dvd-slideshow : unknown file type 'raw'

The dvd-slideshow command takes a series of pictures, and transforms it into a mpg stream. You can add subtitles, transitions and music. However, the version in Ubuntu is quite old, and generates quite some problems :

...

[dvd-slideshow] ERROR during ffmpeg execution!

To get the package working, first upgrade to the latest version. The dvd-slideshow homepage offers a .deb version which installs nicely on Hardy.

Secondly, dvd-slideshow repeatedly calls "sox -t raw" in various ways. My understanding is that this line will fail unless libsox-fmt-sndfile is installed.

And last : change the /usr/bin/dvd-slideshow shellscript as follows :


- ffmpeg -i "$tmpdir/audio1.wav" -y -vn -ab $audio_bitrate -acodec ac3 -ar $audio_sample_rate -ac 6 "$tmpdir/audio1.ac3" >> "$outdir/$logfile" 2>&1
+ ffmpeg -i "$tmpdir/audio1.wav" -y -vn -ab ${audio_bitrate}k -acodec ac3 -ar $audio_sample_rate -ac 6 "$tmpdir/audio1.ac3" >> "$outdir/$logfile" 2>&1


Also, change all occurences of audio_bitrate like this

audio_bitrate=224

to

audio_bitrate=224k
