XviD Second Pass With FFMPEG

[HtV]

I read some where that you can write the first pass to null.avi, that means it gets deleted right away, because you don't need it anyway.

I am testing null.avi now in the file.

I am not sure why this is not working in config.xml...

Code:

<Conversion name="XviD 2-pass" exe="XviD 2-pass.bat">

[HtV]

I did some testing: I think this should be in config.xml:

Code:

<Conversion name="XviD 2-pass" exe="XviD 2-pass.bat" cmd="{SOURCE_FILE} {DEST_FILE}" targetExtension=".avi"/>

You should leave out the -y-i at the start, the batfile woudn't know what to do with those parameters.

I'm not sure about the null.avi, I used that in my batfile, it didn't write anything afaict, but I couldn't find a logfile either.:confused: FFmpeg was running though

So with the above line in config.xml, the batfile should run.

I run a test on a short recording, it seems to run fine except:
- test.avi and the logfile are created in the gbpvr-dir.
- When the avi was ready, ffmpeg kept running:confused:

But we are getting there.

IT WORKS!!!

-y and -i are legitimate commands for FFmpeg according to the FFmpeg Documentation.

So for those who would like to try this...

1) Save the "XviD 2-pass.bat" file within the attached .zip file in this post to "C:\Program Files\Devnz\GBPVR\Third Party"

2) Open your config.xml file with NOTEPAD in "C:\Program Files\Devnz\GBPVR" and in the <CustomFFmpegConversions> section, add this (make sure to add spaces in front so it lines up with the other conversions listed there...

<Conversion name="XviD 2-pass" exe="XviD 2-pass.bat" cmd="{SOURCE_FILE} {DEST_FILE}" targetExtension=".avi" />

3) Open the CONFIG program by going to START > ALL PROGRAMS > GB-PVR and click on the PROCESSING tab. Select "XviD 2-pass" from the drop down menu for "Auto-Convert MPG..." (I also selected this for DVR-MS and TS) and click OK.

That's it.

On a side note, if you have .mpg recordings you still need to convert, you can go to where they are saved, right-click on them and left-click on OPEN WITH. Browse to "XviD 2-pass.bat" in "C:\Program Files\Devnz\GBPVR\Third Party" and it will convert the .mpg file for you. BE SURE TO UNCHECK THE BOX IN FRONT OF "ALWAYS USE THE SELECTED PROGRAM TO OPEN THIS KIND OF FILE"!!!

The "XviD 2-pass.bat" file will delete your original .mpg file once the .avi XviD file is created. I decided this would be good in order to save hard drive space. If you want to keep your original .mpg files, right-click once on "XviD 2-pass.bat" and left-click on EDIT. Delete the line "IF EXIST "%~dp1%~n1.avi" DEL %1" then re-save "XviD 2-pass.bat".

THANKS TO ALL THAT HELPED WITH THIS ESPECIALLY HtV!!!

I added an exit command to the end of the batfile, that took care ffmpeg keeping running. The batfile now looks like this:

Code:

"C:\Program Files\Devnz\GBPVR\Third Party\ffmpeg\ffmpeg.exe" -y -i %1 -ab 128k -ac 2 -acodec mp3 -deinterlace -f avi -qscale 7 -pass 1 -threads 2 -vcodec xvid -vtag XVID null
"C:\Program Files\Devnz\GBPVR\Third Party\ffmpeg\ffmpeg.exe" -y -i %1 -ab 128k -ac 2 -acodec mp3 -deinterlace -f avi -qscale 7 -pass 2 -threads 2 -vcodec xvid -vtag XVID "%~dp1%~n1.avi"
exit

It doesn't make any difference if you write the first pass to null or null.avi they are written anyway to the gbpvr-dir. But I guess you could add a delete command before the exit command. e.g :

Code:

"C:\Program Files\Devnz\GBPVR\Third Party\ffmpeg\ffmpeg.exe" -y -i %1 -ab 128k -ac 2 -acodec mp3 -deinterlace -f avi -qscale 7 -pass 1 -threads 2 -vcodec xvid -vtag XVID null
"C:\Program Files\Devnz\GBPVR\Third Party\ffmpeg\ffmpeg.exe" -y -i %1 -ab 128k -ac 2 -acodec mp3 -deinterlace -f avi -qscale 7 -pass 2 -threads 2 -vcodec xvid -vtag XVID "%~dp1%~n1.avi"
del null
del *.log
exit

If you want the 1st pass to be written somewhere else you could change that too in the bat-file e.g something like %1first

Code:

"C:\Program Files\Devnz\GBPVR\Third Party\ffmpeg\ffmpeg.exe" -y -i %1 -ab 128k -ac 2 -acodec mp3 -deinterlace -f avi -qscale 7 -pass 1 -threads 2 -vcodec xvid -vtag XVID %1first
del %1first
"C:\Program Files\Devnz\GBPVR\Third Party\ffmpeg\ffmpeg.exe" -y -i %1 -ab 128k -ac 2 -acodec mp3 -deinterlace -f avi -qscale 7 -pass 2 -threads 2 -vcodec xvid -vtag XVID "%~dp1%~n1.avi"
del *.log
exit

I tried this batfile and it worked fine. The temp files were deleted and the avi plays fine.

Changes added to the attached file in my last post.

I did a little new search for the writing to null. Turns out that I had to skip one l :o. So the following batchfile works fine now:

Code:

"C:\Program Files\Devnz\GBPVR\Third Party\ffmpeg\ffmpeg.exe" -y -i %1 -ab 128k -ac 2 -acodec mp3 -deinterlace -f avi -qscale 7 -pass 1 -threads 2 -vcodec xvid -vtag XVID nul
"C:\Program Files\Devnz\GBPVR\Third Party\ffmpeg\ffmpeg.exe" -y -i %1 -ab 128k -ac 2 -acodec mp3 -deinterlace -f avi -qscale 7 -pass 2 -threads 2 -vcodec xvid -vtag XVID "%~dp1%~n1.avi"
del *.log
exit

There is no 1st pass avifile written, just the logfile.

I think this is about as nice as it gets.
If you wanted you could quite easily change the ffmpeg parameters now.

Try the latest .bat in the .zip file above. The first .avi is saved as TEMP.avi which is later deleted after the second pass completes. The original .mpg is also deleted.

[HtV]

I would be careful with the "del %1" command. If for some reason the ffmpeg wouldn't run properly your original file would still be deleted (maybe).:eek: And you would end up with nothing. Maybe you could build in a check if the new avi is there. I've seen that somewhere, some "if ......" command.

If you use my batfile the first pas isn't written at all and therefore doesn't have to be deleted. That's better for the hdd. :-)
