Static calls in C # C++dll and C # in dynamic call C++dllIn recent projects, involving the project source code security issues, because the code is written in C #, easy to be anti-compilation, so decided to extract the core algorithm is written in C + +, C + + so far seems not to be very good anti-compilation, of course, if you are an anti-assembly master, it may be possible to decompile. In this way, it involves invoking C # managed code with C + + u

ffmpeg using Syntaxffmpeg [[options]['-i ' input_file] ... {[options] output_file} ... If there is no input file, then AV Capture (only works under Linux, because the audio and video device is handled as a file handle under Linux) will work.

For the original input file, the format option may be required

This document records the FFmpeg-based video decoder on another Android platform. Unlike the decoder documented in the previous article, the decoder documented in this article no longer uses class libraries such as libavcodec.so, libavformat.so, and only uses a class library--libffmpeg.so. The source code for the video decoder C language comes from the simplest ffmpeg+sdl-based video player. The related con
