VLC stop restreaming after 3 minutes

[hcan]

I am using vlc to restream an rtp stream as another rtp stream. I need this becouse my camera does encodes with H264 baseline level4 and iphone 3G can only stream baseline level 3.

It starts perfectly... everything fine for the first 3 minutes but atfet it, vlc stops streaming. I use a code like below.

vlc -vvv rtsp://user:pwd@x.y.z.t:554/media.amp --sout "#transcode{venc=x264{keyint=60,profile=baseline,level=3.0,nocabac,qpmax=36,qpmin=10,me=hex,merange=24,subme=9,qcomp=0.6},vcodec=x264,vb=500,scale=1,acodec=mp4a,ab=96,channels=2,samplerate=48000}:rtsp{dst=127.0.0.1,port-video=10000,port-audio=10002,sdp= file://%WMSCONFIG_HOME%/content/was.sdp}" --sout-keep --loop

i added " --sout-keep --loop" to keep user connected even the stream stopes. And after 3 minutes restart streaming. This solves the problem but its not good. User buffer for 10 s every 3 minutes for this issue.

Do you have any idea? What could be cousing it?

Thanks for your help.

Hi my friend.

Yes, this also helps with me, but not for every 3 minutes, in my case is 7 minutes instead!

Seems that VLC keeps resetting the connection ! but i dont know why yet.

The rtsp layer on vlc is from livemedia live555 package, i have aleady sent a message to them, but no answers yet.

There is a guy that used freebsd in past and was blaming the live555 people to be guilty for this error, but them was not guilty ! it was a vlc fault : http://lists.live555.com/pipermail/live ... 08977.html

This is what happens : (-vvv mode on !!!!)

The strange thing is that on windows this DOESNT HAPPEN. Only on linux !

As i can see vlc is the one that closes the connection, not the rtsp server !

PS : please, can anybody on list help us ?

[victor_diago]

Hi again !

I have found this topic : viewtopic.php?f=2&t=58959&p=231851&hili ... ps#p196956

Look here ! :

We just confirmed that this is a problem with VLC and the use of GET_PARAMETER as an RTSP stream keep-alive. The latest versions don't "ping" the encoder/server with this keep-alive handshake. This was broken with 0.8.6e, and the problem documented with trac Ticket #1881. Unfortunately, it was recorded as "fixed" when it apparently isn't.

i know we can play more than 20 seconds, but makes sense !

Anyone here can say if its fixed ?

Thanks

[victor_diago]

My friends,


I think i have issued the problem !

Im running linux inside vmware, and i have tried on a native linux install ! everything worked like a charm.

Im sorry but the problem Seems to be on vmware and not on linux or VLC !

Thanks again !

[cycchow]

I have the same problem under opensuse 11.0 to 11.3, can I know how to fix it?

[Edwin]

I have a problem when I streaming two video in a mosaic. I put loop function for each video repeat but when video repeat two time then close!!

[victor_diago]

Hello All

I have really resolved the problem of stop re-streaming.

cycchow -> My problem was because the rtsp protocol need to use UDP ports to send keepalive acks from client to server, and in my case, udp was blocked !. Then the server after waiting for the never coming ack answers, resets the connection.

To solve this, you can disable your AND your camera firewalls. try on local lan, this is the best way to issue the problem, because the local lan usually dont have a firewall !

Edwin -> please, can you explain how do you do a mosaic ????

Thanks All

[Edwin]

ok! I want to streaming video endlessly in my mosaic but when repeat two times after vlc close.

[victor_diago]

Right Edwin, i understand, but i have asked HOW DO YOU CREATED A MOSAIC !

Please, i will need to do it soon, so please, explain me how to do that then i will help you to keep it running ok ?

Thanks in Advance !

Best Regards !

[Edwin]

ok! This is my code: please check !! Thanks

I need answer about last code!!! Thanks!!

[victor_diago]

Right !

You are using vlc in a way that i dont know !~i only know command line, but i will study your code to issue the problem ok ?

thank you

[cycchow]

I have check the udp port is opened, however this problem only found in linux, but not in windows.
