Projects / ogmencoder


ogmencoder is a Perl script that uses MPlayer/Mencoder and Transcode to create an OGM (audio Vorbis) backup of your DVD, ready to be burned to a CD-R. OGG (but the usual extension for the video files is OGM) is the file format for multimedia developed by the Foundation. It is very similar to the common Microsoft AVI. The main difference between OGM and AVI is that the new format can store audio with the Ogg Vorbis codec. With this codec, you can decrease the bitrate of your movies (I use 64 kbps), saving space to increase the video bitrate. Ogmencoder is completely automatic. Basically, the only thing you have to do is to insert the DVD in the reader and launch the program.

            % My wishlist:
            > Subtitles.

            Now we got Subtitles, but they are going to be rendered into the video stream with no way of disabling or enabling them, yet. =) Hope that is to come too, sometime.

            Let's look at typical Anime for example:

            Having Japanese and English audio streams and english subtitles - in case I chose Japanese audio + english subtitles. But if I wish to listen to the english audio stream, the subtitles wouldn't be necessary anymore.

            Excellent piece of work...
            For starters, this has made it considerabily easier for me to find out the 'how' of how to use which programs to efficiently make an ogm file.

            The only way I could be more pleased if it were possible to have transcode handle both the video and the audio parts of it all, so one can compare which of the two does better encoding jobs for video, and also to use some of the more specialized de-interlacing (among other) filters that transcode offers for some video sources.

            Please continue to write and extend on this script, keep it as nice and clean (no GUI) as it is while finding additional ways of enhancing the produced output of video and sound.
