1. ffmepg Structure Description1.1 IntroductionFFmpeg (Fast Forward Moving Pictures ExpertsGroup) is a complete solution for audio and video separation, conversion, encoding and decoding, and streaming media. The most important solution is the libavcodec library, which is a set of recording, conversion, audio/video encoding and decoding functions.A complete open-source solution. FFmpeg is developed based on

Ffmpeg simple video player and ffmpeg player
Refer to Lei Xiaohua's simplest FFMPEG-based video player.
There is always a problem when porting code to my linux environment, So I simply analyzed and transplanted Raytheon's code for debugging from start to end.
Development Environment:

The overall call logic is:1. Compile the FFMPEG Library2. Use JNI to write C code, which must contain the corresponding FFMPEG header file3. Write the corresponding Android. mk file, which specifies the C code to be compiled and the dynamic library to be linked.4. Execute ndk-build to generate the corresponding JNI Library5. Create the andorid Java program. The corresponding
