[android-developers] Re: java.lang.IllegalStateException in Media.configure() with the new MediaCodec API

Hi guys.

You have to set several meta value for use MediaCodec Encoder.

Encoder need width, hegith, bitrate(KEY_BIT_RATE), frame-rate(KEY_FRAME_RATE) keys value for configure.

MediaFormat mFormat = MediaFormat.createVideoFormat("video/avc",getWidth, getHeight);

mFormat.setInteger(KEY_BIT_RATE, value);

mFormat.setInteger(KEY_FRAME_RATE, value);

codec.configure( mFormat, null, null, MediaCodec.CONFIGURE_FLAG_ENCODE);

Thanks.

Lee.

Hi,

I have a strange issue regarding the new MediaCodec API on Jellybean.

The native function android.media.MediaCodec.native_configure is throwing a java.lang.IllegalStateException.

I'm using the OMX.TI.DUCATI1.VIDEO.H264E codec on a Galaxy Nexus (maguro).

Here is my Scala code:

class ScreenshotView(context: Context, attr: AttributeSet, style: Int)
extends SurfaceView(context, attr, style) with SurfaceHolder.Callback {
private def startEncoder = {
var surface = getHolder.getSurface
var codec: MediaCodec = MediaCodec.createEncoderByType("video/avc")
        codec.configure(MediaFormat.createVideoFormat("video/avc",
          getWidth, getHeight), surface, null, MediaCodec.CONFIGURE_FLAG_ENCODE)
    }
}

 

When calling the startEncoder method, the codec.configure() fails.

Here is what I can see in the logcat:

I/OMXClient( 1193): Using client-side OMX mux.
E/OHELP   ( 1193): CODEC:android.media.MediaCodec@42124b70

E/AndroidRuntime( 1193):        at android.media.MediaCodec.configure(MediaCodec.java:257)

If I'm looking at the JNI, here is where the exception is thrown (frameworks/base/media/jni/android_media_MediaCodec.cpp:338):

static jint throwExceptionAsNecessary(
        JNIEnv *env, status_t err, const char *msg = NULL) {
    if (err >= ERROR_DRM_WV_VENDOR_MIN && err <= ERROR_DRM_WV_VENDOR_MAX) {
        // We'll throw our custom MediaCodec.CryptoException
        throwCryptoException(env, err, msg);
        return 0;
    }
    switch (err) {
        case OK:
            return 0;
        case -EAGAIN:
            return DEQUEUE_INFO_TRY_AGAIN_LATER;
        case INFO_FORMAT_CHANGED:
            return DEQUEUE_INFO_OUTPUT_FORMAT_CHANGED;
        case INFO_OUTPUT_BUFFERS_CHANGED:
            return DEQUEUE_INFO_OUTPUT_BUFFERS_CHANGED;
        default:
        {
            jniThrowException(env, "java/lang/IllegalStateException", NULL);   /// I'm getting there                                     
            break;
        }
    }
    return 0;
}

This call is made in the last line of android_media_MediaCodec_native_configure() (line 389):

    err = codec->configure(format, surfaceTexture, crypto, flags);
    throwExceptionAsNecessary(env, err);                                                                            

Is there anything I'm doing wrong?

My surface is valid (isValid() is returning true). Everything passed to codec->configure() in the JNI seems to be ok too.

Any clues?

Thanks,
