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: https://drive.google.com/open?id=0B22GsWueReZTVVF5Um9leFZXUXM Thank you, Ran
