MP4 Multiplexing Functions

The 819 SDK was designed to be as flexible as possible for end users. Some users may want to save

the encoded data to the .MP4 (ISO/IEC 14496-14) file format. A separate optional DLL, sraymp4.dll,

is provided for this. The functions for writing .mp4 files are described below. Sraymp4.dll is licensed

for use only with Sensoray products.
