[FFmpeg-user] PCR sync is required for audio-video sync ?

[Ran Shalit]

Hello,

I would like to ask , if someone from experience can say if PCR sync
between encoder and decoder is required for ts streaming, when it
required to acheive audio-video sync ?

I ask the question becuase I've noticed that some ts samples I am
using are played perfectly with VLC, even though there is no usage of
PCR sync (I see in wireshark that PCR flag is always 0).


for example:
