great info, thanks for the post.

someone posted this before the server crashed, so I'll post it again because it works fine for me:

Just install memcoder and post this into your terminal:

MOVIENAME.avi -idx -noodml -ofps 20 -vf scale=320:-2,expand=:240:::1,crop=320:240,rotate=1 -ovc lavc -ffourcc XVID -lavcopts vcodec=mpeg4:vbitrate=384:vmax_b_frames=0:vhq -sws 9 -srate 44100 -oac mp3lame -lameopts cbr:br=128:mode=0 -o CONVERTED_MOVIENAME.avi

Reduce the bitrate if you're having problems with audio being not in sync.

... Not working

I typed :

mencoder /media/mymoviefolder/mymoviename.avi -idx -noodml -ofps 20 -vf scale=320:-2,expand=:240:::1,crop=320:240,rotate=1 -ovc lavc -ffourcc XVID -lavcopts vcodec=mpeg4:vbitrate=384:vmax_b_frames=0:vhq -sws 9 -srate 44100 -oac mp3lame -lameopts cbr:br=128:mode=0 -o /media/mymovieoutput/mymovieoutputname.avi

And the only thing I have is an arrow > not anything more ?

The input file was a divx.



Can I use Transcode ? Do anybody know the commands to use ? If not, I will try to look for it myself but it might take several time :D

I looked for a good frontend for mencoder under ubuntu (edgy)... Acidrip seem useful but has not all the options that I need...
Any ideas ?

Here did I found an answer to try


mencoder /media/wheremyfileis.avi -quiet -vc ffmpeg12 -ofps 20 -vf scale=320:240:0:0:0.00:0.75,expand=320:240,rotate= 1 -ovc xvid -xvidencopts profile=dxnhtntsc:cartoon:zones=0,w,1.0:bitrate=38 4:pass=1 -oac mp3lame -lameopts cbr:br=128 -info name=Film_Name -o /media/wheremyoutputwillbe.avi

It works, but I obtain :
Forced video codec: ffmpeg12
Cannot find codec matching selected -vo and video format 0x44495658.
Read DOCS/HTML/en/codecs.html!

... So will I :)

Thanks for reposting this, it works great for me in Fedora Core 6.

For video this works beautifully but the sound has a terrible warbling fault (that is not present on the source avi). The problem is not a miniplayer one as the output avi has the same warbling when watches using several different players, thus it must be a mencoder conversion issue. Does anyone have any suggestions?

TIA

To (crop) get rid of black bars in widescreen movies:

x = 240 * movie aspect ratio

-vf scale=x:240,expand=:240:::1,crop=320:240,rotate=1

example:
movie aspect ratio is 16/9 = 1.777777778
240 * 1.777777778 = ~427 (must be integer)
mencoder options:
-vf scale=427:240,expand=:240:::1,crop=320:240,rotate= 1

In the Audio Output Codec (-aoc) options I use this and the audio works great!

-oac mp3lame -lameopts cbr:mode=2:br=96 -af resample=44100 -srate 44100

I think you should give a try to the resample/samplerate values...

Also try to decrease video and audio bitrates: if the video bytestream is too demanding the player could render bad video or bad audio (or not render anything at all!) .

Hope this helps!
