MediaCodec as decoder to send decoded data to two surfaces. How can we avoid big trunk data copy?

To configure a decoder, we call

decoder.configure(format,surface, crypto,flags).

And then, in

MediaCodec.Callback.onOutputBufferAvailable(),

we call

codec.releaseOutputBuffer(index,System.nanoTime())

to draw the decoded video on that surface which is passed in configure() function. Do we have a way to send that output buffer to another surface which is created by an encoder from

MediaCodec.createInputSurface()

to avoid big trunk data copy.

There is no way to do that. After taking look into Nvidia Android source code and omx decoder implement; if we need to send data into two surfaces, we have to use native DMA memory copy functions from manufacturer, or using native omx decoder directly.
