main demuxer warning - no access_demux

[greg221b]

Hi -
I'm trying to stream a tv signal from a DVico HDTV DVB-T Dual digital card using VLC 0.8.5test3 and video4linux - however VLC tells me main demuxer warning: no access_demux module matched "v4l"

As far as I can see video4linux installed fine;
VLC 0.8.5test3 installed fine;
and using the linuxtv-dvb-apps program tzap I get:

$ ./tzap -c ~/.tzap/channels.conf-dvbt-adelaide "ABC TV 2"
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
tuning to 226500000 Hz
video pid 0x0200, audio pid 0x028a
status 01 | signal 107f | snr 0000 | ber 00000000 | unc 00000000 |
status 1f | signal 1ebf | snr 8686 | ber 00000000 | unc 000035b7 | FE_HAS_LOCK
status 1f | signal 1f2f | snr 8585 | ber 00000000 | unc 00003cf5 | FE_HAS_LOCK
status 1f | signal 1f1f | snr 8585 | ber 00000000 | unc 00003cf9 | FE_HAS_LOCK
etc

But when I run:
$ vlc --color v4l:/dev/video:norm=pal:frequency=226500:channel=0 --sout '#transcode{vcodec=mp4v,vb=3000,ab=256,deinterlace}:std{access=mmsh,dst=:8080}' --ttl 12

I get the following output:

[00000249] access_output_http private warning: HTTP sout access cannot seek

So, being new to this, I was wondering if I've missed something basic - or have not installed something I need to install. If anyone could help me I'd be eternally grateful.

try this

vlc --color dvb:// :dvb-frequency=226500 --sout '#transcode{vcodec=mp4v,vb=3000,ab=256,deinterlace}:std{access=mmsh,dst=:8080}' --ttl 12

Thanks for the reply -
However I get a very similar error message:

$ vlc --color dvb:// :dvb-frequency=226500 --sout '#transcode{vcodec=mp4v,vb=3000,ab=256,deinterlace}:std{access=mmsh,dst=:8080}' --ttl 12

status change: ( new input: dvb:// )
status change: ( audio volume: 256 )

So, I assume I have a problem with my v4l-dvb drivers not being loaded?
Also, I I'm a bit stuck on having a dvb config file - should I have one in /etc/dvb/ (.config) ?

Thanks,
Greg

chown -R /dev/dvb/**whatever the adapter is**
chown -R /dev/**what ever the video device is**

and this should get you up and running..

However it has't affected the no access_demux error I get:

I'm looking at mplayer now - and having slightly more success.....

Hi - trying this command I now get the following (after compiling vlc with --enable-vl4 on the ./configure ):

$ vlc -vvv v4l://

Gives:

[00000252] main input debug: creating demux: access='v4l' demux='' path=''

Does this look familiar to anyone?
