questions about invaid avc sample duration

[CCC-123]

Hi, thanks for the sharing work. But I met a problem when using it. I install the server side on a Centos server and try to connect it from a windows client in an intranet. After playing the first frame, the player stops and shows continuous outputs like:

[remuxer:h264] invalid AVC sample duration at PTS/DTS: 25200/25200|lastDTS: 32400:-7200 
[remuxer:h264] skip frame from the past at DTS=43200 with expected DTS=97200

Here is the sdp:

Can you give some suggestions about this problem ,thank you

a=rtpmap96 H26490000 it's interesting why there is no separator ":" it's strange - in sdp standartd the separator is present

[CCC-123]

I checked the log again, the separator exists in the console log. It's maybe a mistake when copying.

And I test it on Chrome, the video is lag too. The output is also like

[remuxer:h264] invalid AVC sample duration at PTS/DTS: 25200/25200|lastDTS: 32400:-7200 
[remuxer:h264] skip frame from the past at DTS=43200 with expected DTS=97200

The RTSP stream can play well in VLC player. I'm confused about where the problem is.
