Android :: How To Keep Receiving Wave Buffers Of Currently Playing Media
Apr 8, 2010
I can't seem to find the proper audio source for recording/analyzing/receiving the currently played music track (or just any playing media). I'm not talking about the Mic.
The spectrum live wallpaper does this on the Nexus One AFAIK.
How can I keep receiving wave buffers of the currently playing media?
(I would like to support everything from 1.5, but 2.1 specific solutions are also welcome)

I noticed that you can't adjust media volume without first playing media. Like you have to, for example, press the play button before pressing rocker volume in order to adjust media volume or else you'll just be adjusting ringer volume. This is unfortunate since games also use media volume. So if you wonna start up a quick game in a quiet setting, your in trouble if you were listening music before and never turned down/off the media volume. Unless I'm missing something and there is in fact a way to do it?

I just started with creating my own media player application by looking at the code samples given in Android SDK. While I am trying to play a local media file (m.3gp), I am getting IOException error :: error(1,-4).
package com.mediaPlayer;
import java.io.IOException;
import android.app.Activity;
import android.app.AlertDialog;
import android.content.DialogInterface;
import android.os.Bundle;...........

I had an Ipod touch and just sold it because I got an Eris. I really like the phone but the media player is lame compared to ipods. I listen to downloaded radio talk shows and if I stop and listen to another song, it doesn't save my place. Not horrible in a talk show but in an audiobook, it really sucks. I don't want an iphone if it comes to verizon but I also don't want to have to keep track of two devices. Does anyone know if there is a bookmark capable app for media playing or will there be in the future? Thanks. I did search and didn't find anything on this, so if I missed it somewhere, sorry.

I'm trying to play a playlist I get using the MediaStore provider. However, when I try playing a playlist nothing happens. Can a MediaPlayer play a playlist (m3u file) and do I need to set the first track to play? This is my test code in the onCreate() method:
Uri uri = MediaStore.Audio.Playlists.EXTERNAL_CONTENT_URI;
if(uri == null) { Log.e("Uri = null");
} String[] projection = new String[] { MediaStore.Audio.Playlists._ID,
MediaStore.Audio.Playlists.NAME, MediaStore.Audio.Playlists.DATA };
Cursor c = managedQuery(uri, projection, null, null, null);
if(c == null) { Toast.makeText(getApplicationContext(),
R.string.alarm_tone_picker_error, Toast.LENGTH_LONG).show();
return; } if(!c.moveToFirst()) { c.close();
Toast.makeText(getApplicationContext(), R.string.alarm_tone_picker_no_music,
Toast.LENGTH_LONG).show(); return; } c.moveToFirst(); try {
MediaPlayer player = new MediaPlayer(); player.setDataSource(c.getString(2));
player.start(); } catch(Exception e) { e.printStackTrace(); }
I have turned on every volume stream.

Did anyone try playing audio/video through http/rtsp. I am having a problem with either of the approach.... I am getting an error Command PLAYER_INIT completed with PVMFError I some cases I got Command PLAYER_INIT completed with PVMFErrorContentInvalidForProgressiveDownoload.

I have some pretty simple Soundboard applications on the Android Market that work flawless on an LG Ally, the Motorola Droid, and the Nexus One, but I recently received an e-mail from a user with the Motorola DroidX claiming that most of the sounds do not work. I've exchanged a few e-mails with him. He claims the Soundboard is the only application running, and he's double checked to make sure that the Media Volume wasn't set to minimum. I really don't have access to one either to play around with. The application isn't doing anything cosmic to play the sounds. Below is a code snippet. Any insights into what might be causing the hang up are greatly appreciated.
public void play(Sample sample) {
Log.v(TAG, "Playing: " + getString(sample.getButtonTextResId()) + " (" + sample.getSoundResId() + ")");
if (mPlayer != null) { mPlayer.stop(); mPlayer.release();
} MediaPlayer player = MediaPlayer.create(this, sample.getSoundResId());
mPlayer = player; if (player != null) { player.setVolume(1.0f, 1.0f);
player.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
@Override public void onCompletion(MediaPlayer mp) { mp.release();
mPlayer = null; } } ); player.start(); } }

In my android game I want to have a rhythm Mediaplayer object and a lead Mediaplayer object playing in sync. However at the moment the rhythm is a slight bit behind the playback of the lead Mediaplayer object. Is there a way I can make it so that both are started at the same time, for instance using Runnables etc?!It's quite crucial that they play in sync with each other as you can imagine!

I have a couple of MP4 videos that used to play on my HTC Desire before it got its Froyo uodate, that dont appear to be now. When I click on it to play, it comes up Cannot Play Video - Sorry, this video cannot be played. When I look at the details it has Type : Video/mp4 Am I doing something stupidly wrong? Also is there an easy piece of software that can copy DVDs into a format my Desire will understand. I'm after an ease of use rather than cheap bit of software.

We're currently launching a site with live (TV) and non-live streaming of video material.
The RTSP live feeds play fine on Android (.sdp extension) however other videos published on the side in MP4 format - don't. Neither the browser nor the Meridian player recognise the files and play them.
Any ideas where we went wrong?
PS. I'm not the guy in charge of the video encoding etc. but I'm looking for some tips and information for our team.

In a process of switching from indirect to direct buffers for OpenGL geometry specification I've found a problem with the following function in java.nio.IntBuffer class: IntBuffer put(int[] src, int off, int len) this function is supposed to do a bulk transfer of int data from the given array starting at the specified offset. It should be an optimized version of the following code: for (int i = 0; i < len; i++) {buffer.put(src[off + i]);}

I'm using MediaRecorder.setOutputFile(FileDescriptor fd) over a UNIX socket, so that local code on the device can see the encoded stream in real time (for video streaming out).
What I observed is that the encoder doesn't write encoded frames continuously, when they are produced, but by "bursts", exactly one second apart. I tried both containers (THREE_GPP and MPEG_4) and all three available codecs (MPEG_4_SP, H263, H264), the behavior is always the same. This one-second period is notably unrelated to framerate or bitrate, so it is not flushing by size; rather, it seems to be flushing by time (possibly to mask SD card write overheads ? Bummer, I 'm not using the SD here !). Is it a known limitation ? Is there a known workaround ?

When using Protocol Buffers with Android (running in the Windows VM) I'm noticing that the first time I instantiate a protocol buffer based class Android lags for some time. When I step through it looks like it's spending a lot of time dynamically loading the protocol buffer classes. Is there something I can do to speed up this process? I haven't tested yet on a physical device, so the delay might not be as bad but in the VM it takes about 30 - 45 seconds to load all the classes and get past that first message instantiation. What I did was downloaded the Protocol Buffers source code. Compiled the.java files. Stuffed them into a .jar. Added the .jar as an external library to my Eclipse project. Generated the .java classes from the .proto files. Added the generated .java files to my project. Ran my project. I'm not sure if I'm doing something wrong it terms of how to reference external libraries with an Android project, but 30-45 seconds seems like a very long time to wait on a 2.6GHz machine. Also, I recently learned that android uses Protocol Buffers internally. Will this cause any sort of conflicts with my included .jar that could be the problem? I *think* the namespace is different but I'm not entirely sure. Lastly. Why did Google use Protocol Buffers internally and not make it available to SDK developers. This makes me very sad knowing that it's all right there and I can't use it.

Liking the phone but the video playback is driving me nuts. I transfer Mp4s to the SD card, a new folder called Video and the phone sees them but only plays the audio. These Mp4s all work on my iPod Touch so is there something not right about them for Android? ie do they need reconverting?
They all have .mp4 as extensions and I have tried having the new video file on it's own on the SD card as well as trying it in the DCIM folder as suggested on another forum. Cheers for any help as I'm thinking this is all too much of a faff and I will have to get the iPhone. Shame as the HTC deal with Orange is very cheap.

for all those gl*Pointer functions you need to create bytebuffers through ByteBuffer.allocatedirect. when you want to load a texture through glteximage2d you need to supply a bytebuffer, too. can this be a "normal" bytebuffer or do I have to create this one too via allocatedirect?

I have HTC Desire with Android 2.1 and Windows 7 Premium 32bit. I have created some 3GP videos on the HTC and can play these successfully. When I transfer the file to Windows 7 the playback via Windows Media play doesn't have any sound. Same files playback with volume via iTunes. I'd really like to use these files with Windows Media Player. Is this some sort of codec issue? Why are such task seemingly simple tasks made so difficult?

I need to know if there is a way for watching .WMV videos on the HTC Hero.
I already know that it will play MPEG-4 videos without a problem (you can use the RealPlayer Video Downloader to download HQ/HD videos from places like Youtube and it automatically saves them to MPEG-4 format).
However, I want to transfer some files like music videos onto my HTC Hero and having tried several times, using the RealPlayer Converter, to convert the .mpg files to .wmv, I can't watch them on the Hero.
However, I recently looked at one of the threads (I think on a different forum) and he said that he could watch videos in WMV format using 750kbps on resolution 480x320. But RealPlayer only allows for 768kbps and resolution as 480p HD as the nearest possible (which was the setting I ordinarily chose).
The other strange thing is that when I go onto the Albums part of the phone to see if I can view any videos, it shows a thumbnail image of the music video (a preview image of the video) and when I play it, I can hear the music, but the video itself fails to appear.
