setDataSource Failed

[yumweb]

Hi Kevin,

Thanks for this module. It has been quite easier to use than the other libraries. Although, I have been facing some issues when recording using options on Android. I am not sure if this issue is specific to me or a bug in general. Recording works perfectly fine if no options are passed; but when any options are passed the app throws an error.

Below is the code that I am trying to use passing the additional source and format options. With the source set to SoundRecorder.VOICE_CALL I am basically trying to record the call conversation.

if (data.callState == 0) {
    SoundRecorder.start('/storage/emulated/0/Music/test.mp4', {
            source: SoundRecorder.VOICE_CALL,
            format: SoundRecorder.FORMAT_MPEG_4
        })
        .then(function() {
            console.log('started recording');
        });
} else if (data.callState !== 1) {
    SoundRecorder.stop()
        .then(function(path) {
            console.log('stopped recording, audio file saved at: ' + JSON.stringify(path));
        });
}

I get the following error at the time of stopping the recording. A corrupted file is saved to the location specified.

Here is the screenshot from the app

Will appreciate your help!

Which option is actually causing the error? source or format?

[yumweb]

Any of the option throws this error. I tried them both together and individually as well

[kevinresol]

The error is thrown when the library tries to read the recorded file, to get the duration. Since you said the output file is corrupted, I think that's why the error is thrown.

Now the problem gets to why the recorder can't produce the correct file.

I suggest debugging by making sure the parameters passed to the Media Recorder are valid e.g. setOutputFormat()

[yumweb]

Let me check that.

Will SoundRecorder.VOICE_CALL require additional permissions?

[kevinresol]

I'm not sure. Btw I think it should be SoundRecorder.SOURCE_VOICE_CALL

[yumweb]

Oops! That's right. Will change it and re-check. Thanks!

[yumweb]

Okay. I think I figured it out. There is a problem with SoundRecorder.SOURCE_VOICE_CALL

This source does not work with all devices. Some manufacturers disable this and can't be used. Ref: https://developer.android.com/reference/android/media/MediaRecorder.AudioSource.html#VOICE_CALL

Closing this issue for now. Thanks!

This fix occurs on stop:

Try to put this

try { retriever.setDataSource(mOutput); } catch (Exception e) { promise.reject("stopping_failed" , "Stop failed " + e); return; }

This catch the error and solve the issue!
