I'm just trying to play a local video that is a resource with the MediaPlayer class in the most simple way possible. I have confirmed that the video works with players that I download from the marketplace, so I'm assuming that's not the issue.
The problem is that I just get a black screen with no video. There is audio from the file playing though, so I know that the file resource is being accessed correctly, it's just not showing anything on the screen in the emulator.
The one other note is that at any time whenever I try to access getVideoWidth() or getVideoHeight() I get this (non-blocking) error:
ERROR/MediaPlayerService(24): getVideoSize returned -1
Any ideas as to what I could be doing wrong?

My application cannot handle the JNIE overhead, as I need to make 2 JNIE calls to the native C/C++ code for every 20msec. So I am trying to use the native media libraries and the realted C/C++ files provided by Android in the folder "//external/srec/audio/test" of the donut build. Ex. AudioHardwareRecord, AudioInRecord etc.. I am implementing all the calls in the native layer.
I am using the sampling rate as 8000 and want to read 160 samples (320 bytes) at a time.
I used the following values to create the AudioRecord..
CODE:..........
It says "success" after creating this interface but I am getting the error "Bad Value" if I am doing the InitCheck.
And it is crashing once I start reading the samples or if I try to retrieve the configured sampling rate.
Has anybody tried to access this native code?
Does such a thing exist please folks - want to rip some audio for an mp3 ringtone from a comedy video clip

The HTC web site claims support for .mp4 and .wmv playback but I have had no luck. I have used various programs from HandBrake to Sony and I can get audio with no video (mp4). I can get audio with still image video (wmv). The DI seems very picky as to which videos it will actually play back. Is there a recommended way to convert my videos / DVS into a format the DI can play?
View 1 Replies View RelatedI am trying to play a file using the MediaPlay. The first time it is played, it only plays for 1 or 2 seconds then cuts out and never returns. The second time I play the song, it goes about 3 seconds. This function is in the onCreate function:
checkin.setOnCheckedChangeListener(new OnCheckedChangeListener(){
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked){
MediaPlayer mp = MediaPlayer.create(context, R.raw.my_song);
mp.start();
v.vibrate(500);
myLocation.getLocation(context, locationResult);}
Is another thread clearing overriding the song? How do I get my whole song to play?

View 11 Replies View RelatedI have a samsung galaxy s2 on AT&T running android 4.0.4. I have the bluetooth set up to play audio through my car stereo.
Everything was working fine until a couple of days ago when I accidentally booted my phone into safe mode. I re-booted it back into normal mode, but a lot of my settings got messed up after that happened.
The odd thing is that now, when I am in my car, the phone connects to the stereo over bluetooth - I see the name of the song, artist, etc information on the car stereo, and can do things like skip to the next song using the controls in the car. However, the sound actually plays through the phone speaker instead of the car speakers!
I've been trying to stream mp3's over http using Android's built in MediaPlayer class. The documentation would suggest to me that this should be as easy as :
MediaPlayer mp = new MediaPlayer();
mp.setDataSource(URL_OF_FILE);
mp.prepare();
mp.start();
However I am getting the following repeatedly. I have tried different URLs as well. Please don't tell me that streaming doesn't work on mp3's.

I am trying to make a very simple radio player for Android and I cannot get the audio streaming to work. In my latest attempt it plays for about 1 second and stops for some streams and it doesnt work at all for some other streams. Logcat doesn't give much useful information to me. I am testing on HTC Hero (Android 1.5).
If I hook the completion and buffer events I see the audio gets a complete event but it keeps buffering. Is there anything wrong with the code below? Should I be able to stream the the audio streams below? Is there a complete example somewhere of a working radio streaming?................
In my music app, i would like to play live streaming like radio broadcasting with mediaplayer as Mediaplayer mp = new Mediaplayer(); mp.setDataSource(LiveStreamingURL); mp.prepare(); mp.start(); but after playing for few seconds it is stopped. I dont know how to overcome it. Give me your suggestions for this.
View 3 Replies View RelatedI want to create an Android application that is a client for an Internet radio station. And I want it look native to Android? But im confused with Android API logic and documentation. What i've got is that I need MediaPlayer and MediaController classes. Am I right, and is there any good example of AUDIO player for Android?
Especially, I'm very interested how to use MediaPlayer and MediaController classes together.
UPD:
Finally I've got the code, that does exactly what I want:

I'm trying to create a way to adjust volume settings for each of the different streams (media, notification, ringtone, etc) and have a way to preview the output sound level of each stream. I believe I have the correct implementation, but when I set the output stream type, there is no sound that plays.
Here is the code that correctly plays the user's selected alarm sound:
CODE:.................
That commented out line is what is causing me problems. I would like to hear the alarm sound at the volume levels of the different audio streams, but when I include that line for STREAM_ALARM or any other audio stream, no sound at all plays.
Some audio files return 0 from MediaPlayer.getDuration(), even though they're perfectly valid files that play ok and that players on Windows can find the duration of. There seem to be two different cases here: certain file types such as .wma and .wav always return 0 duration, and others only do so sometimes. I haven't been able to find any pattern in the latter case, but it does seem consistent per file. The music player displays 0:00 duration for these, so it's not just my code.
View 3 Replies View RelatedI am having the following problem: I am using Android's MediaPlayer to play an mp3 through an HTTP connection. The audio is played correctly, but the MediaPlayer returns an incorrect duration (calling mediaPlayer.getDuration() ). Depending on the mp3 the duration is either shorter or longer. The code that plays the audio is the following:
mediaPlayer = new MediaPlayer(); mediaPlayer.setOnCompletionListener(this); mediaPlayer.setOnErrorListener(this); mediaPlayer.setOnPreparedListener(this); mediaPlayer.setOnBufferingUpdateListener(this); mediaPlayer.setDataSource("a valid URL"); mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC); mediaPlayer.prepareAsync();............................
Is it now possible mit sdk1.6 the audio decoder to access/use without using MediaPlayer ?
I saw : New version of OpenCore
Android 1.6 includes the updated OpenCore 2 media engine, which has:
* Support for OpenMAX encoders* Support for additional audio codecs in AuthorEngine* Improved buffering model supports shared buffers allocated in the decoder. but dont know how!
I have a activity which is called from another activity as an intent... This activity loads and starts playing a audio file. All is good - that much works. The activity also has a "stop" button and that stops the audio from playing - that is also fine.
But how do I stop the file from playing if the user uses the back button to leave the activity without clicking on the "Stop" button?
I am streaming an MP3 audio and instead making this MP3 audio to play, I want it to be converted to PCM format and pass this PCM audio to AudioTrack(as it takes PCM data as input.) instead of passing my MP3 stream to MediaPlayer. Can anyone please help me to convert the MP3 to PCM stream?
