thumbnails from video files

[zehd]

ahhh,it's cuz you had the vframes 1 after the input file..
as i understand it, the new ffmpeg syntax changed to having all parameters before their intended target, so the input options have to be before the -i and all output opts just before the output, or at least has to be after the input..

[input opts] -i file [output opts] outputfile
so the vframes needs to be before the input, and sizing after the input..

glad it works well for you now..really comes in handy..

My gawd man, do you have a life?

(like I'm really one to talk)

It's something that I never knew or paid attention to. I'll be updating my commandlines. Thanks

of course not...especially now that my car is in the shop...again...grrr..
had someone replace the clutch, and it would have helped if they knew what they were doing, so they screwed my gearbox up too..
so back into another shop to fix that...

i knew i shoulda just done it myself..

[and that batch didn't take 5 mins, i already had it worked out for showburner..hehe]

usage: save as snap.bat and type [snap.bat filename.mpg]

Would this work, if I simply put it into my PostProcessing.bat file?

Would it be a simple copy-paste?

[gkovacsp]

Appearantly it does, but it is not executed, if I STOP the recording, only if it ends naturally.

[gkovacsp]

Now I may look stupid after my two previous posts, but the previews are not created automatically after a recording, if I copy/paste the script lines into the postprocessing.bat file's end.

Anyone any idea, why doesn't it work?

here is the complete script:

Code:

@echo off Rem PostProcessing.bat Rem This script will be run automatically by GBPVR when found after a recording is finished Rem To enable it put this file inside your GBPVR default program directory (C:\Program Files\devnz\gbpvr\) Rem together with Comskip.exe, Comskip.ini and Comskip.dictionary Rem The script is called with two parameters Rem %1 is the fully qualified name of the recorded mpeg file. Rem %2 is the channel number of the recording echo Postprocessing.bat invoked on %1 recorded from channel %2 >>postprocessing.log Rem The part below can be used to not run Comskip on certain channels, please modify for your conveniance. Rem The channel numbers that should be skipped are the numbers between the double quotes (""). Rem You can add "if" lines as much as you want Rem To disable this behaviour use channel numbers outside the normal range, put a "rem" before the "if" or delete the "if" lines Rem list of channels to not run comskip on rem if "%2" == "27" goto eof rem if "%2" == "36" goto eof Rem this trick also makes it possible to have dedicated comskip.ini file for certain channels. rem if "%2" == "79" goto channel79 rem if "%2" == "72" goto channel72 rem if "%2" == "65" goto channel65 Rem use the default comskip.ini for all other channels goto generic :channel79 comskip --ini=channel79.ini %1 goto continue :channel72 comskip --ini=channel72.ini %1 goto continue :channel65 rem This is an example of how to reuse a previously learned logo to prevent Comskip from learning the wrong logo comskip --ini=channel65.ini --logo=channel65.logo.txt %1 goto continue :generic Rem The actual run of Comskip. Only one parameter, the name of the mpeg file to process. Rem Comskip will read its settings from the Comskip.ini found in the same directory as Comskip.exe Rem Both are supposed to be in the GBPVR default program directory. (C:\Program Files\devnz\gbpvr\) comskip %1 :continue Rem Once the commercials have been identified you can run comclean to delete the commercials from the recording. Rem Do this only when you are not using the Skip function in the GBPVR viewer. Rem To enable comclean remove the word "Rem" from the following line. rem call comclean %1 :eof rem auto creare snapshot about movie @echo off cls rem Set "line" to comskip break # you want, starting at line 3 for first commercial..4 for second,etc.. set line=4 set seconds=120 if exist "%~dpn1.txt" for /f "usebackq tokens=1,2 skip=%line%" %%c in ("%~dpn1.txt") do ( :: Adjust below line for exact snap time, i use + 2 as + 0 usually is black frame.. set /a seconds= %%d * 100 / 2997 + 2 goto :next ) :next echo. Echo Snapping from %seconds% into movie. echo. "C:\Program Files\gbpvr\Third Party\FFmpeg\ffmpeg.exe" -y -ss %seconds% -vframes 2 -i "%~1" -f image2 "%~dpn1.jpg" echo. echo Done! "%~dpn1.jpg" %seconds% rem START "image" "%~dpn1.jpg" rem use the START image line to auto-view it afterwards...

My GBPVR is in "C:\Program Files\gbpvr".

In case I put it in a separate bat file and drop a video file on it, then the preview is created.

I'm puzzled.

Not sure about your setup, but if it is like mine, then it looks like your path may be wrong:


"C:\Program Files\gbpvr\Third Party\FFmpeg\ffmpeg.exe"

should be:

"C:\Program Files\devnz\gbpvr\Third Party\FFmpeg\ffmpeg.exe"

[EDIT]: just read the bottom of your post, looks like the directory is ok,

You may have to log some detail to figure out what's going on.

I would suggest the following changes:

Code:

"C:\Program Files\gbpvr\Third Party\FFmpeg\ffmpeg.exe" -y -ss %seconds% -vframes 2 -i "%~1" -f image2 "%~dpn1.jpg" [B]>>postprocessing.log 2>&1[/B]

This will cause all the output from the FFMPEG program to be put into postprocessing.log thus allowing you to see better what is going on.

I downloaded ffdshow and installed it separately from gbpvr, I have the screenshots now.

I'll see if it keeps on working.

Thanks for the help on the logging, that might be good later.
