anybody run the new sunxi-cedarx lib successfully?

[kimdou]

i donload the sunxi-cedarx from https://github.com/allwinner-zh/media-codec/tree/master/sunxi-cedarx/SOURCE for A20
and i dont know whether this is the right flow to compile the library:
1. ./bootstrap
2. ./configure --prefix=/home/test/ --host=arm-linux-gnueabihf (im not sure the parameter is ok or not)
3. make && make install

then so file generated, then run demo in sunxi-cedarx/demo/vencoder on A20 board, then tell me segment fault...
it's strange that there is no code to call VEncoderRegister function in Venc_device.c.
