usage in opencore of Android1.5
Yes. Only "fd" and "offset" are sent to the MIO. Regarding where the MemHeapBase is constructed, it could be vendor specific implementation.

Re: Recognizer plugins are not getting executed when I run .mp4 file playback use case
Which test application are you using? (i) pvplayer_engine_test, or
(ii) a mediaplayer test, or (iii) your own test app?
(i) As I mentioned earlier, this test app. guesses the format type
based on the file extension. So, a .mp4 file is set the format type
accordingly. If you want to force the "recognition", rename the file
extension to .xyz.
(ii) If you have proper logs, it should definitely show up.
(iii) Good luck.

Re: How to get traces from the pvmi\recognizer\plugins\pvmp4ffrecognizer\src files
Are you using the pvplayer_engine_test app. or the android media player? If pvplayer_engine_test, the test app. assigns the format type of the content being used based on the file extension. So, there is no recognition. If you want to force it, you can just rename the file as test.xyz (i.e., an invalid extension). If android media player, I don't know. Since you already have the logs from the other components, maybe you can figure it out. -Ravi On Jun 8, 4:42 am, Devaraj wrote: > Hi, > > I have added some prints like the below: > > PVLOGGER_LOGMSG(PVLOGMSG_INST_LLDBG, iLogger, PVLOGMSG_STACK_TRACE, > (0, "PVMP4FFRecognizerPlugin::GetRequiredMinBytesForRecognition() IN > \n")); > > in the file pvmp4ffrec_plugin.cpp. I am not getting these traces when > I run the MP4 video file where as I am getting the traces from other > module source files. what may be the reason? > > Thanks and Regards, > -Devaraj --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "android-framework" group.

Re: Can't generated video thumbnails in Android 1.5
In this mode, the parsers look for the best sync sample from the first 10 sync samples. "Best" here is defined as the biggest frame in terms of bytes with the rationale that an I-frame with more number of bytes will have more pictorial information compared to the others. So, first and foremost, you need to check how many I-frames is your encoder producing, if any? If there are I-frames, look at the mp4 parser node to see why you are not seeing any thumbnail. Or, file a bug, along with the clip in question, and we can take a look. -Ravi On Jun 8, 1:41 am, Jia Meng wrote: > I found there is a macro "BEST_THUMBNAIL_MODE" defined in > metadriver.h.

Re: Access Opencore engine through JNI
It is not advisable to bypass "mediaplayer" to reach directly PVPlayer class. There won't be any guarantee that your app. (and your JNI layer) will be compatible for future use cases. OpenCORE can technically be instantiated as thread-safe. However, in the current version, it has not yet been done. So, there is a playerdriver level which queues all commands from various threads to a single thread. -Ravi On Jun 5, 10:40 pm, allstars wrote: > hello world > i would like to use some API in opencore/sonivox > but these API aren't included in libmediaplayerservice ,nor > android.media > > so i would like to add my JNI to construct a PVPlayer like the > libmediaplayerservice did > is this ok? > i mean is it thread-safe in opencore engine > > i found i need to modify a lot files if i need to go through libmedia/ > libmediaplayerservice > for example IMlediaPlayer, IMediaPlayerService, etc. > > thanks --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "android-framework" group.

Re: encoder support in OpenCORE/cupcake
Let me try to summarize the many questions that I so far received in this context: OpenCORE 1.0 on master had the author engine working with the non-OMX codecs as well. On Cupcake, this is not the case. Cupcake has an OMX node that supports mpeg-4 OMX video component (in this case, the HW OMX component). But, if the HW component is not present, it is expected to pick the non-OMX SW codec. This functionality is missing.

Re: amr-wb codec in .3gp file format
What happens if you push a new mp4 file? Can you see the file doing "adb shell ls -l /sdcard" ? For the file to be detected, did you try restarting the emulator? For new formats to be detected by the mediascanner, you need to start from frameworks/base/media/java/android/media/MediaFile.java.

Re: amr-wb codec in .3gp file format
When was the last time you did your "repo sync"? When you "push" the content, do you see any error? Are you sure the sdcard is working for any other application?

I do see the GPL license. That's bizarre. I was under the impression that the entire android tree has to be provided with the Apache license. Maybe someone from Google can confirm.

Re: Regarding Audio/Video sink in Opencore framework.
>From what I understand, the OP wants to write test cases to the OpenCORE codebase that is provided from opensource. But, the attempt is to write testcases using the media player API. That is not possible. If one wants to write test cases to the OpenCORE framework, they have to use the opensource version. We have ample examples that show how test cases can be written. If one is using the SDK release, they have to use the existing media player APIs (provided only in JAVA).

Re: Regarding Audio/Video sink in Opencore framework.
Please read the documentation at opencore/doc/ pvplayer_developers_guide.pdf. This provides the high-level description of the PV architecture. OpenCORE is a native level code. If you are using the "SDK release", you cannot write test cases for our code. You have to use the "media player" java level APIs.

Re: amr-wb codec in .3gp file format
I don't know enough about QCELP to comment on how and if to modify the mp4 parser. I can try to find out. In general, the steps to add a new OMX codec would be: (i) Add the required format, if not present, in pvmi/pvmf/include/ pvmf_format_type.h. (ii) Add the mime type in the capability of PVMFOMXAudioDecNode() or PVMFOMXVideoDecNode() [see the constructor]. if you are going to use the OpenCORE OMX-core ... (iii) Register the component in the omx registry - codecs_v2/omx/ omx_common/src/pv_omxregistry.cpp. or if you are going to provide your own OMX-core ... (iii) Have your OMX-core register this new component. (iv) Have your OMX-core dynamically loadable. Not sure about your build failures. Can you post snippets of failures?

Re: What are those branches other than "master"
Example: http://android.git.kernel.org/?p=platform/bionic.git;a=heads It shows master, cupcake, donut, etc. as the heads or branch names. -Ravi On Apr 14, 10:40 pm, John Cola wrote: > Hi all > Waht are those branches other than master? > I only know cupcake, are there anyother else? > > BR > John --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "android-framework" group.
