you could also use ffmpeg

ffmpeg -i video.flv -ab 56 -ar 22050 -b 500 -s 320x240 test.mpg

#

You realize that list of commands you gave in ffmpeg is without SOUND and your VIDEO OUTPUT is TERRIBLE by any standards this one on the page doesn't have that problem and his doesn't need 30 slash commands to make a worse video with no sound.

#

OK, I'm trying this ffmpeg code (and others in the replies) and still not getting satisfactory output. I either get no sound, no picture or error on my dvd player. Most all files work with Win Media Player before burning to a disc.

I've got a Philips DVD player DVP3140 (DivX decoder) and I'm ripping the youtube vids with keepvid.com. Anyone else using a similar dvd player/software and having problems or can give me some help?

ffmpeg -i youtube.flv -ar 48000 -ac 2 youtube.avi

#

very useful, thanks

#

yeah, thanks a lot. this is the first commmand that worked with me so far. although i got better results with changing the channels (that is, the -ac parameter) to 1.

#

DivX has their own YouTube alternative. <a href="http://stage6.divx.com/" title="divx.com">http://stage6.divx.com/</a divx.com> If you're looking for higher (video) quality videos, you may want to take a look at it. They're also natively DivX.

#

changing the media format doesn't improve the quality of the content. It still (generally) sux.<nobr> <wbr></nobr>:)

#

think outside the box, how about playing those files on your xvid dvd player..

#

true I used to us veoh until they changed over to sucky low flv files

#

ffmpeg2theora is a simple app that works well for most files

#

Please don't spread this DivX nonsense on a public website. You obviously either don't understand basic terms (the difference between software and specification, or codec and format), or you're intentionally lying because of the massive ubiquity of the "DivX myth", which is irresponsible.

The compression you're using is called MPEG-4 ASP (MPEG-4 is a standard developed by MPEG) and the codec (i.e. software) you're using for converting it to this format is FFmpeg (libavcodec) MPEG-4. It has absolutely nothing to do with DivX, which is nothing else than a brand name of a commercial closed-source MPEG-4 codec (a piece of software, not a format) that you don't use.

XviD is not a format either, XviD is a name of yet another MPEG-4 codec, which is open-source (FFmpeg/libavcodec is open-source, too). XviD is a piece of software, it also encodes and decodes MPEG-4 ASP video, just like all other MPEG-4 ASP codecs.

#

They have different FourCC values. So while you're right, when you tell Mplayer to write to Xvid or DivX (there's a -xvid option for Mplayer. For Divx you are basically telling it to use mp4 directly), you ARE specifying a different mpeg4 fourcc

Dude (or dudet as it may be), word of friendly advice? Stop yourself!

There are some interesting articles on your sight (I read the Window's boot one and the WTC discussion), but after seeing you spam your sight in the comment section on every open source article I've read in the last little bit, I don't care anymore.

Frankly, I'm starting to hope a blackhole pops into existence in close proximity to your harddisk spindle.

PS: And what's with the bolding? You've got me worried, are we only days away now from being ALL CAPITALS?!?

Why do you continually persist in spamming about your site?

#

The Philips DVP642 doesn't seem to recognize the fourcc codes that mencoder puts in for xvid or ffmpeg-mp4, even though the codecs should be decodable.

adding "-ffourcc=divx" to the options seems to take care of the problem. I've converted xvid and ffmpeg-mpeg4 videos with a simple "mencoder -ovc copy -oac copy -ffourcc=divx" and they play fine, so, like "IE only" websites that actually look fine when you spoof the user agent, spoofing the "fourcc" code appears to work for some players.

Hi, made some little changes to get the script working with filnames containing spaces.



(The original code works as well but saves files containing spaces in name as ".avi" so the file will be overwritten when using a list of filenames to convert and in the end just you'll just get the last file)



May I'll also make an -dir option wich allows to convert all files in a specified directory.



So here the changed version:

<tt>#!/bin/sh

if [ -z "$1" ]; then
  echo "Usage: $0 {-divx|-xvid} list_of_flv_files"
  exit 1
fi

# video encoding bit rate
V_BITRATE=1000

while [ "$1" ]; do
  case "$1" in
    -divx)
      MENC_OPTS="-ovc lavc -lavcopts \
        vcodec=mpeg4:vbitrate=$V_BITRATE:mbd=2:v4mv:autoa<nobr>s<wbr></nobr> pect"
     <nobr> <wbr></nobr>;;
    -xvid)
      MENC_OPTS="-ovc xvid -xvidencopts bitrate=$V_BITRATE:autoaspect"
     <nobr> <wbr></nobr>;;
    *)
      if file "$1" | grep -q "Macromedia Flash Video"; then
           BasName=`basename "$1"<nobr> <wbr></nobr>.flv`
           NewName=`echo "$BasName" | tr ' ' '_'`
           mencoder "$1" $MENC_OPTS -vf pp=lb -oac mp3lame \
             -lameopts fast:preset=standard -o \
             "${NewName}.avi"
           mv ${NewName}.avi "${BasName}.avi"
      else
        echo "$1 is not Flash Video. Skipping"
      fi
     <nobr> <wbr></nobr>;;
  esac
  shift
done</tt>

So how would you change the aspect ratio? When I was using a Windows converter I would change it to 640x480 so that I would work on my Archos player. I think i know where to modify it, but I don't Know what I'm supposed to type.

#

I munged in -o copy instead of the lame code and it ended up having sync drift. Maybe it's a local problem, but specifying lame seems to avoid this problem.

#

thanks for the tip, but it didn't work out so well for me. after converting, seek now works but the audio goes out of sync if you use seek.

#

Nice post. If you want to convert to mpg, mp3 and dvd there are details here <a href="http://zztools.blogspot.com/" title="blogspot.com">http://zztools.blogspot.com</a blogspot.com>

alright, spamming for a windows program on a linux website. great idea. furthermore, you want us to pay for that when quite obviously this article is talking about how to do that without paying a cent, and using a much more powerful/flexible method.

#

Correct me if I'm wrong, but you are re-enconding an already high compressed video in lossy data compression <a href="http://en.wikipedia.org/wiki/Lossy_data_compression" title="wikipedia.org">http://en.wikipedia.org/wiki/Lossy_data_compressi<nobr>o<wbr></nobr> n</a wikipedia.org>, thus loosing quality even further, right?

#

In the<nobr> <wbr></nobr>.flv container the audio stream is usually mp3 already and is usually encoded with a low bitrate such as 96 or 64.

So why bloat it by recompressing it, when you can simply use MEncoder's stream copy:

<tt>-oac copy</tt>

Cheers,

Hi there!
it didn't work with that options in nokias phones. I get an error with my s60 in smartmovie complaining about 'bad AVI'. It worked out with this script. In case someone find this useful:

#!/bin/sh

#mencoder -of avi -ovc xvid -xvidencopts bitrate=500:interlacing -afm ffmpeg -af resample=16000,channels=1 -oac mp3lame -lameopts cbr:br=64:mode=3 -noskip -vop scale=208:176 flv/tAsOfqCy4A0.flv -o prueba.avi



if [ -z "$1" ]; then

  echo "Usage: $0  list_of_flv_files"

  exit 1

fi



# video encoding bit rate

V_BITRATE=50

while [ "$1" ]; do

  mencoder -of avi -ovc xvid -xvidencopts bitrate=$V_BITRATE:interlacing -afm ffmpeg -af resample=16000,channels=1 -oac mp3lame -lameopts cbr:br=64:mode=3 -noskip -vop scale=208:176 "$1" -o "`basename $1 .flv`.avi"

shift

done

Save it as flv2avi.sh and
$chmod 755 flv2avi.sh

#

I'm using this script as is provided on this page, and I'm getting some serious sync drift between audio and video. Are there options to correct for this ? When mencoder is doing it's business some skipped frame messages appear, by the way. This occurs even without seeking through the file.

How to convert YouTube videos to DivX or XviD

#

Great article!
This is what I love about open source, with a little information and initiative
[Modified by: Anonymous on November 20, 2007 02:12 AM]

Have tried using the Mencoder script for conversion of Youtube vids, but unfortunately, despite having everything correctly installed, from ffmpeg to lame, and using a prebuilt version of Mencoder (note I have also tried this with a home compiled version of Mencoder as well), it causes Mencoder to do one of 2 things:

It either generates a file which has a file size of absolutely sod all, or
It causes Mencoder to Segfault (SIGSEGV / Signal 11).

I am running Mandriva 2007.0 on a custom system (i686/libc6)

Any more suggestions: Can't dl them straight from net as no access in home. Need to convert what I already have so I can watch them.

#

This is what happened when i tried to convert using the command flv2avi -divx <filename>.flv

MPlayer was compiled without libmp3lame support.
-lameopts is not an MEncoder option

Im a noob and i dont know what that means.

does anyone know?
