[vlc] Re: SAP (sdr mbone) playlist freeze

[Jehan PROCACCIA]

I noticed that there's an update to vlc , from my actual 0.8.2 to -> 
0.8.4-0.lvn.3.a.4  livna-stable
I did it, but vlc still freezes as soon as I try to read SAP 
annoucements :-(

I have no more error messages in the terminal, but here's what an strace 
on vlc pid shows :
$ ps auwx | grep vlc
root      4267  1.4  2.1 112220 21664 pts/1    Sl+  09:44   0:01 vlc -v
$ strace -p 4267
Process 4267 attached - interrupt to quit
futex(0xa296328, FUTEX_WAIT, 2, NULL

then starting $strace vlc and openning play-list -> manage -> service 
discovery -> SAP annoncements ends with :

gettimeofday({1140166401, 223321}, NULL) = 0
poll([{fd=4, events=POLLIN}, {fd=6, events=POLLIN}], 2, 0) = 0
write(6, "\2\30\4\0\t\1`\3\0@\0\0\7\0`\3\2\3\4\0\3\1`\3\0@\0\0\7"..., 
1156) = 1156
ioctl(6, FIONREAD, [0])                 = 0
gettimeofday({1140166401, 226553}, NULL) = 0
futex(0x85d52a0, FUTEX_WAKE, 1)         = 1
poll([{fd=4, events=POLLIN}, {fd=6, events=POLLIN}], 2, 0) = 0
futex(0x8585bc0, FUTEX_WAIT, 2, NULL

Can it help debugging ? what is the problem ? is VLC capable of reading 
mbone SAP annoncements ?
Thanks.
