I am writing an application where I want to be able to capture video. I am trying to use the MediaRecorder API in 1.5, which is supposed to support video capture. However, there are no examples in the documentation on how to use this API for video (only for audio, and that works perfect). Basically what I do is the following: final MediaRecorder recorder = new MediaRecorder(); final String filePath; recorder.setAudioSource(MediaRecorder.AudioSource.MIC); recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP); recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB); recorder.setVideoSource(MediaRecorder.VideoSource.CAMERA); recorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4); recorder.setVideoEncoder(MediaRecorder.VideoEncoder.MPEG_4_SP); recorder.setOutputFile(filePath); recorder.prepare(); recorder.start(); This gives me the following error: E/CameraInput( 37): No surface is available for display E/MediaRecorder( 7609): prepare failed: -2147483648 OK, so I have to have a surface to preview the video? Could be useful I guess, but not something I really need. Could I use the VideoView widget for this, or is that only for playback? Or am I supposed to use a SurfaceView to preview the video? I saw someone use that to capture images, but they used android.hardware.Camera to open the camera and capture a frame, and did not use MediaRecorder. Does anyone have any idea on how to capture video, or even better have some example code?

Google Voice Search is a Google application, not part of the Android

license agreement.
However, because it uses the intent system, it is possible for someone
else to provide competing solution.

Hi,
I have a requirement to play several sounds many times in my game so
instead of creating the MediaPlayer again and again I have called
mp.seekTo(0) in onCompletion(mp) so that it will restart.
Sometimes the sound is not audible from the device when I call mp.start
() after setting mp.seekTo(0); but the player calls onCompletion()
without playing any sound, this is observed randomly on most of the
sounds
FYI:
- My sounds are of short duration mostly less than a second.
- I am using a separate MediaPlayer for each sound (as I need this)
- There are almost 28 sounds in my game so i will be creating 28
MediaPlayers.
- Below is the attached code for player
Also If I try to play many sounds one after the other in a short
period of time i get an error saying no more track names available.

return;

try {

[android-developers] Re: Error playing YouTube video in my application
I assume this in the emulator. I believe the issue is that the
emulator does not forward the UDP packets you need for the RTP
session. This should work on a real device.

[android-developers] Re: AudioRecord can't get any notification when record/marker position updated
OK, so it sounds like audio is being produced by the kernel driver.
I just looked at your code, and I think you need to call read() once
to pass in your first input buffer.

[android-developers] Re: SDK1.5 AudioRecord sample rate problem
I believe this is a known limitation of the emulator. There is a feature request to allow for more sample rates, but no one is actively working on it. The source code is available if someone wants to take it on. On Apr 25, 2:36 pm, szabolcs szabolcs.vr...@gmail.com wrote: Dave, Yoni, Thank you for replying. Is this on the emulator? If so, it may be a limitation of the emulator. Yes, I experienced the problem using the 1.5 prerelease SDK emulator. I dont know how the G1 would behave. Make sure you're using 16 bit samples.. I have tried pretty much ALL permutations of the different parameters, including PCM_16BIT, with no DEFAULTS. Still, Recording works only with a sample rate of 8000Hz. From now on I will assume its an issue with the pre release 1.5 emulator that will get fixed into the final version. Dave, is it enough that you know about this issue, or am I supposed to fill out a bugreport somewhere?

Use SoundPool.

I have other problem now. Lets say I have 10 buttons (0-9), when user
press button program should play short (0.3-0.5 secs) sound. I added
them as wav resources. Now I see that each MediaPlayer creates its own
thread and takes resources. I'm not sure that this is good idea to
make 10 players. But if I create player when user presses button it
works fine only if user presses no more than 1 button in 2 secs. If
user presses button each second or even several buttons a second, some
sounds are silent. What's best solution for this problem on android?
On Pocket PC we can play wav files fast - we create thread, that uses
WaveIO and we have no silent sounds. How can we make sounds ready to
play fast?

Hello.
I have this task:
Need to play short (0.3-0.4 sec) sounds all the time. When sound is
played, it should start again, etc. User can press button to reset
sound - it should stop and lunch.
I did many tests. I tried to create 1 MediaPlayer, then do this:
MediaPlayer.OnCompletionListener complListener = new
MediaPlayer.OnCompletionListener()
{
public void onCompletion(MediaPlayer mp) {
lunchSound(); // rewind
}
};
private boolean lunchSound()
{
try
{
mplayer.seekTo(0); // move to start
mplayer.start();
return true;
}catch(Exception e){}
return false;
}
When user press button, I call lunchSound();
It works great on emulator and on device if I have eclipse+debugger
on.
When I disconnect debugger, I have very strange errors - sound can
stop at all (till program restart), sound can start repeating (play
0.1-0.2 sec, then restart). Can someone please provide me some info
about problem?
Thanks.

But android.media.AudioFormat provides only 8-bit PCM and 16- bit PCM options, no AMR-NB option for some reason. I have also looked into MediaRecorder class. My understanding is that while MediaRecorder supprots recording to AMR-NB format, MediaRecorder can only write to a file (not to a network stream). It seems I need to use the AudioRecord class but it doesn't seem to support AMR-NB. Please shed some light!

I'm not clear what you mean by full size. VideoView displays as large as possible without distorting the aspect ratio. For all releases through Cupcake, we assume the display is HVGA. If videois to fill the screen, it must be 1.333 aspect ratio. For CIF or QCIF format, the aspect ratio is 1.222. To maintain correct aspect ratio, there are bars along the sides of the video.

The native code was throwing IOException even in 1.0, but it wasn't a

another application or service has control of the camera.

Camera.setPreviewDisplay() now throws an IOException. Is there a reason this

The consequence is that one cannot have code that will compile for both 1.1

dummy throw like:
try {
mCamera.setPreviewDisplay(holder);
if (false) throw new IOException();} catch (IOException e) {

[android-developers] Re: ERROR/MediaPlayer(1066): setDataSource called in state 128
MediaPlayer states are protected by mutexes in the native layer. However, the playback complete is an asynchronous event that comes on a binder worker thread. It's possible that you could call reset() in the window after the native media player service has posted a playback complete message to the binder interface, but before the client worker thread has processed it. In this case, the playback complete message would reset the client side of the interface to the stopped state. Your subsequent setDataSource() call would fail. If you wait for the playback complete message and then post a message to your handler to start the next playback, you can avoid this problem. Or as Marco suggests, create a second MediaPlayer object. Just make sure you call release() on each one after you're done with it to release the native resources. On Apr 9, 8:23 pm, ATrubka atru...@gmail.com wrote: I agree that it's most likely me doing something wrong. It looks like when the audio file is about to end the state of MediaPlayer gets changed in the native code. And maybe reset() doesn't take effect during this process while setDataSource(), invoked right after, finds player not to be ready. Maybe Android music app creates MediaPlayer every time or synchronizes the invocations somehow. I wonder whether the situation I described is possible and if it is whether you can advise on the solution. I can create MediaPlayer all the time, but I'm afraid to use too many resources doing so. I'm usually reluctant to creation of unnecessary objects. I really appreciate your help and apologize for my not very deep knowledge of the player functionality. On Apr 9, 3:23 pm, Marco Nelissen marc...@android.com wrote: I am one, and the error you posted indicates you called setDataSource while the MediaPlayer was in the 'playback completed' state. It could be a race condition in the framework, but since I have never seen this problem occur with the Android music app, I'm inclined to think it's a problem with your code.

[android-developers] Re: Why does not SoundRecoder work on G1
OpenCORE has no support for MP3 or QCELP encoding at this time, so those are not options.

[android-developers] Re: MediaPlayer sluggish to play sounds
Agreed. It takes about 100 msecs to spin up the audio output once it
goes to standby. You will seeing something like this in the log:
W/AudioFlinger( 35): write blocked for 103 msecs
If it's taking several seconds, there must be something else involved.

Do you have the same issue when playing a file in the music player, for
example?
On Tue, Mar 31, 2009 at 5:35 PM, Eric M. Burke burke.e...@gmail.com wrote:
I have an Activity that plays a brief OGG pop sound effect when
bubbles pop. To keep it fast and to ensure I can play several pops, I
create four MediaPlayer instances. I synchronize access to a pool of
instances, so I can play up to four pops at once. Once a sound
completes, I call seekTo(0) and return the MediaPlayer instance to my
pool.
Here is a rough sketch of the code:
// when the activity resumes...
for (int i=0; i4; i++) {
MediaPlayer mp = MediaPlayer.create(context, R.raw.pop);
mp.setOnCompletionListener(this);
mp.setVolume(1f, 1f);
players.add(mp); // put into a pool of available players
}
// when a bubble pops...
MediaPlayer mp = ...get player instance from the pool
if (mp != null) {
mp.start(); // works! plays the pop sound
}
// implement the OnCompletionListener interface
public void onCompletion(MediaPlayer mp) {
// seek to the start so I can play the sound fast the next time
mp.seekTo(0);
return the MediaPlayer to the pool
}
Here is the problem. The pops all work so long as my game is active.
But if I let it sit there for just a few seconds, I see this in the
LogCat console: (on my G1 phone)
AudioHardwareMSM72xx Going to standby
Once this happens, the next several calls to MediaPlayer's start()
method play nothing...but they do cause the audio hardware to wake up
again, so then my sounds eventually (after a few seconds) start
playing again.
My question is, how do I prevent the AudioHardwareMSM72xx from going
to standby mode while my Activity is active?
One hacky idea...I could loop a continuous sound at extremely low
volume level in another MediaPlayer instance to force it to stay
awake. That's not appealing to me.
Ideas?

Additionally, the gallery/camera apps only create the mini version of the thumbnail and not the micro version. It would be great to have a clear, consistent policy for thumbnail generation of images that reside on the SD card. I can foresee apps battling over thumb creation, some doing it well, others not so well and using different (custom?) sizes for both sizes. That's my two cents.

[android-developers] Re: Plan for setParameter in AudioManager.java
You should be asking this question in android-framework - this list is
for application developers.
However, the short answer is that we are removing this API in the next
major release. In fact, the entire audio architecture is going to get
a new treatment.
We are planning on a replacement for setParameter/getParameter that
will support atomic commits. So, if you do decide to use setParameter
now, it should not be difficult to merge your changes when the new API
is in place. I would prefer that you go this way over modifying the
binder interface and all the JNI. In fact, that's precisely why we
will continue to provide an API like this so you don' t have to worry
about mucking with binder code.

On Wed, Feb 18, 2009 at 1:08 AM, Dave Sparks davidspa...@android.comwrote:
This code shouldn't even compile, this line is wrong:
mCamera.takePicture(null, mPictureCallback); // requires 3 callback
functions
Camera is only supported in landscape mode. Cupcake release will
unofficially support portrait mode (there will be no API for it, but
I'll probably put some sample code out that shows how to do it).

1 It only can take picture in Landscape orientation
2 After click the space key, the application crashes. WOw:)

Please don't handle the volume keys yourself - it is almost impossible to guarantee that you won't break the behavior of the volume keys.

[android-developers] Re: URGENT - video playing problem
The H.264 codec in the G1 is baseline profile Level 1.3. Maximum frame size is 480x320 (happily the same dimensions as the screen). Recommended maximum bit rate is 384Kbps. Maximum frame rate is 30 fps. It does not support B-frames (consistent with baseline profile). If you stay within these bounds, you should have good performance. That said, with a good encoder, you can push the bit rate a bit higher. The important thing is that it not be too bursty, the decoder can handle a few frames at double the bit rate, but eventually it will fall behind. I've even had the audio track screw up when I pushed it too hard.

Hello I am trying to take picture by G1 camera.
I have tried almost everything i was able to find on the net about
this topic. It seams there should be intent with action
android.media.action.IMAGE_CAPTURE which really starts camera
application and returns captured image. But captured image is scaled
to 0.25 of original size.
Another possibility I have found is to pass uri where to save captured
image. I went through all available sources of camera application and
it should work but does not.
For illustration, I am doing following in my example activity which
creates new image, but after returning from camera, image is still
empty:
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ContentValues values = new ContentValues();
values.put(Media.TITLE, Image);
values.put(Media.DESCRIPTION, Image capture by camera);
Uri uri =
getContentResolver().insert(Media.EXTERNAL_CONTENT_URI, values);
Intent i = new Intent(android.media.action.IMAGE_CAPTURE);
i.putExtra(output, uri);
startActivityForResult(i, 1);
}
I am ready to write my own capturing application, but it is quite hard
and I would like to reuse.
Please, do you know correct intent action name and extra name to pass
to capture image?
Thank you very much.
