Does anybody know of a way to directly access the Video Encoders provided by the(android.media.MediaRecorder) API? I'd like to make changes to the raw camera data "before" it gets encoded.

When I add video source and video encoder, it gives error in recoreder.prepare() (prepare failed) while the same code is working only for audio. I am not finding what I am doing wrong.
setContentView(R.layout.camera);
preview=(SurfaceView)findViewById(R.id.surface);
previewHolder=preview.getHolder(); previewHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
recorder = new MediaRecorder();
String url = "/sdcard/dcim/test.3gp";
camera = Camera.open();
Camera.Parameters parameters = camera.getParameters();
parameters.setPreviewSize(352, 288);
parameters.set("orientation", "portrait");
camera.setParameters(parameters);
recorder.setAudioSource(MediaRecorder.AudioSource.MIC); recorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
recorder.setOutputFile(url);
recorder.setVideoFrameRate(15);
recorder.setVideoSize(480, 320);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB); recorder.setVideoEncoder(MediaRecorder.VideoEncoder.H263);
recorder.prepare(); recorder.start(); Thread.sleep(100000);
recorder.stop(); recorder.release();
} catch (Exception e) { e.getMessage(); }
I've been trying to develop an application for the android 1.5 sdk version that allows the user to simply recorder a video but it has been a long road. I can record audio with the simple example on the android developers website but when I put the VideoSource and the VideoEncoder lines it gives a 100 error that means that the Camera server died. Here is an example of the code.
recorder.setCamera(mCamera); recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP); recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setOutputFile("/sdcard/dcim/Camera/test.3gp");
recorder.setVideoEncoder(MediaRecorder.VideoEncoder.MPEG_4_SP);
recorder.prepare(); recorder.start(); ...
Here is the debug error messages:

First, I want to save the encoded video stream from the encoder,And then, the encoder recieves the uncompressed video stream from camera. How can my application recieve the compressed stream from the encoder?
Second, I'd like to add the custom composer engine to media framework(opencore), And then I'll use the already-launched device, HTC Hero and Motrola Droid, etc. The custom composer engine will recieve the video stream from the encoder. And, save the stream using the custom file format. Is it possible add the custome engine using the already-lauched device? If it is posselbe, where can I find the references?
Does anyone know of a direct api that allows access to CPU usage statistics for different applications/tasks running inside android? All I can find is data available by accessing a file "/proc/stat" but this seems a little cumbersome. ActivityManager holds data about processes/tasks etc but no CPU usage stats.

But since the examples I've seen all use content providers, I'm not sure how to proceed without them and populate activities with data derived from accessing my application's database directly.

information on direct access to GEARS geolocation functions from an Android application. To date, I have not found any. geolocation includes three Android-specific public Java classes, AndroidGpsLocationProvider, AndroidRadioLocationProvider, and AndroidWifiLocationProvider. The fact that they are Android-specific and that they are public lead me to conclude that I should be able to use these classes in my application. However, not surprisingly, when I try to access these classes, my application fails (see log below) because, among other things, I have no way to correctly identify nativeObject in the java classes. At the very least, I would like to understand the purpose of the three Android-specific public Java classes, and how we should use them.

I understand, at least on paper, the basic difference between the Content Provider and just directly accessing the SQLiteDatabase. I have a functioning prototype for my application, and currently it is just directly hitting the database. I don't really have any experience using the Content Provider pattern, but I have found out that I will need to share some data with another application.
I will only be sharing about 2 out of a dozen or so tables, so I was wondering if I should be just completely redoing the data layer to follow the Content Provider pattern, or just expose only those tables via a Content Provider for the sake of the other application and still directly access the database in the primary application.
One of the issues I ran into with my prototype was that I have some fairly complex transactions, and the code I wrote to get that working is not designed particularly well and isn't reusable at all. As I add more functionality to this app, I'm going to need a better designed data access layer, before I set off writing my own, does anyone know of any good resources with design patterns for this type of thing already? Also, if I need to go the Content Provider route, am I going to have solid control over the database transactions?

View 4 Replies View RelatedI've just published an app to Google Play. It is an app that allows people (mostly tourists) in my area to easily find businesses around them. One functionality that my app offers is to make a phone call to these companies by tapping a button in the app, including emergency numbers.
Google Play says that the app requires "direct phone access, it can call phone numbers without your intervention, which can lead to a high phone bill, but not emergency numbers". This doesn't completely fit my intention.
My app would work just fine if it had to ask the user every time it wanted to make a call, and it doesn't call anything when no buttons are tapped, plus I DO want the app to be able to call emergency numbers (with the user's consent off course).
I've used XDA many times before, normally for specific questions on ARHD ROMs.
I work on a cruise ship and we're continually crossing time zones. Currently, to alter the time zone on my (rooted) HTC OneX, I need to pull down the notifications tray, select settings, scroll down and select date and time, then select time zone. I can't use the Auto function, as the network time on the ship (satellite) is only available over Wi-Fi, for which I have to pay an exorbitant rate.
I'm looking for an app that will allow me one-tap access to changing the time zone. 'Time Zone Widget Light' almost does the job, as a tap on the widget scrolls through pre-set time zones, but this only allows me to step forward, and sometimes I need to go backwards as well (sadly our ship itineraries refuse to follow pre-set time zones, although I'm working on it!)

One thing I would like to do is create a on-click shortcut to search for nearby hardware stores (I'm a contractor and sometimes need to pickup task-specific materials). I could swear there used to be a shortcut available called "Direct Search" or something like that, that would do just what I'm looking for, but I don't see it when I try to add a shortcut to the home screen. Did this used to exist, or was it just my imagination? Is there anything like it now? I know I could make a bookmark in the browser and place a shortcut to the bookmark on the home screen, but I was hoping for the results to come up in Google Maps.

View 2 Replies View RelatedSo - I *love* Google Maps with Navigation and I just recently upgraded to the new version of maps where it gives you a direct link to Navigation. My issue though is that I do not have any voice navigation when I start Navigation directly but I do have it when I just go through the regular Maps link and then select Navigation in there. I checked the menu and it is not muted. The sounds is also set to high. As I said, the sound works perfectly well if I go through the main app. Just not with the new direct link. Anyone else seeing this or worked this out?
View 2 Replies View RelatedIm trying to record audio directly from the system. Using the standard API, you can only record from the MIC or phonecalls, ala: MediaRecorder.Some ways I've tried is to read from /dev/audio and /dev/eac from my app, but I think the sandbox of the app is preventing this.Im thinking about using the NDK, but Im not sure if that would overcome the sandbox aspect ? Ideally, there is some solution outthere to access the audio sub- system directly. Whether it be directly to alsa, to the AudioFlinger, to /dev/eac

From the documentation it is not clear that at which offset, calling the following method, will place the data: audiorecord.read(directbytebuffer, size);
Been getting a headache with some 2d Opengl coordinates and putting them in a direct buffer.
I have a basic square defined as such

This runs, no segfault or anything, and when I iterate through the buffer the size and values seem exactly the same (8 elements, ordered just as the array). What happens though is that my draw() function draws nothing, it works one way, but doesn't work the other way. I use Direct Buffers in a lot of my other geometry. I have to get direct buffers working or I know that my software might not be reliable.
