So, here i am, stucked with several avi files, and i need to burn these files as DVD videos for my parent's friends. And i've never before done this kind of thing on a linux pc.
After doing some research, here are the steps i took to make this work :
1. Convertion from AVI files to MPEG filesWe need to convert the AVI files to MPEG files, and i use
mplayer for this. Here's my example script of
convert.sh (
NOTE : please aware that the
vcodec parameter is too long for a good view, so i truncate it into several lines. So the lines ending with
4016: actually continues to
keyint=12 without a new line, and line that ends with
cbp: continues to
mv0: without a new line)
mencoder -of mpeg -mpegopts format=dvd:tsaf -ovc lavc -oac lavc -vf harddup -srate 48000 -af lavcresample=48000 -lavcopts vcodec=mpeg2video:vrc_buf_size=1835:vrc_maxrate=9800:vstrict=0:vbitrate=4016:
keyint=12:aspect=16/9:trell:mbd=2:precmp=2:subcmp=2:cmp=2:dia=-10:predia=-10:cbp:
mv0:vqmin=1:lmin=1:dc=10:acodec=ac3:abitrate=192 -ofps 30000/1001 $1.avi -o $1.mpeg
So in my case i would do this command for my
opening.avi file to get an output file of
opening.mpeg
$ ./convert.sh opening
The output of this step is MPEG file[s]
2. Make a DVD filesystemIn this step i use the
dvdauthor software to achieve this. Here's an example script of mine (makedvd.sh) :
dvdauthor -o dvd/ -T
dvdauthor -o dvd/ $1.mpeg
dvdauthor -o dvd/ -T
If you want to split the mpeg file into chapters every 15 minutes, we can modify the script into this (my video is only 2 hours duration, so it ends with 2:00:00):
dvdauthor -o dvd/ -T
dvdauthor -o dvd/ -t -c 0:00:00,0:15:00,0:30:00,0:45:00,1:00:00,1:15:00,1:30:00,1:45:00,2:00:00 $1.mpeg
dvdauthor -o dvd/ -T
Here's an example of command i'd issue for my opening.mpeg :
$ ./makedvd.sh opening
Wait a minute ! What if i have several mpeg files and would like to make them into one DVD filesystem ?
Dont worry ! In this case, you should make an XML file like this :
<dvdauthor>
<vmgm />
<titleset>
<titles>
<pgc>
<vob file="myfile1.mpeg"
chapters="0:00:00,0:15:00,0:30:00,0:45:00,1:00:00"
/>
<vob file="myfile2.mpeg"
chapters="0:00:00,0:15:00,0:30:00,0:45:00,1:00:00"
/>
</pgc>
</titles>
</titleset>
</dvdauthor>
And then to make a DVD filesystem based on this XML file with the command :
$ dvdauthor -o dvd -x input.xml
The output of this step is a directory named
dvd that contains the DVD filesystem
3. Make a DVD ISO imageOkay, now i have the
dvd directory, ready to be made into a burnable DVD ISO image. All i have to do is this :
$ genisoimage -dvd-video -v -o mymovie.iso dvd
The output of this step is a DVD ISO image.
4. Play the DVD ISO imageThis step is optional, but i like making sure of things before burning it onto a DVD-R. In this step, i just need to issue this command :
$ mplayer dvd://1 -dvd-device mymovie.iso
If i want to play specific chapters that i've made during step 2, i'd use this command :
$ mplayer dvd://1 -chapter 2 -dvd-device mymovie.iso
Okay, you've tested the ISO file and everything is like you wanted. Now you can proceed to burn the DVD ISO image. I use
K3b for this. Just fire the application, choose from menu,
Tools -> Burn DVD ISO ImageReferences that help me achieve this :
