[gst-devel] mmssrc error

Thu Oct 29 11:56:06 CET 2009

Thanks Aurelien,

I added the slash and now no segfault happen but yet I'm unable to see the stream:

gst-launch-0.10 -v mmssrc location=mms://scry.dubuque.k12.ia.us:1755/ ! decodebin ! autovideosink

Impostazione della pipeline a PAUSED ...
ERRORE: la pipeline non vuole mettersi in pausa.
Impostazione della pipeline a NULL ...
Freeing pipeline ...

the mms url is public available so If you want you can test the same url (mplayer works fine),

Nicola
