[MPlayer-users] real video over rtsp

[Robert Jakab]

hello,

i'm trying to watch the real video format over rtsp.
everything goes fine at start but after cca 3 minutes
the player freezes for a while (30sec) and after that
the playing stops with the error message about bad
packet len. the complete screen dump is at the end
of the message.
is it perhaps some real media protection? i have
the information that real video (or real media, in
general) isn't fully compliant with rtsp standard,
so installing the live.com codecs also didn't help.
i'm using mplayer v1.0-pre3, which is able to stream
real video without the live codecs.

i've got one more problem yet. i want to save this
stream but couldn't make it work. the "-dumpstream"
option did not work, no even if i specified it with
"-dumpfile file_name" option. the truth is, that the
streaming (i'm still talking about the same video)
was corrupted (as i wrote before), but i didn't find
even a corrupted file on my hard drive, not even
during a stream process. does mplayer not save the
dumpfile continuously?
well, a lot of questions i have.
if anybody could help with this, i'd be very grateful.
maybe anybody meets the same problem.
thanks

here's the dump:

(i repeat, the error occurs after cca 3 minutes of
watching video and hearing the sound)
