Sensoray 819 Windows SDK - Manual (Page 13)

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.
