Finally, I found these error logs about RTP/AVSyncMethod
WARN server comment 2023-12-17 19:38:04 - - - - - 426.976 - - - - - - - - RTPDePacketizerBase.Waiting for RTCP packet. See docs for (Application.xml: RTP/AVSyncMethod and RTP/MaxRTCPWaitTime).
WARN server comment 2023-12-17 19:38:08 - - - - - 430.776 - - - - - - - - RTCPHandler.isTimeSyncReady: Hit MaxRTCPWaitTime synchronizing on system clock.
and following exlaination in this thread, i changed the RTP/AVSyncMethod property to the systemclock and the AV streams seem to be synced correctly and I was able to view the stream.
Thank you, community.
