android - Illegal State Exception when calling MediaCodec.configure()

Question

I get the IllegalStateException on MediaCodec.configure() line, I'm trying to record audio using MediaCodec. This only occur on some phones, on tabs everything is fine. This particular crash example is from Samsung Galaxy S4. Exception traces:

Audio format declaration:

    MediaFormat format = new MediaFormat();
    format.setString(MediaFormat.KEY_MIME, "audio/mp4a-latm");
    format.setInteger(MediaFormat.KEY_AAC_PROFILE, MediaCodecInfo.CodecProfileLevel.AACObjectLC);
    format.setInteger(MediaFormat.KEY_SAMPLE_RATE, 44100);
    format.setInteger(MediaFormat.KEY_CHANNEL_COUNT, 1);
    format.setInteger(MediaFormat.KEY_BIT_RATE, 64000);

Audio encoder initialization:

        mAudioEncoder = MediaCodec.createEncoderByType("audio/mp4a-latm");
        mAudioEncoder.configure(mAudioFormat, null, null, MediaCodec.CONFIGURE_FLAG_ENCODE); //<-This line fails
        mAudioEncoder.start();

Does anyone have any idea what that might be? What's strange is that it only happens on some devices. Any suggestions would be welcome!

I see this same error when trying to configure a video codec on certain Samsung devices running Jellybean (4.1.2). In many cases, setting KEY_MAX_INPUT_SIZE to 0 (before calling configure) in the format parameters will fix it:

mVideoFormat.setInteger(MediaFormat.KEY_MAX_INPUT_SIZE, 0);

I found this solution when researching a similar bug (https://stackoverflow.com/questions/15105843/mediacodec-jelly-bean#=), and have been surprised at how many codec configuration bugs this fixes. That said, I haven't tried it on Audio codecs so no guarantee it will work in your case :/
