MediaRecorder randomly fails to work #546

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
I'm an android developer and I developed a application to use MediaRecorder to 
record voice. It used to work well when my milestone is still with android 2.1 
version.

Recently I flashed the Rom CM 7.1 RC3 for my milestone. But I frequently failed 
to record voice by my application.

I checked the logs, found the followings(just part of them):
05-18 19:14:21.663: WARN/IMediaDeathNotifier(18711): media server died
05-18 19:14:21.663: INFO/ServiceManager(1399): service 'media.audio_flinger' 
died

05-18 19:14:21.702: WARN/AudioSystem(1715): AudioPolicyService server died!

I have no idea why these "servers" died. I did nothing special, just click a 
button to start record.

However, it will work successfully sometimes, just for luck.
So I suppose it's due to the problem about bottom implement of hardware or 
driver level of the CM7 rom. Could anyone please help me explain this strange 
issue?

Thanks,
Timmy

I need to see the log of what happened before the mediaserver died. What you 
posted is happening to late and the actual cause of the death is not there.

Here is my logic to record voice:

            mRecorder = new MediaRecorder();
            mRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
                       mRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
            mRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
            mRecorder.setOutputFile(strAudioPath);
            mRecorder.setOnErrorListener(errorListener);
            mRecorder.setOnInfoListener(infoListener);
            try {
                mRecorder.prepare();
                mRecorder.start();
            } catch (IllegalStateException e) {
                Log.e("MediaRecorder",e.toString());
                e.printStackTrace();
            } catch (IOException e) {
                Log.e("MediaRecorder",e.toString());
                e.printStackTrace();
            }

It's very strange that there is nothing in the log about the reason of the 
media server death.
Nevertheless, the exception handling in your code does not seem to me right.
Look how it is done in SoundRecorder:
https://github.com/CyanogenMod/android_packages_apps_SoundRecorder/blob/gingerbr
ead/src/com/android/soundrecorder/Recorder.java#L146
I haven't experienced any failure when testing the recording in the 
SoundRecorder app.

I replace my exception handling part with these according to SoundRecorder:

            // Handle IOException
            try {
                mRecorder.prepare();
            } catch(IOException exception) {
                Log.i("MediaRecorder", "INTERNAL_ERROR");
                mRecorder.reset();
                mRecorder.release();
                mRecorder = null;
                return;
            }
            // Handle RuntimeException if the recording couldn't start
            try {
                mRecorder.start();
            } catch (RuntimeException exception) {
                AudioManager audioMngr = (AudioManager)context.getSystemService(Context.AUDIO_SERVICE);
                boolean isInCall = audioMngr.getMode() == AudioManager.MODE_IN_CALL;
                Log.i("MediaRecorder", String.valueOf(isInCall));
                mRecorder.reset();
                mRecorder.release();
                mRecorder = null;
                return;
            }

However, the problem still exists.
What's more, I find that the two exceptions seem never to be fired as there 
isn't any log tagged "MediaRecorder" when media servers died.
So I think the problem is not happened when recorder is prepare() or start(). 
The media server just died inexplicably. Really weird.

Isn't there something relevant even more early in the log?

The log I posted is from the moment I click the button to start till I click a 
button to stop. I think it's quite simple.

I just find a more interesting thing. The camera doesn't work, either.

Intent it = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(it, 10);

This is a very general way to call camera to take a picture and get the picture 
back.
It used to work well. Now when it calls up camera and I click the camera button 
to take a photo, the "Insert" or "OK" button will never show, just a "Cancel" 
button.

I check the log, find that "media server died" again.

Log is too long, please refer to the attachment. (pay attention to the lines 
from 05-19 00:44:47.561):
