New wiki entry: RecoverRecordings

[pBS]

Since my old recover recordings.bat file got deleted in forum maintenance, i made a wiki entry for a more premanent home..

It basically imports lost recording's metadata from the metadata.xml on each file and makes a recording-dump.xml file and mports that into pvrx2...A poor man's Vidimport... The data will look just like it did before as it's same data as it used to be.

A nice new feature is that i added is that it adjusts paths on the fly, so if you for example, changed recording dirs, it will adjust the filename inside to the new path automatically..

run from a network drive, it will make them network paths...

Enjoy, for times of crisis...

Cries of Joy - thanks for this. (now how to store metadata on networked drives???).

[pBS]

hmmm, what do you mean? you can save shows to network drives and they will get metadata.. [not sure about a NAS tho, may need to be a windows box]

I was thinking of non-NTFS networked drives like nas, linux, PCH or whatever.

Out of curiosity, does gbpvr actually use the metadata for anything ??, if not, I wonder why it was generated for in the first place ??

[pBS]

it's just a backup for the original data...
but it does get used for info display in video library...

to use on a nas non-ntfs drive, convert to a mymovies style xml and store alongside the movie..

I had a few minutes spare so I thought I would give it a go.

This doesn't work for me....assuming I am doing it right....from my development PC I copied the batch to the recording directory on my server & then ran it from my development PC but it did nothing apart from open a dos window & then close very soon afterward?

Then I tried running it from the server & this time it created a recording-dump.xml but it never finished collecting all the data & seemed to die when it got to the directory "Immortal (Ad Vitam)" or the recording "Immortal (Ad Vitam)_20091208_02200410.ts" I assume it didn't like the "()"?

yea, i wouldn't recommend it with renamed files...pretty sure those chars are not dos compatible..tho i may be able to get around it..

try this one, no adjustments..
i just wanna see if it works this way..

Code:

@echo off
setlocal ENABLEDELAYEDEXPANSION
echo.
echo. Generating Recording Import data for all .mpg's in
echo.     %~dp0recording-dump.xml
echo.
echo ^<?xml version="1.0" encoding="UTF-8"?^> > %~dp0recording-dump.xml
echo ^<recordings^> >>%~dp0recording-dump.xml
FOR /R %~dp0 %%f IN (*.mpg *.ts *.dvr-ms *.avi) DO (call :extract "%%~f")
echo ^</recordings^> >> %~dp0recording-dump.xml

echo.
echo Done.
echo.
echo Hit any key to import into database or 'Control-c' to exit and edit recording-dump.xml.
pause
for /f "usebackq skip=4 tokens=1,2,3,* " %%a in (`reg query hklm\SOFTWARE\devnz /v "GBPVR InstallDir"`) do set gbpvrdir=%%d
"%gbpvrdir%pvrx2.exe" -import:"%~dp0recording-dump.xml"
echo Importing....
echo Done.
goto :eof

:extract
echo ""
for /f "usebackq tokens=* skip=1 delims=*" %%p in ("%~1:metadata.xml") do echo       %%p >> "%~dp0recording-dump.xml"
goto :eof

[pBS]

hmm,got it working by using quotes...now just need to find out if that messes anything up..

It isn't a renamed file, that is as it is when it was recorded by GB-Pvr.

Yep that one didn't die & went right through & it also ran when I invoked it across the network but it didn't put network paths in the resulting recording-dump.xml.

Interesting when I was running it from my development PC it was a lot slower & I was able to see a few couldn't find metadata files error messages while it was running....might be nice if it could log these so you know they haven't been imported if possible?

[pBS]

ahh,after some major tweaking, fixed...

but this one won't be as bulletproof as it makes some assumptions about the order of lines in xml..
[line 3 has to always be filename]
problem with logging is, you can't test for presence of an alt-stream, so hard to log..
the one i had on here that got deleted had logging...

Code:

@echo off
echo.
echo. Generating Recording Import data for all .mpg's in

echo Importing....
echo Done.
goto :eof


:extract
for /f "usebackq tokens=* skip=1 delims=*" %%a in ("%~1:metadata.xml") do if "%%a"=="" goto :not  
for /f "usebackq tokens=* skip=3 delims=*" %%b in ("%~1:metadata.xml") do if not "%%b"=="" echo  ^<Recording^> >> "%~dp0recording-dump.xml" && goto :file
:file

:next
for /f "usebackq tokens=* skip=3 delims=*" %%p in ("%~1:metadata.xml") do echo  %%p >> "%~dp0recording-dump.xml"
goto :eof

:not
echo No metadata for %1

now should be safe for any filename that can exist on disk...network access too..
[i could echo out the name, just not while in a ( ), so had to do it all separately..]
