I am trying to develop an app which streams live audio/video. I have the mediarecorder to record both audio, video frames , and it does so. But the thing is it records a chunk of audio and then records a chunk of video frames and then records a chunk of audio frames to the file. How do I determine where my audio frames start and where the video frames start?. Also is there any way to figure out the Video frame length ?. Iam really stuck at this point and any help will be greatly appreciated. This is how I initialize the mediarecorder in my app, Code...

Such an awesome camera and camcorder but it sounds like I am speaking through a damn kazoo. I am dying to know if it's firmware or just cheap hardware, not to sound bitter but the iphone has a SUPER high quality mic being that Incredible just came out I was very surprised at the low quality of the audio recording
View 12 Replies View RelatedI'd like to create an audio recording in Android. (Actually, I just want access to the mic without recording it, but it seems that's not supported so I'll have to create a recording and tail the file). I'm having a very hard time getting started. Mostly I'm just hoping that someone from Google reads this and will update the documentation because the example won't compile - it looks like it's from some previous version of the SDK because there's an error in every other line. I made my best guess as to what the usage should be, but I keep getting a number of different exceptions. One question I had is whether I can just specify an arbitrary path to the MediaRecorder to start recording or whether I have to create an entry in the content database. The JavaDoc for MediaRecorder.setOutputFile isn't clear on what it's expecting.
View 19 Replies View RelatedI have a Java application where in I am trying to read Audio samples from the mic into a buffer and then write the samples back to speaker from a buffer for playing. I have used AudioRecord and AudioTrack interfaces. Below are my configurations for the Record and Track object creation. AudioTrack(0, 8000, 2, 2, playBufSize, 1); AudioRecord(1, 8000, 2, 2, recBufSize); Using AudioRecord interface I am able to read the samples from mic continiously (8000 sampling rate and 640 samples per read). In the similar way I am also able to write some pcm samples to the speaker from a buffer and play it continuously using the AudioTrack interface (without record). But when I try to do both record and play simultaneously I am able to only record audio from mic but I am not able to play any samples to speaker. I am getting this error " ------- attemp playback while recording, cheat it! ----- " in the log cat.
I have given the following permissions "android.permission.RECORD_AUDIO" and "android.permission.MODIFY_AUDIO_SETTINGS" in the Manifest file. I didn't find any special permission to play the audio. Is there anything else that I need to enable?
I am developing a recorder application It works fine with Microphone. I want to record from Bluetooth headset. I set it like

But it cant record from Bluetooth device. How to record from Bluetooth device.
I will describe briefly my trouble with audio recording.
So, I am doing audio recording using MediaRecorder, but unfortunately when I playback the recorded audio, I have media with a very low volume. I don't here anything (almost anything).
Is there any possibility to setup recording volume?
Im 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

Record audio using the native AudioRecord interface? I'm trying to do this on my Neo Freerunner but all I get in logcat is:
I/AudioHardwareALSA( 787): Initialized ALSA CAPTURE device AndroidRecord_Microphone
D/AudioHardwareALSA( 787): Set CAPTURE PCM format to S16_LE (Signed 16 bit Little Endian)
D/AudioHardwareALSA( 787): Using 1 channel for CAPTURE.
D/AudioHardwareALSA( 787): Set CAPTURE sample rate to 8000 HZ
E/AudioFlinger( 787): Error reading audio input
W/AudioRecord( 947): obtainBuffer timed out (is the CPU pegged?) user=00000000, server=00000000
The android::AudioRecord::read() function returns the number of bytes I'm trying to read, but the resulting buffer is filled with zeroes.

I tried screencast recorder, z screen recorder etc(to record video+audio then extract audio), but they all record audio from the microphone, so that didn't work out. is there a way to extract the audio from the game somehow, or some on screen audio recorder for android devices?
Is it only possible for one object to access the microphone at a time? That is, could I simultaneously use an AudioRecord to do some audio processing and use a MediaRecorder to record the incoming audio?
View 2 Replies View RelatedHey, I have a problem with android programing when I try to record and then play the file that was just recored. I can both record and play the sound but the quality stinks. Its not just bad is really hard to listen to and sound abit like its a computer generated voice. I use the andriod SDK-emulator. The code that sets up the recording looks like this;
MediaRecorder recorder = new MediaRecorder();
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setOutputFormat(MediaRecorder.OutputFormat.RAW_AMR);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setOutputFile(path);
recorder.prepare();
recorder.start();
And the code playing the file later looks like this;
MediaPlayer mp = new MediaPlayer(); mp.reset();
mp.setDataSource(path); mp.prepare(); mp.start();
I don't know what part that makes the audio file sound really bad or if its just the emulator that makes it bad and that it would work on a real phone.
AudioRecord can record audio data in pcm format in realtime, but there is no audio-encoder who can encode pcm data to amr format. may be third-party java code can do this, but the performance may be very low.MediaRecorder just record audio data to disk. not realtime.It seems that this is a real miss-impossible?
View 2 Replies View RelatedI'm writing an App that needs to continuously record audio in memory and email the last 30 seconds of audio when required.

If it does support then in which format and where is the example. Also I am trying to figure out MP3 encoding long ago but still no solution. I have recorded an audio ()which is in AMR by default, how can I convert it in MP3 (any external package I can use?)
Is the Evo supposed to be auto-focusing when its recording video? If I have just the viewfinder and no recording going on, it auto-focuses whatever I point it at, but when it comes to recording, its not auto-focusing at all. It just stays blurry.
View 1 Replies View RelatedDon't know if anyone knew this but if you download the LED Desire light from the app store, use the app first to leave the LED lights on and go to your video recorder. You can now record video in the dark and have somewhat clarity with the LED lights on. Granted it would probably be a big energy waster, but atleast you know have a choice.

Is there any way to pause the video recording function? I've looked all over the net and can't find an app or a reason why this feature seems to be missing from all Android phones.
This is HD recording and could potentially replace low end video units. Seems like it should be unnecessary to use an external video editor to get a vacation video in one piece.
From my understanding the Desire was originally supposed to have HD video recording, but this was ditched. Is it possible that a future firmware upgrade could allow HD recording, or the phone physically incapable of recording in HD?
