Dump the contents of a .rm file to a text file. This is known as a dump operation. Add meta information to the file that is specific to your application Obtain information on the types of streams contained in the .rm file Obtain the size of the video image Determine whether a .rm file is single rate or SureStream. SureStream is a technology by which RealMedia files achieve the following Creates one file for all connection rate environments Switches to different streams based on link speed. The Entire SDK centers on the concept of Encoding.
Lets see how it works.
The general encoding process consists of converting an input data source of one format into an output of a different format. The role of the RealProducer SDK is to provide the encoding engine that takes various media input and produces output in the RealMedia format. The working of the encoding session can be put into blocks as below. The application using the RealProducer SDK is responsible for interpreting an input source into streams of different data types. For example, a QuickTime source file is interpreted as a stream of audio data and video data.
