tsdemux does not do any pacing. The jitter though should be less then the 700ms latency that was declared by element in accordance to the MPEG TS specification to ensure proper timestamp calculation. What is likely the issue is that your sink element does not honour the pipeline latency (or you have explicitly set sync=FALSE) which result in a lot of jitter.
