2.1.22 c-rate

This field MUST specify the rate of streaming or playback as a multiplier of the normal streaming or playback rate.

For example, a value of 1 specifies streaming or playback at the normal rate, while a value of -5 indicates rewind at a speed five times faster than real-time, and a value of 5 indicates fast-forward at a rate five times faster than real-time.

For Legacy and Streaming Logs, c-rate MUST be the streaming rate. For Rendering logs, c-rate MUST be the rendering (playback) rate.

The value of c-rate MUST reflect the rate that was in effect at the beginning of the period covered by the logging message because streaming or playback might already have ended by the time the logging message is generated.

The syntax of the c-rate field is defined as follows.

 c-rate= [ "-" ] 1*2DIGIT
