resume from standby: it takes aprox 1 minute before CWC is connected

Marcel Peeters

Running XBMC frontend and tvheadend on my HTPC. seems to be working pretty good.

CWC running newcs on my dreambox500 with ziggo card.

however 2 problems:
1) Need help with thisdelay of 1 minute before CWC connection is re-established after resume from standby.

Waiting for 1 minute after resume is a very long time! Meanwhile XBMC repeately pops message "TVHEADEND: no input detected" I gues this happens:

tvheadend tries to connect to cwc immediately. But network connections not up and running yet. After 1 minute retry... success

log:

2)sometimes screen freezes, zapp to other channel:
- log shows repeately: "capmt: Removing CAPMT Server from service" followed by "capmt: Starting capmt server for service "Nat Geo Wild" on tuner 0"
- XBMC repeately pops message "TVHEADEND: no input detected"

- have to restart tvheadend to get it running again

any help on either of the problems is welcome...

do you only have CWC configured? or also capmt?

if you only connect to the newcs server on your dreambox then yo do not need to configure capmt.

Marcel Peeters

I know... had another setup before (both dreambox and htpc running CCcam, takes ages to switch between channels)

I disabled the capmt settings (didnt remove them).

Tried another thing today, looking at tvheadend webinterface on HTPC, manually restart tvheadend via terminal, monitoring the debug log in webinterface: connection to CWC is made immediately....

this kinda proves my point: after resume initially tvheadend tries to connect but fails (not visible when: HTPC resumes and monitoring tvheadend webinterface via laptop) after a minute connection is made again and now succeeds.

hope this info helps...

Hi,

found a workaround for the first problem:
already had a script stoppping / starting during standby and resume (in /etc/pm/sleep.d)

instead of starting tvheadend directly in this script (service tvheadend start) i created a script for this command and start it in background

script:

!#bash
sleep 8

service tvheadend start

result after resume: XBMC screen appears-> network connection OK pops up-> popup: XBMC, "reconnected to tvheadend".

No I can Immediately zap to a channel that needs CWC

the other problem no success (yet) (very annoying...)

brad Schmidt

Marcel,

I am having the resume issue as well. How can I create this script and run it as you have done? Where do I put the scipt? I know how to create. Your help would be greatly appreciated. I have a very frustrated wife.

brad Schmidt

Marcel,

Can you post your entire script that you are using?

Marcel Peeters

Hi,

@ work right now... wont be able to reply with details until monday.

I created a startup script for XBMC
while true do
{
startxbmc
sleep 9 seconds

}

after resume from standby add to resume script to restart tvheadend somewhere in /var/etc/pm/sleep.d

last line killall -9 xbmc.bin

effect: after resume xbmc shows up but it is killed after a few seconds, then the starup script makes sure that xbmc

is restarted but first it waits for 9 seconds, during this time network is up and running and also EPG info is refreshed!!

the above story is not entirely correct (also tvheadend needs to restart after network is reconnected)

brad Schmidt

Marcel,

Its great to hear from you. I will wait until monday. Thank you,

Brad

Marcel Peeters

first the startup script:

copy and paste text below into file and make it executable. select it in System->Preferences->Startup Applications

----------

#!/bin/sh
sleep 8
while [ 1 ];
do
xbmc
sleep 1

done

-----------

effect: starts XBMC upon startup and when xbmc is killed or exitted it is also restarted.

to stop it you need to kill the script...

Marcel Peeters

hi,

second part is a script located in /var/etc/pm/sleep.d
i named it 99xbmchtc
make it executable and it will be executed during a suspend and after a resume from suspend
'99' at the beginning of the filename makes sure it is executed_before_ all other scripts in this directory during suspend

and_after_ all other scripts during resume

-------------

#!/bin/sh

case "$1" in
suspend|hibernate)
/etc/init.d/tvheadend stop
/etc/init.d/lirc stop
rmmod mantis
;;
resume|thaw)
modprobe mantis
/etc/init.d/lirc start
sleep 1
/home/minime/starttvheadend.sh &
;;

esac

--------------------

effect:
during suspend/hybernate following is executed:
- tvheadend is stopped
- lirc is stopped

- mantis driver is removed (this is the driver for my DVB-card, you probably have another card)

during wakeup/thaw following is executed:
- mantis driver is loaded
- lirc is started

- script: starttvheadend.sh is executed (more in part 3 about this script)

Marcel Peeters

hi,

part 3:

create a script and make it executable (i named it starttvheadend.sh)

This script is started in background during resume

-------------------------------

#!/bin/sh
sleep 5
echo "yourpassword" | sudo -S killall -9 xbmc.bin

service tvheadend start

--------------------------------

effect:
- sleep awhile to make sure everything is back up and running (remember this script is executed after resume)
- kill xbmc (fill in correct password)

- start tvheadend

combined with the other scripts the effect after resume is:
- drivers loaded, lirc started
- sleep awhile so everything is up and running again : NETWORK!!
- xbmc is killed but automatically restarted after a while because of the startup script: effect update of EPG info!
I had the problem that after long time standby EPG was not correct anymore, restart of xbmc forces an EPG info update

- tvheadend starts AFTER network is up and running hence connection to CWC succeeds immediately. (and not 1 minute later when retrying to connect to CWC)

It is not the most elegant way to fix these problems but it does the trick!

Marcel,

These are great instructions! Thank you for putting it together.

In Step #1, "copy and paste text below into file and make it executable. select it in System->Preferences->Startup Applications", do I put this script in /etc/rc.local? I am doing all of this through the terminal using SSH.

brad Schmidt

Sorry, check that, does it go in /etc/init.d?

brad Schmidt

One more, how do I determine which driver TVheadend is using?

brad Schmidt

And... Step #3 - Does it matter where I put this script?

brad Schmidt

Okay, after reading through your instructions I see you put them in your home directory and it seems that I have everything setup. When I resume XBMC the TV stations are working great. So it seems that the scripts are working, except for the EPG. There is no info in the EPG. To get the EPG back I have to into XBMC settings for Live TV and reset the EPG, then it will fill everything in. Any ideas?

Marcel Peeters

Hi,

I think i checked "do not store epg info in database" (in xbmc, live tv settings)

That will for sure force an update of epginfo since the data is not stored in XBMC but retrieved during startup and updated every X minutes (setting)

Did you figure out which driver was used?

command: "lsmod" will list all loaded modules, also "dmesg" will show you more details on the drivers that are loaded...

Greetz

Marcel

brad Schmidt

I did find the correct driver. Just had to use my brain and I found it. Thanks again for the help. Its really great that the XBMC community is willing to help people. Great help. Thanks

brad Schmidt

Marcel,

I tried checking "do not store epg info in database" (in xbmc, live tv settings) and I am still getting a "disapperaring" EPG. Sometimes when resuming it is there and the next time it won't be. Also, when I do a complete shutdown/restart it also disappears and the only way to fix that, so far, is to "reset EPG" in the XBMC Live Tv settings. It will then re populate it. I wish I could narrow down when exactly the EPG doesn't resume properly, it has been random to me so far. Any ideas?

Marcel Peeters

Hi,

Do you have the same situation as i do? (I mean xbmc is killed and restarted after resume from standby hence epg info is updated)
if so you could try to give tvheadend a little more time to retrieve the EPG info. Dunno how it works but i think tvheadend also needs to
somehow collect the data from your dvb card (for which the driver just has been loaded).
Lets say your card is a bit slower in collecting epginfo and hence tvheadend is also slower collecting all the data.

The epg update for XBMC happens upon restart. If at that point in time the epginfo simply is not complete yet you might experience missing EPG info.

thus increase the "sleep 1" in the runxbmc.sh to for instance "sleep 10". This will give tvheadend lots of time to update.

If this works, decrease to an acceptable sleep period were it still works.

(note: I assume that your are not using xmltv to collect epg ingo but epginfo is retrieved via your dvb card)

Also you could try is NOT to unload and load the driver for your dvb card (rmmod/modprobe) That did not work for me but it might do the trick for you.
