[ Solved ] Fritz 6490 v7.10 not working

Jens Friedrich

Hi,

i have a Fritzbox 6490 with DVB-C which works well with VLC using the exported m3u File of the box file which looks like this:


#EXTINF:0,Das Erste
#EXTVLCOPT:network-caching=1000
rtsp://192.168.178.1:554/?avm=1&freq=346&bw=8&msys=dvbc&mtype=64qam&sr=6900&specinv=0&pids=0,16,17,18,20,100,101,102,103,104,106,84,105,1176,2070,2171

TVH ist installed on debian these days in stable version 4.2.8-31~g0a60f73ee.

It is located with 4 IP addresses (192.168.178.111-114) in same subnet as the 6490 (192.168.178.1).

/etc/default/tvheadend

TVH_ARGS="--trace --debug --satip_xml http://192.168.178.1:49000/satipdesc.xml"

TVH and 6490 are communicating, but TVH allways sends "408 Error - Time out" back to 6490, after 6490 has responded OK the requested PLAY command from TVH.

Problem seems to be, that TVH is not sending the correct answer to 6490 that RTP stream starts -> see VLC communication below.

TCPDUMP looks like this:

    ISO/IEC 13818-1 PID=0x988 CC=13
    ...

The difference is e.g. in the PLAY command:


TVH:  Request: PLAY rtsp://192.168.178.1/stream=1131?&freq=346&sr=6900&msys=dvbc&mtype=256qam&specinv=1&pids=0,21 RTSP/1.0
VLC:  Request: PLAY rtsp://192.168.178.1:554/stream=1 RTSP/1.0

so i assume that this short PLAY command is enough, because it was defined by streamID before by SETUP already.

No Support / Interest for AVM DVB-C anymore?

Joe User

Have you tried tvheadend version 4.3> There have been some changes/fixes to the satip code.

Jens Friedrich

Yes, there is no difference

besides that the startscripts are buggy - they don't read the --satip_xml param from etc/default/tvheadend

Jens Friedrich

We see in VLC Communication, that after the
0) Reply 200 OK

with the communication channel definition (client_port=x Server_port=y)

VLC opens the respective RTP UDP channel

1) 62535 -> 5001

before the command is sent to 6490 SatIP Server

2) PLAY

and the Stream starts afterwards

3) RTP + MPegTS

The TVHeadend Server doesn't open this Channel, so this is the error i suppose:

Hi, may just worth a try, when i still had the 6490 (im on 6591 now due upgrade but sadly no Fritz DVB-C currently) and the update came for 7.03 or so, i had to remove the --satip_xml http://192.168.178.1:49000/satipdesc.xml line due AVM added their way to announce SATIP now.

may just worth a try to remove the tuner and start tvheadend without --satip_xml http://192.168.178.1:49000/satipdesc.xml,

so it should find the tuner as SATIP Tuner in the network and then just readd it, worked here at least.

Joe User

In your first post you have:

vlc = "freq=346&bw=8&msys=dvbc&mtype=64qam&sr=6900&specinv=0"

tvh = "freq=346&sr=6900&msys=dvbc&mtype=256qam&specinv=1"

which is correct???

Then second post you have:

"freq=634&bw=8&msys=dvbc&mtype=256qam&sr=6900&specinv=0"

You post results tested with the same channel in order to compare...

I tried this. Thus i added the 4 additional IPs of TVH in the same subnet where the 6490 is located.

But without --satip_xml TVH doesn't find the DVB-C SatIP server of the 6490.

Anything specific to configure TVH that it gets the 6490 SATIP info's ?

The channel is not relevant ... no channel works with tvh, all with vlc.

it wasnt here at least ... and the extra ip´s where also not needed anymore since fritz 7.x ... the 1 stream/ip limit should be also gone ... sorry, as i said i have no more 6490 here, waiting for 6591 to support dvb-c,

all i can say is i removed every extra i added for fritz satip and it worked "out of the box".

im running tvheadend in a docker container and it has to be in host mode to use satip ...

Got it working:

--> network interface didn't got packets from UPnP Port UDP 1900 (firewall).

Yeah -> now i want to feed my PLEX with DVB-C

xteve is a good start point, enjoy
