From: nextime on 31 May 2009 06:00 After trying also to update, the issue remain the same. But i've found something new. After many try, i found that if i try to open the stream using mplayer ( with subprocess.Popen ), if i set the -nocache option in the mplayer command line, i don't get any sound and i see in stdout "stream not seekable", if i put a -cache 32, all work great. The same using directly WMP, if i let the player doing some caching, it work, if i set cache to 0 it won't work. So, maybe can be just a caching issue, on gstreamer it work, but on quicktime and wmp if i don't let the player doing some minimal caching, the stream won't work, and wx.media.mediactrl seem to launch the player without any caching. Is there any way to set a minimal cache on both wmp and quicktime? On Sat, May 30, 2009 at 05:02:34AM -0700, Jacob wrote: > Have you tried upgrading your version of Python to 2.6?

Well, making some extra tests, there are some news about my issue. On Sat, May 30, 2009 at 02:57:33AM +0200, nextime wrote: --SNIP-- > > I'm trying to open an ogg audio stream from an icecast server.

A little hack solve the problem. Just using mp3 streaming ( bad thing... but it is a codec issue, not a wxpython one ) and forcing WMP10 backend it work great. > - On OSX, it work "ramdomly" Here the problem remain. But it isn't really random, the problem is when i try to open an icecast stream. Assuming to eliminate every codec issue, i'm now trying to open the mp3 stream. Using QuickTime directly, if i try to open the url of my stream, http://skylive3.astronomix.org:8000/skylive.mp3, it won't work. But if i do the trick to change http:// with icy://, it work good. Trying to use http://skylive3.astronomix.org:8000/skylive.mp3.m3u won't work. Using wx.media.MediaCtrl, it won't work at all, my stream will never be opened, and the MEDIA_LOADED event will be never catched, even if i try to open icy://... Anyone have an idea on what i can i try? -- SNIP -- > My code is here: > http://www.astronomix.org/trac/browser/trunk/skylive-ng/src/gui/stream.py -- Franco (nextime) Lanza Busto Arsizio - Italy SIP://casa(a)casa.nexlab.it NO TCPA: http://www.no1984.org you can download my public key at: http://danex.nexlab.it/nextime.asc || Key Servers Key ID = D6132D50 Key fingerprint = 66ED 5211 9D59 DA53 1DF7 4189 DFED F580 D613 2D50 ----------------------------------- echo 16i[q]sa[ln0=aln100%Pln100/snlbx]sbA0D212153574F444E49572045535520454D20454B414D204F54204847554F4E452059415020544F4E4E4143205345544147204C4C4942snlbxq | dc ----------------------------------- |
