(The PAV (H265) is the audio and video compression and decompression protocol, is very different from H264/MPEG4
ZPAV (H265) algorithm is a wavelet, multi-level tree collection group, and generalized wavelets, mathematical morphology, wavelet, ...
ZPAV (H265) algorithm:
1, image and sound decomposition and synthesis: wavelet
2, image and sound processing: wavelet sub-band zero-crossing noise, target texture processing, speech processing
3, the rate control: wavelet subband entropy rate control
4, quantization and inverse quantization: Wavelet subband entropy quantization and inverse quantization
5, the dimensionality reduction of the low frequency component and high frequency components: the wavelet subbands neighborhood cross-dimensionality reduction
6, the decomposition and synthesis of the motion vector and quantization tables: generalized wavelet

GZIP解压例子
利用gzip.dll解压http请求返回的内容。内附gzip.dll。参考网上资料自己写的VB6工程源码。自己编译EXE的时候注意把gzip.dll释放到exe所在目录。(Use gzip.dll to decompress the content returned by HTTP request. Gzip.dll is attached. Refer to the VB6 project source code written by myself.)
