divx2pass.bat

Code:

d:
cd \projectx.old
copy %1 d:\projectx.old\temp.ts
javaw -jar projectX.jar temp.ts
echo %date% %time% %2>> runinst.txt
"D:\Program Files (x86)\Devnz\GBPVR\Third Party\ffmpeg\ffmpeg.exe" -y -i d:\projectx.old\temp.m2v -an -f avi -threads 8 -pass 1 -s 1280x720 -b 3500k -minrate 0k -maxrate 10000k -vcodec mpeg4 -bufsize 1000k -vtag divx nul

del temp.m2v
del *.ac3
del temp.ts
del *.log
rem restore path
cd "\program files (x86)\Devnz\GBPVR"
IF EXIST "%~dpn1.avi" DEL %1
EXIT

This code also records in runinst.txt (projectx directory) when it runs and file name

config.xml trans-code entries. I found if you have to many it gets messed up so I deleted some I do not use.

Code:

<CustomFFmpegConversions>
    <Conversion name="XviD" cmd="-y -i {SOURCE_FILE} -f avi -ab 224k -ac 2 -acodec mp3 -deinterlace -vcodec xvid -qscale 5 -vtag XVID {DEST_FILE}" targetExtension=".avi" />
    <Conversion name="Divx crop analog" exe="acroptop.bat" cmd="{SOURCE_FILE} {DEST_FILE}" targetExtension=".avi" />
    [B]<Conversion name="HD Divx 2-pass" exe="Divx2pass.bat" cmd="{SOURCE_FILE} {DEST_FILE}" targetExtension=".avi" />[/B]
    <Conversion name="DivX" cmd="-y -i {SOURCE_FILE} -f avi -threads 4 -ab 224k -ac 2 -acodec mp3 -vcodec mpeg4 -s 1280x720 -b 5000k -vtag DIVX {DEST_FILE}" targetExtension=".avi" />
  </CustomFFmpegConversions>

HD Divx 2-pass calls the batch file. Projectx corrects errors in the ts file splitting the audio out. You almost always have errors using atsc over an antenna. Then ffmpeg converts the video and audio to avi output.

You need to load java sdk and set the environment variables, java_home and add to the path variable the path to the java bin directory . After setting them you will need to reboot the computer as PVRX2 and associated services seem to read the environment variables at boot time. In the projectx directory you will need to run build. You will see some errors but it still works. The portable compiled projectx.exe does not work for command line options.

This is more streamlined now we don't need to copy ts file to projectx directory. Projectx runs on the recording directory. Also using qmin-qmax to control quality You can adjust these to your liking in the ffmpeg line.

Code:

javaw -jar d:\projectX.old\projectX.jar %1
echo %date% %time% %2 >> d:\projectx.old\runinst.txt
"D:\Program Files (x86)\Devnz\GBPVR\Third Party\ffmpeg\ffmpeg.exe" -y -i "%~dp1%~n1.m2v" -i "%~dp1%~n1.ac3" -ab 128k -acodec libmp3lame -ac 2 -r 30 -async 1 -ar 44100 -f avi -qmax 5 -qmin 3 -threads 8 -s 1280x720 -b 2800k -minrate 0k -maxrate 10000k -vcodec mpeg4 -bufsize 3500k -vtag divx %2
del "%~dp1%~n1.m2v"
del "%~dp1%~n1.ac3"
del "%~dp1%~n1[1].ac3"
IF EXIST "%~dp1%~n1.avi" DEL %1
EXIT

Sometimes there are 2 ac3 streams so the extra delete line. multiple copies of this batch file can be ran simultaneously to convert multiple files at the same time. I've done it but I have not checked if the java will work at the same time yet. I've started one then another but java had completed by the time I ran the second and third copy.

I'm using a compiled ffmpeg-0.5 that I made to test this. The 18695ffmpeg might have trouble with qmin and qmax, but I can't remember for sure if it bombed out sometimes.

ffmpeg-0.5 can be downloaded from http://www.mediafire.com/?an3iyoitttt
