14.6. Encoding with the Video For Windows codec family
Video for Windows provides simple encoding by means of binary video codecs. You can encode with the following codecs (if you have more, please tell us!)
Note that support for this is very experimental and some codecs may not work correctly. Some codecs will only work in certain colorspaces, try -vf format=bgr24 and -vf format=yuy2 if a codec fails or gives wrong output.

The first column contains the codec names that should be passed after the codec parameter, like: -xvfwopts codec=divx.dll The FourCC code used by each codec is given in the parentheses.
An example to convert an ISO DVD trailer to a VP6 flash video file using compdata bit-rate settings:
mencoder -dvd-devicezeiram.isodvd://7 -otrailer.flv\ -ovc vfw -xvfwopts codec=vp6vfw.dll:compdata=onepass.mcf -oac mp3lame \ -lameopts cbr:br=64 -af lavcresample=22050 -vf yadif,scale=320:240,flip \ -of lavf
14.6.2. Using vfw2menc to create a codec settings file.
To encode with the Video for Windows codecs, you will need to set bitrate and other options. This is known to work on x86 on both *NIX and Windows.
First you must build the vfw2menc program. It is located in the TOOLS subdirectory of the MPlayer source tree. To build on Linux, this can be done using Wine:
winegcc vfw2menc.c -o vfw2menc -lwinmm -lole32
To build on Windows in MinGW or Cygwin use:
gcc vfw2menc.c -o vfw2menc.exe -lwinmm -lole32
To build on MSVC you will need getopt. Getopt can be found in the original vfw2menc archive available at: The MPlayer on win32 project.
Below is an example with the VP6 codec.
vfw2menc -f VP62 -d vp6vfw.dll -s firstpass.mcf
This will open the VP6 codec dialog window. Repeat this step for the second pass and use -s secondpass.mcf.
Windows users can use -xvfwopts codec=vp6vfw.dll:compdata=dialog to have the codec dialog display before encoding starts.
