[vlc] Help on streaming /viewing DVB-T (Frence TNT) Program with VLC

[Toufik Ahmed]

Hi All,
I've a problem of viewing / or streaming a DVB-T channel (TNT) using my
DVB-T USB Stick. The tunner works fine with dvb-kernel tools using :
/usr/src/dvb-apps/util/szap/tzap -r -c ~/channels.conf "Direct 8"
and with xine player I can player the channel "Direct 8"

xine stdin://mpeg2 < /dev/dvb/adapter0/dvr0

"Direct 8" program  has this frequency 778000000

the PID for video is 160 (0x00a0) and for audio is 80 (0x0050) the
Servie id is 513.

I want to see the program using vlc locally and after on by streaming it
to another host.

my command is :

vlc --programs 160,80 -vvv --color --ttl 12 dvb://
--dvb-frequency=778000000 --dvb-transmission=8 --dvb-guard=32
--dvb-modulation=64 --dvb-code-rate-lp=1 --dvb-code-rate-hp=2
--dvb-adapter=0 --dvb-hierarchy=-1 --dvb-bandwidth=8 --dvb-budget-mode
--sout
'#duplicate{dst=std{access=udp,mux=ts,url=192.168.0.3:3001},select="program=160",dst=std{access=udp,mux=ts,url=192.168.0.3:3002},select="program=80"}'


(I've tried the value hexadecimal and decimal for program option)

at the end of this message you will find the complte dump of the result.
my question is that no things is happening (no view, no streaming):
Using ethereal snif program on the other host (192.168.0.3) I've
received only one UDP packet to the port 3001 but the packet seems to be
corrupted since in the payload there are 1472 octet at "0" bytes value.

any advises on how to play locally and by streaming the programs are
welcomed
Best regards
Toufik
