Make a DVD out of just about any video file.

I recently decided to try to transcode an .mp4 (quicktime) movie to burn on to a dvd. Using a windows version of MPlayer and following these instructions I started the transcoding process.

mencoder -oac lavc -ovc lavc -of mpeg -mpegopts format=dvd:tsaf 
-vf scale=720:432,expand=720:576,harddup -srate 48000 -af 
lavcresample=48000 -lavcopts vcodec=mpeg2video:vrc_buf_size=1835:
vrc_maxrate=9800:vbitrate=5000:keyint=15:vstrict=0:acodec=ac3:
abitrate=192:aspect=16/9 -ofps 25 -o movie.mpg movie.mp4

This was not the end of the story however. The next step was to convert the output MPG file info a DVD filesystem. This was done using DVDAuthour fortunately version 0.6.9 comes in precompiled windows binaries. The documentation for DVDAuthour was a little flakey however the easiest way was to create the XML file

<dvdauthor>
     <vmgm />
     <titleset>
         <titles>
             <video format="pal" aspect="16:9" resolution="720x576"/>
             <pgc>
                 <vob file="movie.mpg" />
             </pgc>
         </titles>
     </titleset>
 </dvdauthor>

And then build the dvd filesystem using

dvdauthor -o ./dvd -x dvdauthour.xml

Finally I have to burn the files to disk using the windows version of growisofs (which requires mkisofs) Using the command

growisofs -dvd-compat -Z e: -dvd-video -V "VIDEO_DVD" ./dvd
