28 Upon successful completion the function returns a handle to the exist‐
29 ing mp4 file. This is used in subsequent calls to the library to read
30 information from the file. Upon an error, MP4_INVALID_FILE_HANDLE is
31 returned.

34 MP4Read is the first call that should be used when you want to just
35 read an existing mp4 file. It is equivalent to opening a file for read‐
36 ing, but in addition the mp4 file is parsed and the control information
37 is loaded into memory. Note the actual track samples are not read into
38 memory until MP4ReadSample() is called.
