if I am on the right track it looks like the file name in the tmp dir is to264-xxxxx\r.sed\r

so lets see if I can figure this out :D

I think I just got it. I think you saved the script or edited it on a windows
machine and then transferred it to linux? I think the '\r' is the visual
representation of the return character. Dos/windows uses carriage
return and line feed both, but unix only uses one. In the linux
command line edit the file in binary mode:

vi -b to264

Then use the following to remove all the return characters

:1,$s/.$//

this will take the last character off every line in the file.

well I give up .. I can not see a difference between the to770 and the to264 file except for the FPS check (which is ok since I put it in the to770 script) and the "MYSQL="/usr/bin/mysql -u root"" other than that the to770 runs and the to264 does not. C'est La Vie, I have a gremlin somewhere that just would go away. So I will just use the to770 script and put the FPS check in and mod the mencoder settting

Try editing it with "vi -b" and see if there are special characters on the end of each line. I might have accidently done it on my end.

Great script :D

I had a little trouble getting it to work but once I did SWEET

FYI I am running R5F27 with the mplayer upgrades. I added the permissions and commands to the job list but when I ran the job I would get a 0 byte file.

To get mine to work I had to add a bitrate to the first mencode line, there was a ratecontrol error in debug. I also remove the me=2 option in the second mencode line, the debug file stated that me was an unknown option.

I also replaced aspect with ...
-vf crop=712:456:4:6,lavcdeint,spp,scale=320:240 (personal preference on the video size and the debug said something about using -vf spp,scale)

so the 2 mencode lines look like this for me
Code:
$MENCODER $REC_DIR/$1 $AUDIO  -ovc x264 -x264encopts bitrate=1800:turbo=1:subq=1:frameref=1:bframes=2:pass=1 -vf crop=712:456:4:6,lavcdeint,spp,scale=320:240 $EDL -o "/dev/null"

$MENCODER $REC_DIR/$1 $AUDIO  -ovc x264 -x264encopts bitrate=1800:subq=4:8x8dct:frameref=3:bframes=2:b_pyramid:weight_b:pass=2 -vf crop=712:456:4:6,lavcdeint,spp,scale=320:240 $EDL -o "$OUT_FILE"


I still have to play with the biterates I used to use 1500 on the first pass and 500 on the second pass, so I will try that out and see how it looks.

Oh forgot to mention that is for the to264 script


Did you test out the different bitrates? How did they look? I got my setup working with your mencoder lines and it's working great. I'm using the latest sync to svn mplayer.

I've always just left the resolution as it comes from the encoding device except for the Nokia 770 script. I haven't tried changing it. The nokia doesn't
have enough cpu power to play a high bitrate movie. They look great
on it's screen though. Just as a guess if you want smaller files I don't
think it will be a problem.

Here are my mencoder lines... I add threads and some deinterlace parameters.

# deinterlace options
DEINT="-yadif=3 -mcdeint"
AUDIO="-oac mp3lame -lameopts abr:br=128"
EDL="-edl $TMPFILE.edl"

# run mencoder to do conversion
# NOTE this runs mencoder at high quality with very low priority. It won't be fast but it will not mess
# up recordings by sucking up all the cpu time.
# pass 1 - run at lower quality for motion estimation
$MENCODER $REC_DIR/$1 $AUDIO -ovc x264 -x264encopts bitrate=500:threads=2:turbo=1:subq=1:frameref=1:bframes=2:pass=1 -vf yadif=3,mcdeint -aspect 4:3 $EDL -o "/dev/null"

$MENCODER $REC_DIR/$1 $AUDIO -ovc x264 -x264encopts bitrate=1800:threads=2:subq=4:8x8dct:frameref=3:bframes=2:b_pyramid:weight_b:pass=2 -vf yadif=3,mcdeint -aspect 4:3 $EDL -o "$OUT_FILE"
