NAME
MP4SetRtpTimestampStart - Set the RTP start time of a hint track
SYNTAX
#include <mp4.h>
bool MP4SetRtpTimestampStart(
MP4FileHandle hFile,
MP4TrackId hintTrackId,
MP4Timestamp startTime
);
ARGUMENTS
hFile Specifies the mp4 file to which the operation applies.
trackId
Specifies the hint track to which the operation applies.
startTime
Specifies the desired RTP start timestamp for the hint track.
RETURN VALUES
Upon success, true (1). Upon an error, false (0).
DESCRIPTION
MP4SetRtpTimestampStart sets the RTP timestamp start of the specified
hint track. Typically this is a random value that is chosen when the
first RTP packet is constructed by the MP4 library. However the value
can be set explicitly for the hint track and stored. Typically this is
used if it is desired that timestamps start at zero.
See IETF RFC 1889 for details regarding RTP timestamps and RTCP.
