It should also merge the standard subtitles. The only problem is that the .avi is still large.

user@server:$ mencoder "video.mkv" -ovc lavc -lavcopts vcodec=mpeg4:threads=8:vbitrate=3000 -oac copy -o video.avi

And maybe mkisofs to create a dvd iso. Or growisofs to burn directly. (If you need to identify your video, install Mplayer.

user@server:$ yum install ffmpeg spumux dvdauthor mkisofs growisofs mplayer

First we need a .mpg or .mpeg file. For example if you have an .avi file, convert this to .mpg (change pal-dvd to ntsc-dvd if needed)

user@server:$ ffmpeg -i movie.avi -target pal-dvd movie.mpg

Now we have the .mpg file we can set up the XML files with the settings for the conversion. Create spumux.xml and add the following settings into it.

<subpictures>
   <stream>
      <textsub filename="yoursubsname.srt" characterset="ISO8859-1"
        fontsize="28.0" font="arial.ttf" horizontal-alignment="left"
        vertical-alignment="bottom" left-margin="60" right-margin="60"
        top-margin="20" bottom-margin="30" subtitle-fps="25"
        movie-fps="25" movie-width="720" movie-height="576"
     />
   </stream>
</subpictures>

You have to replace the filename, movie-width and the movie-height to your video preferences. You have seen them while converting if not use this command.

user@server:$ mplayer -identify output.mpg

Now before we start processing, we need arial.ttf in our .spumux folder. If you don’t have a .spumux folder, create one;

user@server:$ mkdir ~/.spumux

OK — now we are all set, what you have to do now is use the following command.

user@server:$ spumux spumux.xml < out.mpg > output.mpg

Alright, when this is done we have to make another .xml file. Create dvd.xml and put this in there.

<dvdauthor dest="DVD">
  <vmgm />
   <titleset>
     <titles>
       <pgc>
         <vob file="output.mpg"/>
       </pgc>
     </titles>
   </titleset>
</dvdauthor>

Obviously you have to change the vob file to your output video name. When you have done that we can do the following command.

user@server:$ dvdauthor -x dvd.xml

You have just created a dvd including subtitles which you can enable or disable. What you got to do now is simply make a ISO or burn it directly to your blank dvd.

To make a ISO you can use this command:

user@server:$ mkisofs -dvd-video -o name-your-dvd.iso DVD/

If you want to burn it directly without making a .iso then use this command; (Replace /dev/scd0 with the device path to your DVD recorder)

user@server:$ growisofs -Z /dev/scd0 -dvd-video DVD/

Starts at 5.00 and ends on 8.00.

Well here you find out how to do using Bash ~ Linux!

1. First, make sure you have installed the package “Lame” (Should be easy to find @ google.com for any Linux OS)
lame installed

2. Download THIS bash script and move it to the folder where the .flac files are stored.

3. Give “flac2mp3.sh” 755 rights. (chmod 755 flac2mp3.sh)

4. OK — we are in the folder where the .flac files are stored.. We have copied or moved the bash script we need to the same folder.. So now we can start converting. (See picture)
flac

5. Start the script to convert your .flac files to .mp3  (./flac2mp3.sh)
flac-converting

6. You can see the .flac files getting converted to .mp3 — All .flac files will be converted in that folder.
flac-converting2

7. When converting is done, you’ll see that the .flac files are still there. I recommend you to check if the .mp3 files work and then remove all the .flac files. (rm -f *.flac)
removeflac

8. Done. All your .flac files are just converted to .mp3
 done-converting

Have fun & Please leave your thoughts in a comment!
