[Help] Tvheadend, scan result: FAIL

Saadulla A

Hello,

I'm using NooElec NESDR Mini 2 SDR & DVB-T USB Stick (RTL2832 + R820T2) to get local network Tv channels.

the followings are steps and options that I've done.

Where I did the mistakes?

Invalid argument = wrong/not enough frequency information, what are you entering for a mux?

Hi,
this is what I entered:

Hello dear friends,

with w_scan I can get TV channels, and I've created a vlc playlist with this command:


w_scan -c iq -L > playlist.xspf

<track>
<title>0001. Se Line HD</title>
<location>dvb-t://frequency=474000000:inversion=2:bandwidth=8:code-rate-hp=9:code-rate-lp=9:modulation=0:transmission=0:guard=0:hierarchy=0</location>
<extension application="http://www.videolan.org/vlc/playlist/0"> <vlc:id>2</vlc:id>
<vlc:option>program=257</vlc:option>
</extension>

</track>

but when I was trying to get channels with tvheadend I can not get any results, it shows me this error:

You need to supply more details for the mux, avoid AUTO.

I've only these information about each channel:


<track>
<title>0001. Se Line HD</title>
<location>dvb-t://frequency=474000000:inversion=2:bandwidth=8:code-rate-hp=9:code-rate-lp=9:modulation=0:transmission=0:guard=0:hierarchy=0</location>
<extension application="http://www.videolan.org/vlc/playlist/0">
<vlc:id>2</vlc:id>
<vlc:option>program=257</vlc:option>
</extension>
</track>

I placed informations as follows:
Frequncy:474000000 Bandwidth:8 Constellation: ?
Transmission mode: ?
Guard interval: ?
Hierarchy: ?
FEC high: ?
FEC low: ?

PLP ID: ?

What about the other AUTO fields?

Try setting the bandwidth (usually 8mhz), Transmission mode (8K), and Constellation (try QAM/64). Not all muxes use the same frequency details so try getting just the one working first.. If you get "no data, scan failed" instead of "invalid argument" once you've set these you're on the right track, you'll just need to figure out what the correct values are (Google "<Your country> DVB-T frequencies").
