HLS stream playback is not smooth with 1.11.2 (vlc, ffplay ok)

[lucky chou]

Ask some questions, in tsdemux, the calculation of the timestamp 
is associated with the pcr, if the file itself pcr is not continuous, 
or the interval is too large, will lead to gstreamer A/V synchronization
issure?
[In

,
Some ts file  two adjacent pcr interval of 8s, which should be regarded as a
problem well?

1. PCR:15314130000(00:09:27.190) PTS:51054570 DTS:51047100
2. PCR:15488685000(00:09:33.655) PTS:51636420 DTS:51628950  <= diff 6s
3. PCR:15713892000(00:09:41.996) PTS:52387200 DTS:52379640  <= diff 8s

Is it possible, do not use pcr to recalculate timestamp, just rely on pts /
dts in the 
file as a basis for handling synchronization?
