视频抠像的演示。其中Ball是由SDK的一个例子修改而来，增加了 属性页，可以定制输出图像的尺寸，注意Filter的注册名改为“Bouncing Ball plus”；FilterVideoKeyer是一个实现了抠像叠加的Filter，这个Filter有两个 输入Pin，一个输出Pin，Filter的注册名为“HQ Video Keyer”。-like to pull the video demonstration. Ball which is an example of the SDK adapted from increased property pages can customize the output image size, the attention Filter registered name was changed to "Bouncing Ball plus"; FilterVideoKeyer is achieved keying a superposition of Filter, Filter has two input Pin, an output Pin, Filter the registration called "HQ Video Keyer."

G721-G723　源代码 G.726 is an ITU-T ADPCM speech codec standard covering the transmission of voice at rates of 16, 24, 32, and 40 kbit/s. It was introduced to supersede both G.721, which covered ADPCM at 32 kbit/s, and G.723, which described ADPCM for 24 and 40 kbit/s. G.726 also introduced a new 16 kbit/s rate. The four bit rates associated with G.726 are often referred to by the bit size of a sample, which are 2-bits, 3-bits, 4-bits, and 5-bits respectively.-G721-G723 source code of G.726 is an ITU-T ADPCM speech codec standard covering the transmission of voice at rates of 16, 24, 32, and 40 kbit/s.
