talk about what is intra-frame prediction and inter-frame prediction in the encoding process before understanding I-frame B-frame P-frames 1. Intra-frame predictive coding Intra-frame encoding is used to reduce spatial redundancy

In video compression, each frame represents a delicate image. In actual compression, various algorithms are used to reduce the data capacity. IPB is the most common one.To put it simply, I frame is a key frame and belongs to intra-frame compression. It is the same as avi compression. P indicates the forward search. B i

During video compression, each frame represents a static image. In actual compression, various algorithms are used to reduce the data capacity. IPB is the most common one. Intra coded frames,Predicted pictures, AndBi-directional predictive pictures. An I frame is a key frame and is compressed within a frame. It is the

Live555 + FFMPEG how to extract key frames (I frame, P frame, B frame)When developing a Streaming Media Player, especially on the Windows Mobile and Symbian (s60) platforms, you may need to develop your own player.The s60 platform provides the cvideoplayutility interface to implement streaming media players. However, because it is not open-source, many operations

From the simplest of an HTTP request development, according to the TCP/IP protocol, separate the data frame structure of each layer, and how they assume the network service.Protocol stackThe Internet protocol stack consists of five layers:1. The application layer is where the network application and its application layer protocols persist. The application layer of the Internet includes many protocols, common HTTP (which provides request and delivery f

Frame B has four reference modes in the MPEG-4. If both the image compression before and after the reference is recorded, the difference between the pixel value of the front image + pixel value of the back image)/2 is recorded, that is, the difference between the image and the average image. Therefore, the number of Difference values recorded is the same as that of P frames. There is only one difference, which is not increased. Because BThe

After iOS 9.0, Apple officially announced no longer or no recommendation to use Uialertview and uiactionsheet to be replaced by Uialertcontroller. It's easy to use a controller to combine the two. The following is a common method of Uialertview #import "RootViewController.h" @interface Rootviewcontroller () @end @implementation Rootviewcontroller -(void) Viewdidload { [Super Viewdidload]; Create a button click on the show Bomb frame UIButton *bu
