XviD Second Pass With FFMPEG

[BTJustice]

Ok I figured out the config.xml could be edited to allow a .bat file to run to do second pass...

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

So I made a .bat file called XviD 2-pass.bat and saved it to C:\Program Files\Devnz\GBPVR\Third Party\ffmpeg

Here is the code in it...

-ab 128k -ac 2 -acodec mp3 -deinterlace -f avi -qscale 7 -pass 1 -threads 2 -vcodec xvid -vtag XVID
-ab 128k -ac 2 -acodec mp3 -deinterlace -f avi -qscale 7 -pass 2 -threads 2 -vcodec xvid -vtag XVID

BUT...

Something is not right as it doesn't work in that .bat file. What am I missing?

Is it me that don't get it, or is it missing a call to the actual FFMPEG.EXE at the start of each command line?

[BTJustice]

config.xml doesn't have the command for FFmpeg in it either for the different conversion types so I didn't put it in the .bat based on that.

config.xml doesn;t have the precise command to launch ffmpeg, only the parameters that will be passed to it.

in the bat file you will need the exact command to run ffmpeg such as this

"c:\Program Files\devnz\gbpvr\Third Party\ffmpeg\ffmpeg" -y -i %1 -ab 128k -ac 2 -acodec mp3 -deinterlace -f avi -qscale 7 -pass 1 -threads 2 -vcodec xvid -vtag XVID "%~dpn1.avi"

(but exactly like this as I think the first pass may need to write out to a temp file, I'm not really sure)

That's what I asumed, when you create a .bat file you're on your own and must supply the exact command to launch ffmepg. I would guess that the parameters from config.xml would be passed to the .bat file as %1 %2 %3 and so on... Right?

[gEd]

No, I don't think so (but it could be tested).

If you want gbpvr to launch a bat file, it will probably pass the filename as %1 but the rest of the parameters should be hard coded in the bat.

I am still not having much luck with the XviD 2-pass code.

I have this in config.xml...

Code:

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

And this as "XviD 2-pass.bat" which is saved in "C:\Program Files\Devnz\GBPVR\Third Party"...

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.avi
"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 nul.avi

I am not seeing what I am doing wrong. Any ideas?

I am still not having much luck with the XviD 2-pass code.

...

Code:

"C:\...\ffmpeg.exe" ... -pass 1 -threads 2 -vcodec xvid -vtag XVID [B][color=Red]nul[/color][/B].avi

Never try to use nul as a filename in DOS based systems, not even with an extension. It is treated as the null device, so your first pass writes directly in to the trash can.

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 auto -vcodec xvid -vtag XVID TEMP.avi
"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 auto -vcodec xvid -vtag XVID "%~dp1%~n1.avi"
DEL TEMP.avi

This doesn't seem to work either.

Just my 2cts: shouldn't the 2nd commandline point to the temp.avi (the output of the 1st commandline) instead of to %1(the original recording)?
