access_output_udp debug: packet has been sent too late

Postby ilyasdeen » 26 Apr 2006 12:49

Hi,

I am trying to stream out a mpeg2 stream using rtsp. I am using vlc in windows platform and the command I use in the stream output dialog is:
:sout=#rtp{dst=10.80.104.69,port=554,sdp=rtsp://10.80.104.117:554/birds.ts}

however in the messages i keep getting this messages:

access_output_udp debug: mmh, packets in the past (38518)
access_output_udp debug: packet has been sent too late (37834)
access_output_udp debug: packet has been sent too late (32834)

could someone explain to me what it means? In my vlc client when I try to play it..the stream is jerky...
Thanks for the help guys!

Hi !!!

Indeed, rtsp protocol permit to synchronize stream when you receive packets, with your clock system... Shortly, Pictures embedded clock informations wich have to be synchronized with your internal client's clock.

If sync failed, you have some display trouble......

I don't really know, how you can solve this problem, maybe by changing your fps stream.......

I wish you god luck, and don't forget to post the solution if you get it.... :)
