I recently obtained android ffmpeg decoding. The following describes the process for your reference.
1. ffmpeg Transplantation
There are some articles on ffmpeg porting on the Internet. I tried it many times but finally generated libffmpeg. so is

In C #, we can see three types of forced-type conversions, such as casting to signed 32-bit integers, and you can find the following three ways:① (int) () ②convert.toint32 () ③int. Parse ()Three kinds of transformations can be common in some data,
In C #, what are the differences between (INT), int32.parse (), convert. toint32 (), and int32.tryparse?
The Int keyword indicates an integer that is 32-bit. Its. NET Framework type is system. int32.If int32.tryparse () does not throw an exception,
In C #, what are the differences between (INT), int32.parse () and convert. toint32?
The Int keyword indicates an integer that is 32-bit. Its. NET Framework type is system. int32.
(INT) indicates explicit forced conversion, which is a type
The Int keyword indicates an integer that is 32-bit. Its. NET Framework type is system. int32.
(INT) indicates explicit forced conversion, which is a type conversion. Implicit conversions can be used when we convert from int type to long, float,
The difference between implicit and explicit conversions and castsstring strtype = "123"; Object Objtype= (object) strtype;//can not, implicitly convert, want to explicitly convert string strType2 = (string) ObjType; Must be, explicit conversionint
In the process of program development, log is a widely used mechanism for recording program execution, which can be used for both program debugging and event recording in product operations. The Android system provides a simple, convenient log
When developing Android applications, you must use Log to monitor and debug program execution. In the previous article on Android Log system driver Logger source code analysis, we analyzed the source code of the driver Logger. in the previous
Int32.parse (), convert. toint32 (), int32.tryparse ()The int keyword indicates an integer that is 32-bit. Its. net framework type is system. int32.If int32.tryparse () does not throw an exception, true or false is returned to indicate whether the

Any type can be safely converted to its base class type, which can be completed by implicit conversion;
Display conversion is required when any type is converted to its derived type. conversion
In the process of program development, log is a widely used mechanism used to record program execution processes. It can be used for program debugging or product Operation Event Recording. The Android system provides a simple and convenient Log
Android Close LogWhen we develop, we often output various logs to debug the code. But wait until the app release apk runs without expecting it to output the log.Turn off output log log.v (), LOG.I (), LOG.W (), LOG.V (), LOG.E (), etc.Principle:Then

Android disabled logs
During development, we often output various logs to debug code. However, when the application publishes an apk, it does not want to output logs.
Disable output logs such as Log. v (), Log. I (), Log. w (), Log. v (), and Log.
Eight sorting algorithms in the Data Structure
I. Bubble Sorting
Thought: I repeatedly visited the sequence to be sorted and compared two elements at a time. If their order is wrong, I will exchange them. The smallest elements come at a time,
