Hi,
I have some problems getting my DVB channel syntax right on the VLC gui for direct viewing.

DVB card Nexus-S
Suse 9.3
VLC 0.8.2 rebuild with --dvb-enable

I am trying to insert the SIDs (via --programs=) into the DVB:/ line but the results are bizarres, some time I get Euronews sound and CCTV9 image, sometimes just the sound, sometimes nothing (obviously depending on the syntax I use).

In the DVB viewing Docs, there is no mention of the correct syntax to use for DVB, I tried some of the DVB stream one (like adding --programs 1709,920 or --programs=1709,920 or programs 1709,920 ...) but no luck

If I szap and then use Video capture card (/dev/video0), I have image and sound.

So anybody knows what should be in that line ?

Thanks.

Could you give the output of szap ( or an eztract ).

I don't know dvb well but a common mistake is to miskake SID and program id. Your program seems to be quite high number.

In your szap output do you have stuff like 1907:920:7 ? Then try 7 as program instead of 1907

hth

sat 13, frequency = 11034 MHz V, symbolrate 27500000, vpid = 0x0398, apid = 0x03a2
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
status 01 | signal a704 | snr 9183 | ber 0000c20b | unc 00000000 |
status 1f | signal af0c | snr b541 | ber 00004e00 | unc 00000000 | FE_HAS_LOCK
status 1f | signal af08 | snr b586 | ber 00000000 | unc 00000000 | FE_HAS_LOCK


channel.conf entry like

Euronews:11034:v:13:27500:920:930:1709

From lyngsat in Decimal SID = 1709 VPID = 920 and audio 930

I can't figure out from the doc how to pass this onto the DVB capture

if I only use the followinf in the DVB capture dialog box
dvb:// :dvb-adapter=0 :dvb-frequency=11954000 :dvb-srate=27500000

I get Euronews Audio channel in French

using

vb:// :dvb-adapter=0 :dvb-frequency=11034000 :dvb-srate=27500000 --programs=920

I have Demain (SPID 1704VPID 420 Audio 430).

So I have some postive response but not what I expected.

I suppose that if I add more VPID in the programms I should have more video track to choose from in the video drop menu, but if I do so I get audio tracks (using vpid).

very strange indeed.

Just realized what you meant by program, it's unrelated to the SID/VPID ...

The question is then how does the program number relates to the MPEG stream held in the channel defined by the frequency.

I'm getting there,

Not specifiying anything else but the frequency I get a list of VPID in the navigation menu which correpond to the vpid in the mpeg downstream !!!!!!!!

Funny that now I can have all channel (but Euronews) and Euronews sound on every channel I select pus the sound of the channel.

Anyways, enough for today, I made some giant steps already, thanks a bunch.

JP.

What is the best way to remote control the dvb-card of my linux streamingserver? Can use the http-server for channel switching and tuning, or can I use the telnet interface?

Best regards
Bonbini
