TVH with Analog PCI tuner on Debian

Alex A

Hello,

I'm using an "Avermedia AVerTV GO 007 FM" Analog PCI card (no dvb!) connected to Coax, on Debian 7.6 netinst (without X server) and I'm trying to configure it with TVH to be able to stream it.

Problem is I've never dealt with this situation before, so I'm using a multitude of software (found while googling) in order to at least capture some input from /dev/video0.

Here are my attempts:

Installed TVH from deb, but got:


tvheadend[7316]: v4l: /dev/video0: Device lacks MPEG encoder, device skipped

So I've compiled the 3.6 branch from git with the following change to src/v4l.c:

int can_mpeg = 1;

(instead of = 0).


./configure --enable-v4l --disable-linuxdvb --disable-dvbscan

After some testing and more googling, I've also changed these in src/v4l.c:

vf.frequency = (frequency * 16) / 1000;

(instead of / 1000000;)

unsigned int frequency = t->s_v4l_frequency;

(instead of int frequency = t->s_v4l_frequency;)

and recompiled.


tvheadend -C -c .hts/

Pasted to pastebin because it's too long: http://pastebin.com/THbgz3iB

I've also configured the EPG grabber (selected just 5 channels for the sake of speed):


/usr/bin/tv_grab_huro --configure
using config filename /root/.xmltv/tv_grab_huro.conf
Grab listings for which country?
0: Czech
1: Hungary
2: Romania
3: Slovakia
Select one: [0,1,2,3 (default=1)] 2
getting list of channels: ##################################################
add channel TVR 1? [yes,no,all,none (default=yes)] yes

add channel HBO? [yes,no,all,none (default=yes)]
add channel Acas▒ TV? [yes,no,all,none (default=yes)]
add channel Prima TV? [yes,no,all,none (default=yes)]

Alright, I can see my tuner in DVB Inputs / TV Adapters:

Hardware Device path: /dev/video0 Device name: Avermedia AVerTV GO 007 FM saa7134 PCI:0000:00:0b.0 Status Currently tuned to: - inactive -

Configuration / DVB Inputs / TV Adapters / Services is empty

Configuration / "Channel/EPG" / Channels is empty

I've tried manually adding some Services in 'Configuration / DVB Inputs / TV Adapters / Services' (before and after the Frequency hack in v4l.c) and then to 'Configuration / "Channel/EPG" / Channels'. I've used frequencies the scanner found but for names I just used "test" - don't know if it matters. After hitting Play I get this in the log:

I don't know what I should do next. Any help is greatly appreciated, especially after 2 days of googling X_X

As far as I know, Analog TV is not supported by TvHeadend, only digital broadcasts are... So it would require some re-wrapping the analog signal to a DVB-standard. Not impossible, someone probably did it already, but is it worth so many hacking ?

I mean, MythTV does support Analog broadcasts; perhaps it is worth investigating that option at http://www.mythtv.org/

Hi Jos,

I have, too, read that TVHgenerally doesn't support analog tv, but I've also read a few people's threads which indicated they managed doing that. Obviously none describe how they've done it (hence me posting here :( ).

It's also confusing and contradictory to TVH's own description on the main page, which states "Tvheadend is a TV streaming server for Linux supporting DVB-S, DVB-S2, DVB-C, DVB-T, ATSC, IPTV, +and Analog video (V4L)+ as input sources". I mean you either support it or don't :D

In re to MythTV, I'm not sure I want to use that. The point was to use (after this initial test) two Raspberry Pis, one for the backend and another one running OpenElec with TVH add-on, and stream on the TV set. I also liked that there is a TVH client for Android. A lot more flexibility if TVH would actually work...
