Packetization hint sample data
An atom that describes the sample data for data using the Real-Time Transport Protocol (RTP).
Overview
This section describes the sample data for the 'rtp ' format. The 'rtp ' format assumes that the server is sending data using Real-Time Transport Protocol (RTP). This format also assumes that the server “knows” about RTP headers but does not require that the server know anything about specific media headers, including media headers defined in various IETF drafts.
Each sample in the hint track will generate one or more RTP packets. Each entry in the sample data table in a hint track sample corresponds to a single RTP packet. Samples in the hint track may or may not correspond exactly to samples in the media track. Data in the hint track sample is byte aligned, but not 32-bit aligned.
The RTP timestamps of all packets in a hint sample are the same as the hint sample time. In other words, packets that do not have the same RTP timestamp cannot be placed in the same hint sample.
Choose an RTP hint track time scale that provides adequate spacing between samples (as well as adequate spacing between transmission times for packets within a sample).
The packetization hint sample data contains the data elements listed in the following table.
