EPG update validation before 'empty epg'

[martint123]

After the UK source for EPG - Radio Times and XMLTV has gone titsup for the moment....

Wishlist - some verification of EPG data files for the gbpvr update - especially when the 'empty epg' option is set. Maybe don't empty if the data file is less than xxx kb.

I know it's a pain - it's happened to me too but I think it's our job to make sure that the xml file is correct before we ask gbpvr to empty/update epg.

I'm trying to work out how to do it in my downloadepg.bat file. Definitely do'able I'm just not very good at windows scripting.

[martint123]

Yikes, I've just realised how long it is since I was really into batch files...

something like

IF filesize(data.xml) < 20k then erase data.xml

slightly better version that doesn't need separate restorexml.cmd file.
btw: this script is designed to reside in the xmltv folder

Code:

rem give wireless card a chance to wake up (optional)
sleep 30

echo. >> r:\temp\syslog.txt
echo. >> r:\temp\syslog.txt
echo Wake up to download epg on %date% at %time% >> r:\temp\syslog.txt
echo ----------------------------------------------------- >> r:\temp\syslog.txt

copy data.xml data.old

ping www.birtles.org.uk
IF ERRORLEVEL 1 goto FAIL

XmltvConsole.exe
rem if resulting data.xml file < 5000 bytes abort
for %%R in (data.xml) do if %%~zR lss 5000 goto NORT ELSE echo epg downloaded ok >> r:\temp\syslog.txt

"C:\Program Files\devnz\gbpvr\GBPVR.exe" -OnlyEmptyEPG
"C:\Program Files\devnz\gbpvr\GBPVR.exe" -OnlyUpdateEPG

goto END

:FAIL
rem you decide what you want to do if www.birtles.org.uk is not available. me I usually suspect my flakey usb wireless card, schedule a rerun of this cmd file and reboot the pc
goto END

:NORT
echo XMLTV could not be downloaded from the RT site. Restoring previous xml file >> r:\temp\syslog.txt
copy data.old data.xml

:END

gEd,

ping http://www.birtles.org.uk
IF ERRORLEVEL 1 goto FAIL

Err. surely you want to test against radio times not the birtles website. in my script, I'm checking against http://www.radiotimes.com

[gEd]

fair point! - Actually I had added the ping to check that the USB wi-fi device was working rather than that the rt site was up but I will update my script.

cheers

And standby for the change to PVRX2.EXE from gbpvr.exe.

Also thanks for the batch file - works a treat, although not gone into error mode yet as far as I can tell.

Sorry for being dumb, but just stumbled across this thread - am i right in thinking that, if I have the following file run daily at 1am (scheduled tasks), then it will update (full update) the epg, if i am connected to the net. I the pc is not connected, then it won't do anything (i.e. wont overwrite the epg with blanks)

I save the following .bat file in the xmltv folder, and point GBPVR to the data.xml file found there:

Code:

echo. >> syslog.txt
echo. >> syslog.txt
echo Wake up to download epg on %date% at %time% >> syslog.txt
echo ----------------------------------------------------- >> syslog.txt

copy data.xml data.old

ping www.radiotimes.co.uk
IF ERRORLEVEL 1 goto FAIL

XmltvGUI.exe /Grab /Silent /d7
rem if resulting data.xml file < 5000 bytes abort
for %%R in (data.xml) do if %%~zR lss 5000 goto NORT ELSE echo epg downloaded ok >> syslog.txt

"C:\Program Files\devnz\gbpvr\GBPVR.exe" -OnlyEmptyEPG
"C:\Program Files\devnz\gbpvr\GBPVR.exe" -deletependingrecurring
"C:\Program Files\devnz\gbpvr\GBPVR.exe" -OnlyUpdateEPG

goto END

:FAIL
rem Dont want anything to do here really - just rerun this file tomorrow
goto END

:NORT
echo XMLTV could not be downloaded from the RT site. Restoring previous xml file >> syslog.txt
copy data.old data.xml

:END

Thanks

Yup, should do the job - with one condition - you would have to setup xmltvgui beforehand to select the stations and options that you want in the xml file.

[gEd]

you might want to remove the other reference to r:\temp

my update section now looks like this.

"C:\Program Files\devnz\gbpvr\GBPVR.exe" -OnlyEmptyEPG
"C:\Program Files\devnz\gbpvr\GBPVR.exe" -deletependingrecurring
"C:\Program Files\devnz\gbpvr\GBPVR.exe" -OnlyUpdateEPG

deletependingrecurring removes all the scheduled recordings. they get re-added again (by updateepg i think). this is to fix problems that can occasionally occur when they change the start times of a show.
