[MPlayer-users] MPlayer/MEncoder vs Real G2 stream

Wed Jan 14 17:17:29 CET 2004

I'm getting no video with this stream with MPlayer. MEncoder crashes 
with a segfault while trying to convert it:

mplayer -v -cache 512 
"rtsp://rx-wes-sea34.rbn.com/farm/*/encoder/windup/windup/g2demand/evanescence/clips/myLastBreath.rm"

Here's the output of the command above:

... and a nice core file.

Loading the core-file in gdb gives me the following for mencoder:
#0  0x08166e5b in video_read_properties ()

I'm using the versions mentioned in the outputs above, plus the latest 
win32codecs + rp9 + qt6 packages. I even redownloaded them yesterday to 
make sure they're the latest.

Thanks for your attention.
