Media Processing.
Media Handler Pro 5.0 introduce generalized function that can be used to perform any level of media processing task. You can use this function to process any level of ffmpeg commands covering almost all needs: video conversion, sound extraction, encoding file for iPod or PSP, and more.
View below list of some practicle examples for using "Process()" function in your .net applications (c#, vb.net, asp.net) to achieve any level of video processing tasks.
Sample Code using "Process()" Method. (C# only)
Note: It requires Media Handler Pro 5.0 or later
