RTSP RTCP SR problem

[sjbyun]

Hello,
I use VLC-2.2.2

My RTSP server send first RTCP SR, before sending H264 RTP pakcet. ( about 5 sec before - for test )
Then, VLC wait SPS, despite My RTSP server sent SPS first 5 sec after RTCP SR.
Packet arrival was confirmed by wireshark. ( RTCP SR and SPS )

It seems that VLC discard first RTP packet for resync. ( I guess )

What is the reason?
How to solve it?

no RTCP case

Code: Select all

That would be a bug in live555 plugin or live555 library.
