MP4GetTrackESConfiguration - Get the elementary stream (ES)
configuration of a track
hFile Specifies the mp4 file to which the operation applies.
Specifies the track for which the ES configuration is desired.
Specifies a pointer to a pointer variable that will be given the
address of the configuration information.
Specifies a pointer to a variable to hold the size of the ES
Upon success, *ppConfig will point to a malloc’d block of memory with
the ES configuration, and *pConfigSize will indicated the number of
bytes of the ES configuration. Upon error, *ppConfig will be NULL, and
*pConfigSize will be 0.
MP4GetTrackESConfiguration returns the elementary stream (ES)
configuration of the specified track in the mp4 file. This information
is codec specific and contains the configuration necessary for the
given codec to decode the samples in the track.
Caveat: the returned block of memory has been malloc’d. The caller may
safely modify the value without effecting the library, but the caller
takes responsiblity for free’ing the memory.
