Using ParallelProcessing & PostProcessing together.

[Jim_]

I've seen this come up from time to time, so I thought I'd share my batch file mods.
Adding these commands will allow you to have a PostProcessing.bat, and still use comskip "real-time" in ParallelProcessing.bat.
PostProcessing will remain idol, until parallel processing has finished.

I’ve also included two versions of my PostUpdateEPG.bat,
I compact my gbpvr.mdb every evening (after the EPG update) using gbpvr_compact.exe.
Using “all” the included batch file mods, GBPVRRecordingService will only be restarted (and gbpvr.mdb compacted) if nothing is being recorded or post-processed.

ParallelProcessing.bat

Code:

C:
cd "C:\Program Files\devnz\gbpvr"
echo %2 >"%~n1.REC"
echo %2 >"%~n1.PaP.REC"
REM *** The lines above are the first lines in ParallelProcessing.bat ***

REM *** Channels W/O Commercials ****
REM if "%2" == "13" goto end:
REM if "%2" == "14" goto end:
comskip %1


REM *** The lines below are the last lines in ParallelProcessing.bat ***
:end
del "%~n1.REC"

PostProcessing.bat

Code:

C:
cd "C:\Program Files\devnz\gbpvr"
echo %2 >"%~n1.PoP.REC"
DEL "%~n1.PaP.REC"
:start
Timeout.exe 5
IF EXIST "%~n1.REC" goto start:
REM *** Start Normal PostProcessing.bat Operation ***


REM *** End normal PostProcessing.bat entries ***
DEL "%~n1.PoP.REC"

UpdateEPG.bat

Code:

C:
cd "C:\Program Files\devnz\gbpvr"
del "C:\Program Files\Devnz\GBPVR\*.REC"
REM *** The lines above are the first lines in UpdateEPG.bat ***

PostUpdateEPG.bat (compact after every EPG update)

Code:

C:
cd "c:\program files\devnz\gbpvr"
TimeOut 3600
:start
Timeout 60
if exist "*.REC" goto start:
gbpvr_Compact.exe >Compact.log

PostUpdateEPG.bat (compact only if nothing is being recorded or processed)

Code:

C:
cd "c:\program files\devnz\gbpvr"
TimeOut 3600
if not exist "*.REC" gbpvr_Compact.exe >Compact.log

Very slick! Does the compact program work on the new SQLite DB?

Thanks,

gbpvr_compact.
I don't believe so, but I'm not sure if the SQL database will need compacting anyway?
Gbpvr_compact is a UncleJohnsBand utility, should probably ask him if it needs updating for v97. When I tried v97.7 the access db was growing rather quickly, so it would be worth having again.

I've updated the first post because I forgot to include the UpdateEPG.bat modification.
It deletes stray *.REC files that are left behind if a recording is canceled before it completes.

I haven't moved to 97.07 yet, but hope to very soon. After waiting for the software recorder plugin to be converted, now I am wondering if a maintenance release will be coming soon so that I do not have to track down all the patches. It may be that the SQLite DB cleans up after itself better.

I am using the 97.7 version for some time now and the SQL database stays constantly around 1.2 mB. I have the impression it makes GBPVR way more responsive. No need for databasecompression it seems.

Thought I’d share two more processing mod’s I’ve been using for a while now.
A link for TimeOut.exe is in the first post.

The first one, used in PostProcessing.bat will delay RenameRecording until the file isn’t in use by GBPVR. This eliminates a problem where the file isn’t renamed (RenameRecording errors out) if you’re watching the show when postprocessing.bat is called.

PostProcessing.bat

Code:

:rename
timeout 30
move "%~dpnx1" "%~dp1-%~nx1"
if %ERRORLEVEL% == 1 goto rename:
move "%~dp1-%~nx1" "%~dpnx1"
del "%~dpn1.logo.txt"
RenameRecording -t %1 > rename.log

The ParallelProcessing.bat mod below will allow you to watch the commercials in a selected show, on a specific channel, while avoiding commercials on all the other shows on that channel. I use this one because I like watching “hobby” related commercials, but didn’t want to disable commercial detection for everything on that channel.

Your ComSkip files should be placed in a “Comskip” folder under “devnz\gbpvr” to use this mod. Each time you watch a show, the batch will add a txt file for that show in a “Processed” folder. If you decide you want to watch commercials for a show in the future, just move the appropriate txt file to the “Exclude” folder.
Or create a txt file in the Exclude folder using this example:
GunTec TV (CH-31).txt

ParallelProcessing.bat

Code:

%SystemDrive%
cd "%ProgramFiles%\devnz\gbpvr\comskip"
REM *** Exclude these shows from ComSkip processing ***
IF NOT EXIST "Exclude" MD Exclude
IF NOT EXIST "Processed" MD Processed
for /f "tokens=1 delims=_" %%a in ("%~n1") do SET Exclude=%%a (CH-%2).txt
IF EXIST "Exclude\%Exclude%" echo %date% %Time%>>"Exclude\%Exclude%"
IF NOT EXIST "Exclude\%Exclude%" echo %date% %Time%>>"Processed\%Exclude%"
IF EXIST "Exclude\%Exclude%" GOTO end:
comskip %1
:end

I'm including this from post another thread. Because transcoding "selected" shows is a frequent request.

The problem there is I do NOT want to transcode every show I record. Only select ones.
<snip>

Adding this to your PostProcessing.bat will allow you to process only the (Name & Channel-specific) shows you select.

It will collect show names after they finish recording, in the “Exclude” folder.
If you want to process a show the next time its recorded, simply move its "txt" file from the Exclude folder to the “Process” folder. Or you can create the "TVShow (CH-#).txt" file manually after seeing a couple of examples.

If you prefer, you can test drive it. It wont do anything but collect show titles for future use, until you add a command to process, and place a "TVShow (CH-#).txt" file in the "process" folder.

PostProcessing.bat

Code:

CD /d “C:\Program Files\devnz\gbpvr”
REM *** Process specific shows ***
IF NOT EXIST "Exclude" MD Exclude
IF NOT EXIST "Process" MD Process
for /f "tokens=1 delims=_" %%a in ("%~n1") do SET TVShow=%%a (CH-%2).txt
IF EXIST "Process\%TVShow%" echo %date% %Time%>>"Process\%TVShow%"
IF NOT EXIST "Process\%TVShow%" echo %date% %Time%>>"Exclude\%TVShow%"
IF NOT EXIST "Process\%TVShow%" GOTO end:

or you could just replace 'comskip %1' with 'start /w comskip %1' and it won't exit that batch till comskip is done, [which presumably means the recording is also done] and you could add the post batch filename to the end of the parallelprocessing.bat
and any other commands in there adjust to start with start /w ..

like:

start /w comskip %1
post.bat

simplicity rules!

Wouldn’t an even simpler way be to place all the commands in ParalleProcessing.bat without the “start /w” command?

Some people like running cpu intensive (and other) commands using postprocessing.bat because post’s are called after the recording is complete, only one at a time, one after the other. But Post is called immediately after the recording finishes, and does not wait for parallel to close.
