Decode:
(English):sync with the encode,can decode the 2kbps .hvx stream very perfect.
the command is "HVXCDecode.exe HE_test_originalC_hvxc2.hvx HE_test_originalC_hvxc2.au"
but can't decode the 4kbps stream, the reason is decode need the config information such as the bitrate mode,vbr or  cbr, scalable or not and er mode (follow the HVXC standard).
those config is include the fifth byte of the hvx file, this byte can't be support in the encoder, encoder will set the fifth a constant value.
v1.4 和编码器同步，能够完美解码2000bps的.hvx码流。命令行格式如下“HVXCDecode.exe HE_test_originalC_hvxc2.hvx HE_test_originalC_hvxc2.au”
但是不能解码4000bps码流，原因是，解码器要获得编码的配置信息，例如比特率模式，变码率还是定码率，是不是可分级，和er模式，参见HVXC标准。
这些配置信息应该在hvx文件的第五个字节提取，这个字节应该是在编码器写入的。这个字节的同步还没有做。编解码都没有做。
