I have found others problems to decode live TS streaming (UDP & RTP).

In my test setup I'm using a realtime h264 encoder that stream the
generated H264 transport stream (TS) via UDP & RTP, I'm using the
following XBMC live streaming XML:

 <?xml version=3D"1.0" ?>

 <channels>

 <channel><name>IPTV Channels</name><thumbnail>http://live-tv-
stream.googlecode.com/svn/icons/news.png</thumbnail><items>

 <item>
 <title>ENC UDP</title>
 <link>udp://224.1.1.1:1234 timeout=3D10</link>
 <thumbnail></thumbnail>
 </item>

 <item>
 <title>ENC RTP</title>
 <link>rtp://224.1.1.2:1234 timeout=3D10</link>
 <thumbnail></thumbnail>
 </item>

 </items>
 </channel>
 </channels>


In both cases (UDP & RTP) the XBMC video player is black, but the
audio is ok.

Codec informations:
  VIDEO:
    CODEC =3D AVC/H264
    bitrate =3D 5 Mbps
    Resolution =3D 1920x1080i 50Hz

  AUDIO:
    Codec =3D MPEG1 layer 2


I have tested two cases:

1) when the streaming is running, I can stop the player correctly.

2) XBMC player is running (no video, audio ok), then I stop the
streaming (UDP & RTP).
  In this case if I try to stop the player, XBMC hang, and I must
reboot the system.


Seems to be a problem when we try to stop the video player in case of
error condition. In this case the system doesn't respond anymore.
