libstagefright - Experimental hardware video decoding builds
(2013-02-23, 09:00)fun_ Wrote: is it impossible to use local native window which has MOD32 surface instead of the native window returned from g_xbmcapp.GetAndroidVideoWindow()?

I think metadata of input stream is correct and no need to *fix* it. only MOD32 surface is required to output frames from hardware.
We don't use a "real" surface, but a SurfaceTexture, which wraps a GL texture.
Behind the scenes, GraphicBuffers are used, which are HW buffers that the HW decoder fills with a decoded frame. On top of those, one EGLImageKHR is mapped to each native window buffer.
"SurfaceTexture::updateTexImage" just maps the latest EGLImageKHR to the GL texture.

Fact is, on the other platforms, if there is a MODxx tweak, the frame size metadata reflects this and all is well.
On rk3066, the returned frame size is not MODxx and I assume this (wrong) frame size is used to build the EGLImage -> crashes.
So, really, for this to work on rk3066, the HW buffers size should be MODxx.

Note that using SW renderer, i.e. libstagefright thumbnail mode, just crashes the mediaserver/vpu:
