[linux-dvb] Technotrend S2-3200 Scanning

[linux-dvb] Technotrend S2-3200 Scanning

[Jelle De Loecker]

Hi again,

It's been a busy day. So I temporarily removed LinuxMCE to install the 
newer Mythbuntu 8.04 - the drivers finally recognize the S2-3200!

But now I'm stuck again, and it seems to me this is a problem which has 
been faced, and fixed, before - I just can't fix it now because 
apparently so much has changed that all the patches don't work on the 
new source files anymore: any hacked "scan" or "szap" program won't compile.

(Keep in mind I'm using a switch between my S2-3200 card and my 4 LNBs - 
will this cause any problems?)

This is the problem you've no doubt seen before.

$ sudo scan /usr/share/doc/dvb-utils/examples/scan/dvb-s/Astra-19.2E 
 >channels.conf

Re: [linux-dvb] Technotrend S2-3200 Scanning

[Jelle De Loecker]

Hi Igor,

I've tried using a version from the repository, dvb-utils 1.1.1-3

I also tried to compile the originals from the source tree, unpatched, 
http://linuxtv.org/hg/dvb-apps

I tried to patch "scan" with this scan source: 
http://jusst.de/manu/scan.tar.bz2

And I tried to patch szap with this file:  
http://abraham.manu.googlepages.com/szap.c

But those patched versions won't compile, except for ONE time:

I finally got to compile the patched "scan" (but trying to recompile 
afterwards failed again, very strange) but it *still* didn't scan:

$ sudo scan -t 1 -s 1 dvb-s/Astra-19.2E > ~/channels.conf
scanning dvb-s/Astra-19.2E
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
initial transponder 12551500 V 22000000 22000000
ioctl DVBFE_GET_INFO failed: Operation not supported
ERROR: initial tuning failed
dumping lists (0 services)
Done.

yes, you have to use szap2 in the TEST directory  with the latest multiproto
http://linuxtv.org/hg/dvb-apps/file/31a6dd437b9a/test/szap2.c

imho, this versions are not actually. 
It seems to me there's not any working scan's version for currently multiproto.

I postet a patch a few weeks ago (here again).
These szap and scan patches prepare the apps for actual multiproto (well 
for multiproto a few weeks ago, if the api hasn't changed again, these 
should work).

you have to patch the szap and scan from this sources:

I fear things have changed too much for the patches to work. (Or I'm 
messing up a simple command like patch)

hi, i installed multiproto a couple of weeks ago and tried a lot of 
patches for szap / scan or already patched szap2 sources and none would 
work..

But i did find out that szap2 available in v4l dvb-apps tree, in the 
test directory, works fine with current multiproto.

I've tested it with my tt s2-3200 and can tune to dvb-s2 transponders 
with no problem, although i noticed it misses some options from some 
other szap2 i first tested..

Yes, thank you, I finally got szap2 to actually catch a signal and get a 
lock on it.

But since only szap2 works - what do I do now?
How can I watch the stream? (I tried to run "mplayer -fs 
/dev/dvb/adapter0/vdr0 but that never worked)
Or how can I get it to work in MythTV? Do I have to wait for the new 
utilities, which would seem rather strange since they're not used by 
mythtv, right?

Thank you,

This means you did the channel scan and saved channel.conf file in
/home/username/.szap

szap -rp "BBC World"   (you can replace BBC World with any channel in
your channel.conf) and make sure you get FE_HAS_LOCK before you start
mplayer.

mplayer /dev/dvb/adapter0/dvr0

mythtv: there is multiproto patch for mythtv-svn. I tried it but it
always failed med after 1 hour of compiling it's nothing to do with
the patch anyway here is the link to the patch.

http://pansy.at/gernot/mythtv-multiproto-hack.diff.gz

easiest way is to use vdr, I'm using vdr-1.6.0-1 stable version.
if you want to use the stable version you have to search for this
patch [ANNOUNCE] DVB-S2 + H.264 support for VDR-1.5.18 in vdr mailing
list and patch the vdr source.

There is vdr developer version 1.7.0 which support multiproto but you
still going to need H.264 support patch which can be found at vdr
mailing list.

I've managed to get a lock - well no problem there actually, but when I 
try to use mplayer I'm lost:

$ mplayer /dev/dvb/adapter0/dvr0 (or mplayer -fs /dev/dvb/adapter0/dvr0)

Playing /dev/dvb/adapter0/dvr0.

So it says it's playing (the "could not connect to socket" is purely a 
lirc problem) but where's the video?
I also tried gmplayer, but that just locks up.

did you run szap with -rp ? make sure the channel you tuned to is not encrypted.

here is another ugly way of doing it.
u need dvbstream and vlc

szap -rp "BBC World"
dvbstream -o | vlc -
or with with mplayer: dvbstream -o | mplayer -

There is two version of dvbstream out there, patched and unpatched.
it should work with both of them, but with multiproto patched version
you dont need to run szap it can tune and lock to channels by it self.

link to the patched version:

Very strange,

when I run dvbstream -o, without piping it into anything, I get a lot of 
binary feedback in the console, but I just can't open it in any program. 
(I tuned it using szap2, with the -rp option. I only tried unencrypted 
channels, so no problem there) dvbstream always says "streaming 0 
streams" which is probably not so good.

    $ dvbstream -o | vlc -
    dvbstream will stop after -1 seconds (71582788 minutes)
    Output to stdout
    Streaming 0 streams
    VLC media player 0.8.6e Janus

    libdvdread: Can't stat -
    No such file or directory
    libdvdnav: vm: faild to open/read the DVD
    libdvbpsi error (PSI decoder): TS discontinuity (received 3,
    expected 0) for PID 0


I even tried to output it to a file, but the file stays blank

    $ dvbstream -o:test.mpg
    Open file test.mpg

    MAP 0, file test.mpg: From -1 secs, To -1 secs, 0 PIDs -
    dvbstream will stop after -1 seconds (71582788 minutes)
    Streaming 0 streams


And when I give mplayer a go I get this:

    $ dvbstream -o | mplayer -
    dvbstream will stop after -1 seconds (71582788 minutes)
    Output to stdout
    Streaming 0 streams

Thats all that i know, i started with dvb about 2 months ago and your
card is supported unlike my TT Connect S2-3650 CI, but some how i
managed it to work.

output to a file this two command should work.
as always run szip2 first.

cat /dev/dvb/adapter0/dvr0 > test.mpg
or
dvbstream -o > test2.mpg

dvbstream v0.5 - (C) Dave Chapman 2001-2004
Released under the GPL.
Latest version available from http://www.linuxstb.org/
Output to stdout
Streaming 0 streams

works 100% here Streaming 0 streams i thinks because we are using
output to file instead of streaming over network.

to stream i use:
dvbstream 8192 -i 192.168.0.103 -r 1234

dvbstream v0.5 - (C) Dave Chapman 2001-2004
Released under the GPL.
Latest version available from http://www.linuxstb.org/
Setting filter for PID 8192
Using 192.168.0.103:1234:2
version=2
Streaming 1 stream


8192 means stream the whole TS stream, -i your ip address and -r is port number.

then run vlc (mine is in Swedish so I'm guessing here) File-> Open
Networkstream or press Ctrl+N. The first option UDP/RTP enter port
number press OK.

or from command line: vlc udp://@:1234

Don't worry if nothing shows as i said before you are streaming the
whole TS stream. you can select the channels you wanna watch.
To select channels click on (in swedish Navigering) translates
Navigation -> Program-> you should see list of channels.

This "just worked" for me using mplayer with a digital video broadcast
from my HVR-1600 with the cx18 driver (I'm in ATSC country):

$ scandvb -A 1 -v -a 0  /usr/share/dvb-apps/atsc/us-ATSC-center-frequencies-8VSB \
	> channels.conf
$ cp channels.conf ~/.mplayer/channels.conf
$ mplayer dvb://WRC-1 -vf scale=960:540

The "scandvb" command name might be a rename by Fedora/Redhat of the
standard command name.

I had to use the '-vf scale=960:540' to display the 1080i content on my
1024 line display.  Also note that mplayer sometimes wrongly decodes a52
audio (at least from ATSC streams) so it'll gripe every so often.

For reference:

$ mplayer --help | head -1
MPlayer 1.0rc2-4.1.2 (C) 2000-2007 MPlayer Team

$ uname -rvi
2.6.23.15-80.fc7 #1 SMP Sun Feb 10 16:52:18 EST 2008 x86_64

Apparently /dev/dvb/adapter0/dvr0 is a very sensitive "file" - when I 
directly open it using mplayer, or even cat, it won't output to anything 
else afterwards.

I'm using Faruk's solution to stream it like this:

dvbstream 8192 -i 192.168.1.2 -r 1234

and then opening that stream with VLC - which works rather well (even if I have to always manually change the frequency using szap)


By the way, I scribbled down my notes in a small tutorial on how to get 
the "old drivers" working again (using an older revision made the scan 
tool work again!) If any other beginner needs any help it can be found here:
