[android-developers] Re: Most accurate method of using SoundPool
You can't get good timing from SoundPool. If you're talking about a music application where a few msecs of jitter affects the musical feel, you're going to need to mix your own streams to get the timing accuracy. We are planning on adding an API in a future release for music applications, probably something along the lines of a lightweight ASIO for mobile devices.

[android-developers] Re: SoundPool working correctly yet?
SoundPool issues were fixed in Cupcake. The fixes were dependent on other changes to the audio system and it was considered too risky to port those fixes back to the 1.x branch. We haven't released a Cupcake SDK yet. Other have had success with SoundPool by setting the maxStreams to a large value. This avoids the most egregious deadlock issue, although there are other issues that may result in ANR's depending on your use case. It also requires that you do your own stream management.

AsyncPlayer is just a helper class on top of MediaPlayer. It is not going to help you with gapless playback. I can see how the statement Plays a series of audio URIs is causing confusion.

[android-developers] Re: How to force MediaStore to rescan the SD card
I'm not sure about the process of removing a file from the database. I
suggest looking at the Music Player source - it has an option to
delete files from the SD card.
Under what circumstances would files be deleted without mounting and
re-mounting the SD card? That sounds like a poorly behaved app.

Now what if media files are deleted?
What if I do not know which ones have been deleted?
Is there a way to have it rescan the entire SD card in the
way it must do if the card has been removed and reinserted?

You might be able to get away with recording the mic - I haven't checked. I'm pretty sure if you change the sample rate to something other than 8KHz, it will kill uplink audio.

[android-developers] Re: How to use AsyncPlayer ()??? Uri?
I think your confusion probably comes from the phrase plays a series of audio URI's. AudioSyncPlayert's just a simple helper class for playing audio files that runs on its own thread, instead of on the UI thread. The first time you call play, it will start playing a sound. If you call it a second time while the first sound is playing, it will stop the first sound and start playing the second one. It's not really usable for a music player if that's what you hand in mind. On Feb 16, 5:31 pm, Moto medicalsou...@gmail.com wrote: Hi all! I'm a little way too confused using the AsyncPlayer class.

You can also add some logging to your code.

Then scatter log statements around the code in various places:

[android-developers] Re: Is VideoView Broken?
You can't play a resource file using VideoView by passing a pathname. The file doesn't exist; it's just a binary blob inside the APK file. If you create a content provider, you could pass a URI to setVideo(). I'm not entirely sure that will work because the video file might be compressed inside the APK. We exclude audio files from compression, but I don't video files are excluded because they don't make a lot of sense as a resource - they are too big. The simplest way to get this working is to copy the file to the SD card. You can either adb push the file to the SD card or UMS mount the SD card and copy it over from your host computer. Then modify your setVideo(path) to /sdcard/movie.mp4 (or whatever directory you put it in on the SD card).

[android-developers] Re: What's in raw data from PictureCallback of camera?
I think we'll be able to give you something that will meet your needs. It's always a balancing act between taking the time to get the API just right and getting a product to market. Keep making suggestions, we are listening. On Feb 11, 4:08 am, blindfold seeingwithso...@gmail.com wrote: Thank you David, I feel relieved to hear that. :-) Rather than trying to do all your image processing in Java, wouldn't you prefer to have built-in native signal processing kernels that are optimized for the platform? Yes, of course. One can parameterize and wrap under an API a number of useful low-level image (and audio) operations, such as various filtering operations, edge detection, corner detection, segmentation, convolution and so on. That is certainly very nice to have, but not enough. I would want to implement my own pixel-level (and audio-byte- level) processing algorithms that do not fit within the pre-canned categories, while benefiting from the platform and CPU independence of Android (no JNI if I can avoid it). It would be purely computational code with loops and conditional branches, operating on arrays, array elements and scalars. At that level, C code (minus any pointering) and Java code actually looks almost the same. No real need for any fancy data structures etc at *that* level that then covers the expensive parts of the processing, so I feel that a simple, light-weight, targeted JIT compiler could come a long way to meeting all these needs: I really would not mind if it would only compile a (computational) subset of Java, and it may leave code optimizations to the developer by compiling rather straightforwardly. (Cannot help being reminded of FORTRAN-77 on old IBM mainframes getting compiled almost 1-to-1 to easy-to-read machine code.) So perhaps rather than a built-in native signal processing *kernel* I am here thinking of a built-in native signal processing (JIT) *compiler*. ;-) Regards On Feb 11, 11:03 am, Dave Sparks davidspa...@android.com wrote: I'm talking about deprecating the raw picture callback that has never worked.

[android-developers] Re: Playing video in android
First, the surface type needs to be push buffers. In your Preview
constructor, add the following:
getHolder().setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
Second, you need to tell the media player where to display the video.
You have a line commented out:
//mp.setDisplay(mPreview.getHolder().getSurface());
It should look like this:
mp.setDisplay(mPreview.getHolder());
If you get stuck, take a look at the VideoView.java widget source code
on android.git.kernel.org. It's in the frameworks/base project at core/
java/widget/VideoView.java

[android-developers] Re: Native code is not supported in the current SDK.
Further clarification: I was under the impression it is possible to download the java source code AND the C source code and build them all. It is possible to download the open source code and build for the emulator. If you want the code to run on a specific device, you need additional libraries that are not necessarily available in open source. These libraries are provided by the manufacturer and/or third party vendors and contain hardware specific code. If its not possible does it just mean its not possible for 3rd party developers to do but it is possible for device manufacturers to do? Manufacturers do write native code to adapt Android to their hardware in order to create these device specific libraries. This code is usually exposed through a hardware abstraction layer that hides the eccentricities of the device from the application developer. We do intend to support native code development in the future. We just want to take time to refine the native API's before we make them public. There is nothing more painful than changing an API because you overlooked something and then having to support the legacy API for years to come. On Feb 5, 10:57 am, Jean-Baptiste Queru j...@android.com wrote: it is possible to make it work for a given device running a given revision of the software. It is not currently possible to make it work in a way that behaves predictably on different devices or different revisions of the software (including, importantly, devices or software revisions that haven't been released yet). That's why it's not supported: if you make it work on your device right now and it doesn't work in another environment, you shouldn't expect to receive any help or to see any effort spent at the framework level to try to make your application work in the future. The same is true of undocumented classes, functions, or parameter values.

This is not a scenario we can support today. You can get close by decrypting the stream, writing it to a file in your application's private directory, and playing it from there. This would keep it reasonably secure unless the phone is jail-broken. Of course, it's not real-time streaming - you need to write out the complete file first.

What kind of plug-in do you want to write? media player is kind of a vague term. There is the Music player application, the MusicPlaybackService, the MovieView activity, the VideoView activity, and the MediaPlayer object. Source for all of those is available at source.android.com.

From the debug spew from the audio input driver, it sounds like it
should be recording. Do you see the file being written to the SD card?

[android-developers] Re: gapless playback
Yes, two reasons actually. One, because the Ogg spec allows for specifying the exact number of samples in the stream. MP3 does not have an official way to specify the number of samples (there are unofficial ways). Two, because the Ogg player has a native loop capability that allows us to seamlessly loop at the exact sample boundary. OpenCore does not support seamless loops, we have to explicitly seek to the beginning of the file in loop mode. Thus any streams that are rendered by OpenCore (i.e. everything but Ogg and MIDI) will have gaps.

You shouldn't have to reboot the device. The release() call just forces the release of the hardware resources instead of waiting for the garbage collector to come along.

[android-developers] Re: android audio
In SDK 1.0, you can only record to a file using the AMR-NB codec, which is bandwidth limited to 4KHz, and the encoding process itself is pretty lossy. If you want to experiment with this on a G1, go to Messaging, create a new message, click menu and select Attach, and select Record Audio. This will take you to the Sound Recorder activity where you can record and playback audio to get an idea of the audio quality.

[android-developers] Re: MediaPlayer seeking back
I believe the OpenCore HTTP streaming engine maintains a circular buffer of data. As data is played out, the buffer space it occupied is re-filled with new data. When you seek backwards in the stream, it has to re-fill the buffer from the earlier part of the stream. On Jan 29, 1:05 pm, ed edwin.fuq...@gmail.com wrote: I've been using androids MediaPlayer to stream from an http url and have a question about seeking. Currently, our urls expire after they have been used once or a certain time out has expired to dissuade scraping content. Now, this obviously makes progressive streaming past the buffer impossible with the exact same url as you need to open a new http connection with the same mangled key, which we intentionally don't allow. However, MediaPlayer seems to do this when seeking before the current position (i.e. seeking from 1:00 in the audio to 0:30). As the file has already been downloaded up to the current position I'm confused as to why MediaPlayer is still trying to initate a new http connection in this case? The only thing I can think of is that MediaPlayer is getting rid of audio its already played up to the current position, and hence needs to restart the connection if you try to seek back on the stream. Is this correct, or is there something else going on? Thanks, Ed --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Simultaneous Photography using Andriod
The simplest approach is just firing off an intent to the existing camera app to take a picture. This requires the user to push the shutter button. If you want it purely under program control, you could have the application snap the picture without the user pressing a button. It just takes a bit more work.

[android-developers] Re: Reg playing youtube video in android
If you specifically want to play a YouTube video, you need to register as a YouTube developer to get the keys you need to access the Gdata feeds. I think that the Cupcake release will support a new intent for playing YouTube videos with the YouTube app, but it will be some time before that feature makes it into an SDK or actual device. That would remove the need for getting the developer keys. Aside from that, playing a YT video is no different than any other HTTP streamed video. You just pass the URL through setDataSource and the media player does the rest.

[android-developers] Re: android.hardware.Camera - JPEG image of correct size but always black
By contract, apps are supposed to release the camera in onPause(). Failing to do so could result in the battery draining quickly because we have the DSP and sensor hardware spun up. The problem that the current design choice introduces is that the camera can be in the middle of any operation when another app steals it away. There is no mechanism for returning the camera to a known state or even querying the state so that appropriate steps can be taken to get it to the right state. On Jan 23, 9:39 am, Dianne Hackborn hack...@android.com wrote: The locking is done that way because as you move through the UI the next activity receiving focus should be the one to get the camera, as soon as it comes up. Otherwise if you switch from one activity using the camera directly to another using the camera, the new one won't be able to access it because the previous one has not yet had a chance to close it.

[android-developers] Re: android.hardware.Camera - JPEG image of correct size but always black
Right now, the answer is no. Most cameras require that you go to preview mode before you can take a picture so that the image processor can grab some frames for auto-focus, white balance, etc. I'll see if we can get a change into Cupcake that allows you to start preview without a surface. That should allow you to do what you want. It will be some time though before this feature will appear on devices in the field. The other thing you need to bear in mind is that the camera eats a LOT of power. You don't want to run it for long periods of time in background. I forget what the power numbers are on the G1, but I bet when if kept fully spun-up it will drain the battery in a couple of hours.

[android-developers] Re: Camera Focus Facility
Roughly:
Camera mCamera = Camera.open();
// this sequence should occur after onResume and surfaceCreated
mCamera.setPreviewDisplay(mSurfaceHolder); // saved from
surfaceCreated call
mCamera.startPreview();
// to start focus - usally called from your onClickListener
mCamera.autoFocus(afCallback);
// to take picture - usually called from your onClick listener
mCamera.takePicture(shutterCallback, null, pictureCallback);
// auto focus callback
public void autoFocusCallback(boolean focused, Camera camera) {
// play focused sound
}
// shutter callback function
public void shutterCallback() {
// play shutter sound
}
// picture callback function
public void pictureCallback(byte rawData[], Camera camera) {
// save JPEG
}
You should also note that there is significant lag from the time
takePicture() is called until the image capture begins. You can
shorten this time by calling auto-focus first. You don't want to move
the camera until after the shutter callback.

What you want is coming in Cupcake. There is astreaminginterface

If you need something for SDK 1.0, there is a MediaRecorder function
called getMaxAmplitude(). You should be able to get what you want by
writing theaudiofile to /dev/null and calling into getMaxAmplitude
periodically. Take a look at the source code for SoundRecorder on

samples between ?
perhaps it is possible to use two recorders which toggle between
recording states ... when on is recording, the other is priming
and
waiting to record ...
Something like :
//declare two recorders
MediaRecorder recorder1 = new MediaRecorder();
MediaRecorder recorder2 = new MediaRecorder();
/// continuously prime, start and stop the two streams so one is
always capturing ...
//prime and start recorder1 - this is the loop roll in
recorder1.setAudioSource
recorder1.setOutputFormat
recorder1.setAudioEncoder
recorder1.setOutputFile
recorder1.prepare
recorder1.start
while (1){
//prime and start recording from recorder2
recorder2.setAudioSource
recorder2.setOutputFormat
recorder2.setAudioEncoder
recorder2.setOutputFile
recorder2.prepare
//wait a certain ammount of time to allow capture
sleep
recorder2.start
recorder1.stop
recorder1.reset
//prime recorder1
recorder1.setAudioSource
recorder1.setOutputFormat
recorder1.setAudioEncoder
recorder1.setOutputFile
recorder1.prepare
//wait a certain ammount of time to allow capture
sleep
/// switch recorders
recorder1.start
recorder2.stop
recorder2.reset
}
recorder1.release();
recorder2.release();

[android-developers] Re: Equalizer...
At this time, there is no mechanism to get at the raw audio after it is decoded.

We haven't released a Cupcake SDK yet. Docs will come when the SDK is published.

I am an audio/graphics professional and my first project, for kicks, is to port my desktop Java Quake3 class game engine to Android and OpenGL ES as a test of well my ability to get Q3 tech playing with ES and Android and it didn't take long to realize the state of audio in SDK 1.0_r1 is not suitable for lots of audio stuff I'd like to accomplish in general and some novel features for my port (IE voice chat with desktop clients from built in mic on G1, etc; fun!). We'll see how the Q3 port turns out; gonna hack a file based push to talk feature most likely via MediaRecorder; delayed audio w/ this though and only one way to desktop clients to show proof of concept. I specifically did not adopt or even look at Android until a handset device was released and the SDK hit 1.0 simply because I knew the platform probably would not be complete and I don't have the time / desire to work around incomplete APIs / implementation (yes, was correct on that; for audio at least; lots of gold to be had elsewhere; seriously, kudos Android team et al, I haven't been this excited in a while about a new tech!). So, yes, lets continue to discuss how to solve the audio issue that encroaches on all of us who want performance audio on Android and all 'droid devices in general. I will throw in my two cents on how I _am_ (not would be) solving it after dealing with the woes and inadequacies of Java Sound on the desktop _for years_ from an API perspective to simply incomplete implementations on various platforms and JVM versions. (Java Sound - Write once, test everywhe... oh wait you mean it doesn't fully work on X platform at all?.?. gah!!!) One solution on the desktop has been to ditch Java Sound andsupport PortAudio (www.portaudio.com) via JNI. I propose that Android can also provide the best and most _portable_ audio solution not only on the G1 and other devices, but _future_ hardware that supports Android by adopting PortAudio and exposing a lean and mean API to developers that then can be further extended with higher level APIs for purpose built processes (speech detection / Jspeex port / DSP processing, even a javax.soundimplementation built _on top_ of PortAudio, etc). What is needed is simple and efficient raw audio I/O functionality at the core; PortAudio provides this and only this! For file I/O it's not a bad idea tosupportLibsndfile (http://www.mega-nerd.com/libsndfile/). Between PortAudio Libsndfile raw hardware and file based audio I/O can be solved by time tested open source solutions. Now... I mentioned future hardware supporting Android... I just so happen to be developing an embedded audio hardware product that focuses on advanced spatial processing (think large scale 2D and 3D sound arrays; I have a 32 speaker hemisphere setup at my facility in SF for instance; check here for those interested in an overview I published for the recent AES conference in SF w/ picts equipment specifications --http://research.egrsoftware.com/conferences/2008/aes2008/) and after finally dipping into Android (IE G1 SDK 1.0 finally available and in my hands) I've decided unanimously and almost instantly to ditch my previous path which was Analog Devices Blackfin/ Sharc based processors running uClinux and am switching to the TI OMAP3 3550 and Android as the processor/stack. In doing this I already am adopting PortAudio on my future Android based hardware and this is how I presentlyplanto expose audio I/O to Android developers on my hardware. So in time this is _going_ to be done already. Seeing asthereisn't a published / unified vision on where to take audio I/O for Android as is I do
