Android OpenGL ES plotting tutorial 3: Drawing GraphicsAfter defining the shapes to be drawn by OpenGL, you certainly want to draw them. Using OpenGL ES 2.0 to draw a graph may require more code than you think, because the API provides a large number of graphic rendering pipeline control interfaces.This chapter describes how to use OpenGL ES 2.0 API to draw the s
OpenGL es Shader language variables and data types (i) (Official document fourth)all variables and functions must be declared before they are used. Variables and function names are identifiers .Without a default type, all variables and function declarations must contain a claim type and an optional modifier. Variables are declared in the first place to indicate the type, followed by a number of variables, separated by commas. In many cases, a variable

es--elementary Streams (Raw Stream) is a data stream that comes directly from the encoder, so the encoded video data stream (H.264,mjpeg, etc.), audio data stream (AAC), or other encoded data stream is collectively referred to. After the ES stream passes through the PES packager, it is converted into a PES package.

After defining the shape to be drawn with OpenGL, you may want to draw them on the screen. Drawing these shapes based on OpenGL ES 2.0 requires a little more code than you think, because the 2.0 API provides a lot of control over the image rendering pipeline. This section describes how to use the OpenGL ES 2.0 API to draw the shape you have

TS Stream decoding process:
1. Get Pat in ts
2. Obtain PMT From ts
3. You can know the video (audio) type (h264), corresponding PID, and pcr pid transmitted in the current network based on PMT.
4. Set the video filter of the Demux module to the PID and stream type of the corresponding video.
5. the payload data in the ts data packet obtained from the video Demux filter is one piece of PES. The ts header contains the number of p

OpenGL has become a "standard" for 3D because it can be used across platforms and has rich interfaces. Almost all 3D games on mobile phones are related to OpenGL.
Of course, Microsoft has direct X, but it can only be used on the Microsoft platform.
OpenGL is implemented in c/c ++ at the underlying layer, and encapsulated class libraries are used in JAVA. Android provides the following interface packages to meet the r

Projection
The 2D plotting of OpenGL ES is mapped to the screen through "projection. We have already mentioned that OpenGL ES is mainly related to triangles. A triangle has three vertices in 3D space (remember that OpenGL ES performs operations on graphics in 3D space ). To draw such a triangle in framebuffer, OpenGL ES
