Hi,<br><br>I am dealing with a weird issue in the either mplayer or live555 library, and I hope you can help me on this one. Perhaps it is a known bug.<br><br>The Failure:<br>
* When I invoke 1st mplayer with stream1.sdp <br>
and<br>
* wait till 1st mplayer starts decoding 1st videostream<br>
then<br>
* add 2nd mplayer with stream2.sdp<br>
=> the 1st and 2nd mplayer start decoding the second video.<br>
When I stop the 2nd mplayer, the 1st mplayer will either exit or start decoding the first video again.<br>
This effect continues while adding more videos (3rd 4th etc. They all start decoding the lastly added video.<br><br>Monitoring the network shows that both streams are still streaming, PARSE_PMT msg shows that the stream decoding has switched when the 2nd mplayer allocates + initiates the 2nd stream.<br>
Visible through the PID numbers. It is also visible in the index numbers:<br>The 1st mplayer shows (also visible below in the output snippet):<br> * streamindex 0 is the 1st stream video channel<br> * streamindex 1 is the 2nd stream video channel<br>
* streamindex 2 is the 2nd stream audio channel<br>Groupsock shows "4" for both mplayer instances, with different multicast addresses.<br><br>The behavior and setup:<br> * I am hosting 2 separate video's through VLC on multicast RTP 239.192.140.1 and 239.192.140.2 on port 5004 (same port for both!) on a windows laptop<br>
* I am streaming from a linux laptop with mplayer-vaapi client<br> * stream1 is video only<br> * stream2 is video and audio stream.<br>
* When I invoke mplayer with stream1.sdp, the 1st stream starts correctly.<br>
* When I invoke mplayer and start stream2.sdp the 2nd stream starts correctly.<br> => Ok so my video's are hosted correctly (i think)<br>
<br>The problem does not occur when I use e.g. port 5006 on the 2nd video and 5004 on the first video.<br>The problem does not occur when I use rtp://<a href="http://239.192.140.1:5004">239.192.140.1:5004</a> and rtp://<a href="http://239.192.140.2:5004">239.192.140.2:5004</a> (but that is not using LIVE555)<br>
<br>The problem occurs only when using multiple instances of mplayer with local SDP file definitions, which have video streams defined on the same port (5004).<br><br>It looks to me that a stream is overwritten or incorrectly selected from a different instance of mplayer into liveMedia library. <br>
<br>I have tried more or less all live555 library versions since 2009-06-02 up to 2012-01-13 and most mplayer versions from svn revision 32xxx to 34xxxx. They all react the same.<br><br>I also googled a bit and found some more or less related issues that occurred in the past:<br>
* <a href="http://lists.live555.com/pipermail/live-devel/2010-August/012455.html">http://lists.live555.com/pipermail/live-devel/2010-August/012455.html</a> (resulting in changelog<br> * <a href="http://web.archiveorange.com/archive/v/rmoqPnRacu5kiQlVWtKM">http://web.archiveorange.com/archive/v/rmoqPnRacu5kiQlVWtKM</a><br>
<br>My questions:<br> Can someone reproduce this behavior?<br> Am I overlooking something or is this a real bug?<br> Is decoding multiple videos on 1 port a known limitation of either live555 (or mplayer)?<br> Oh mightly mailinglist, can you help me? ;)<br>
