[MPlayer-users] Cache dependent problem when playing wma audio

[Roderick Johnstone]

Hi

I have a problem with mplayer 1.0pre3 playing:

mmst://audio2.musicradio.com/Ad/onetel.wma

(This is an advert which is prepended to the streaming audio of a radio
station I listen to using mplayerplug-in 
(http://www.classicfm.com/index.cfm?nodeId=315), or at least I did until 
they changed the site to prepend this advert)

What happens is dependent on the cache size setting:

0 kB: plays choppily, terminates correctly

64kB: plays choppily, writes "everything done. Thank you for downloading
a media file containing proprietary and patentend technology." and hangs

256kB: plays well and then hangs

8192kB: doesnt play, writes "everything done. Thank you for downloading
a media file containing proprietary and patentend technology." and then
always hangs.

I first saw this in mplayer 1.0pre3 and I just confirmed that the cvs
version behaves in exactly the same way.

Can anyone else confirm this as a bug please?

My system is:
Feora core 1
kernel 2.4.22-1.2174.nptl
libc-2.3.2
gcc version 3.3.2 20031022 (Red Hat Linux 3.3.2-1)
GNU ld version 2.14.90.0.6 20030820
GNU assembler 2.14.90.0.6 20030820
AMD thunderbird 1300MHz
Sound card is:
00:0b.0 Multimedia audio controller: Ensoniq 5880 AudioPCI (rev 02)
         Subsystem: Ensoniq Creative Sound Blaster AudioPCI128


Also found the same behaviour on a redhat 7.3 system so its not a
problem with exec_shield or prelink.

Thanks

and it hangs. Sometimes it will exit if you press <cr> in the window 
running mplayer.
