Summary: v1-rc7 demuxer for ASF failes

Initial Comment:
I have upgraded from Suse 8.2 to Suse 9.2 on my machine.
Had xine-lib 1.0-rc6a working with mms streams on suse 8.2.
I installed xine-lib 1.0-rc7 on suse 9.2 and get the
following error:
demuxer failed to start. (se attached BUG-REPORT.TXT
for details).
The streams are from:
http://konsol.tv2.dk/konsol2/flad/kanal/607106
an example of a stream is:
mms://mms-vod.media.tele.dk/tv2vod/vod/36627.wmv

Streams from this site used to work with suse 8.2 and
xine 1.0-rc6a.
I have essential codecs from mplayer installed in
/usr/lib/win32.

Leaving aside the legal implications, it would certainly be 
possible, because all of today's DRM system do security by 
obscurity, so they are all breakable in theory and AFAIR early 
versions of the MS DRM system have already been 
compromised. 
 
The problem here is more a legal one. xine could only handle 
any DRM system like we handle CSS now. Someone else 
would have to provide an API and a library, which we can use. 
 
Or someone has to convince the industry to work on sensible 
and open-source DRM systems...

OK!

They must have change the site while I was upgrading :-(

I can see that they want to start charging for the content,
so that
probably explains the encryption.

Does this mean that playing DRM protected material from
Linux will be
a no go?

Thanks
Stefan

The video and audio parts of this stream are encrypted 
(with DRM algorithms, i guess).
I will change the demuxer to report the encryption 
message, we have no way to play this kind of stream.

I have tried:
mmsh://mms-vod.media.tele.dk/tv2vod/vod/36627.wmv
mmst://mms-vod.media.tele.dk/tv2vod/vod/36627.wmv
and both produce the same error as the first URL.

The 4 first bytes are 0, then the rest of the header seems ok.
It needs more investigations.

This is quite strange, the stream does not start with an ASF 
header.
It perhaps a bug in the mmst protocol code.
Can you tell me if the 2 following URLs cause the same error ?
mmsh://mms-vod.media.tele.dk/tv2vod/vod/36627.wmv
mmst://mms-vod.media.tele.dk/tv2vod/vod/36627.wmv

Hi!

Just tried installing from CVS, but still the same error!

Hi!

The #nocache trick didn't make any difference:
xine 
mms://mms-vod.media.tele.dk/tv2vod/vod/36627.wmv#nocache

I'll try getting the current CVS version later and report
the result.

Could you try with a current CVS version? I believe a similar 
bug has already been fixed. 
You could also try appending "#nocache" to the MRLs like in: 
xine 
mms://mms-vod.media.tele.dk/tv2vod/vod/36627.wmv#nocache
