This method has been verified by practice, is being used in the project, you can view later: http://www.0431net.com, the core function of the website video mode is to use this method to achieve fast :)

Convertthread class

Package com. v246.convertflv;

Public class convertthread extends thread {
 
Private string frompath = NULL;
Private string topath = NULL;
@ Override
Public void run (){
Convert. getinstance (). Convert (frompath, topath );
}
Public void setfrompath (string frompath ){
This. frompath = frompath;
}
Public void settopath (string topath ){
This. topath = topath;
}
}

 

Convertthreadproxy class:

Package com. v246.convertflv;

Public class convertthreadproxy {
Public static void convert (string frompath, string topath ){
Convertthread Ct = new convertthread ();
Ct. setfrompath (frompath );
Ct. settopath (topath );
Ct. Start ();
}
}

 

 

When using this function, you only need to use the static method of the convertthreadproxy class to set the absolute address of the Source Video (including the file name + display name) and the absolute address of the FLV file to be generated (including the file name + display name) it can be passed in as a string! Because multithreading is used, the conversion process does not occupy the current thread!

The core conversion class is thread-synchronous, so you don't have to worry about the parallel problem, because only one file can be converted at a time!

Note: install and use FFMPEG to convert the video to a FLV file (Windows and Linux)
Use a Java program to call FFMPEG to convert the video file format to FLV
