NAME
MP4Read - Read an existing mp4 file
SYNTAX
#include <mp4.h>
MP4FileHandle MP4Read(
const char* fileName,
u_int32_t verbosity = 0
);
ARGUMENTS
fileName
Specifies the path name of the file to be read.
verbosity
Specifies a bitmask of diagnostic details the library should
print to stdout during its functioning. See MP4SetVerbosity()
for values.
RETURN VALUES
Upon successful completion the function returns a handle to the
existing mp4 file. This is used in subsequent calls to the library to
read information from the file. Upon an error, MP4_INVALID_FILE_HANDLE
is returned.
DESCRIPTION
MP4Read is the first call that should be used when you want to just
read an existing mp4 file. It is equivalent to opening a file for
reading, but in addition the mp4 file is parsed and the control
information is loaded into memory. Note the actual track samples are
not read into memory until MP4ReadSample() is called.
