[MPlayer-users] RTSP connection error when loading from www.3sat.de/mediathek

[Daniel Hecker]

Hi,  

I have tried to load H.264 videos from http://www.3sat.de/mediathek on a Linux netbook with Firefox and an mplayerplug-in, but streaming failed. The bug is obviously related to the underlying mplayer. 

On this website, in the settings behind the 'Einstellungen' link you can select the video type 'Mpeg4/H.264' (either Quicktime or VLC plugin, both lead to the same streaming URL). Transmission is done in RTP afterwards. But there seems to be some RTSP connection error.

Streaming from this site and with these settings is generally working in a Windows environment with Firefox and Quicktime plugin, so the server side seems ok.

I have then downloaded the streaming URL and tried to access the stream directly with mplayer from a console executing:

./mplayer -v -vo xv rtsp://ondemand.quicktime.zdf.newmedia.nacamar.net/zdf/data/quicktime/3sat/09/10/091019_ueberschallflieger_hitec_h.mp4

Console output looks like this:

********************************************

The 'rtsp_session: unsupported RTSP server' error when trying port 554 is obviously due to the fact that this RTSP server tries to send more than one stream simultaneously (error code from rtsp_rtp.c: 'A single media stream only is supported atm.') Is there anything missing in the mplayer implementation? If so, is it planned to extend this?

The following output seems as if there is a trial for an HTTP circumvention on port 80 but this is not supported by the server.

My system:

Ubuntu Linux 8.04 Hardy
Linux debian 2.6.24-25-lpia x86_32
Gnome Desktop 2.22.3
