Hi guys.
You have to set several meta value for use MediaCodec Encoder.
Encoder need width, hegith,
bitrate(KEY_BIT_RATE<http://developer.android.com/reference/android/media/MediaFormat.html#KEY_BIT_RATE>
),
frame-rate(KEY_FRAME_RATE<http://developer.android.com/reference/android/media/MediaFormat.html#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.
