soundrip fra DVD med transcode

[Klaus Rasmussen]

Jeg vil gerne rippe lydsporet fra en musik-DVD og til dette formål har jeg installeret transcode. Har så forsøgt at rippe med kommandoen:

Kode: Vælg alt

transcode -i /dev/dvd1 -x dvd -T 1,1,1 -a 0 -y mp3 -m track1.mp3

Det giver denne fejlmelding:

Kode: Vælg alt

klaus@klaus-desktop:~$ transcode -i /dev/dvd1 -x dvd -T 1,1,1 -a 0 -y mp3 -m track1.mp3

Der mangler så vidt jeg kan se en shared object fil: export_mp3.so.
Hvordan får jeg den installeret? Den findes ikke med Synaptic.

[Klaus Rasmussen]

Efter at have installeret libdvdcss, prøvede jeg igen; denne gang at rippe til ogg (som er installeret):

Kode: Vælg alt

transcode -i /dev/dvd1 -x dvd -T 1,-1 -a 0 -y ogg -m audiotrack.ogg

Det gav dette noget kortere svar:

Hvordan kommer jeg nu videre........ zob?

[Klaus Rasmussen]

I forventning om, at det måske var nemmere at rippe i ukomprimeret format prøvede jeg:

Kode: Vælg alt

transcode -i /dev/dvd1 -x dvd -T 1,1 -a 0 -y wav -m track.wav

Hvilket gev dette svar:

Det resulterede også i en fil: track.wav på 5 min. Aner ikke hvorfor den cuttede netop her.

Samt en ½Gb wav fil som output indeholdende hele lydsporet.

Men stadig mgl jeg shared object filen til at lave output direkte i mp3.

[Ivan]

http://www.transcoding.org/cgi-bin/transcode?Transcode_FAQ

[Klaus Rasmussen]

Der er ingen oplysninger om den manglende fil: export_mp3.so eller hvorfra jeg får den installeret!

[Ivan]

"2. Installation
I have installed the latest transcode package from RPM (or other pre-built package). Whenever I run transcode it dies, saying it cannot find export_mp2enc.so (or similar). What's going on?

Pre-built packages of some distributions are not complete. This is a general problem. If you want to use the mpeg2enc export module, you will have to compile transcode yourself, or try to find a complete rpm on the net. (ems) "

Så jeg mener da det står ret tydeligt

[Klaus Rasmussen]

Har prøvet at compilere sourcekoden selv. Der kommer en masse fejlmeldinger og ingen export_mp3.so.

[Ivan]

Jeg kan heller ikke se export_mp3.so i "INSTALL" i transcode-1.1.0.tar.bz2

Kan det være at du skal bruge lame i stedet for mp3 i din commando
http://www.transcoding.org/cgi-bin/transcode?Export_Modules

[Klaus Rasmussen]

Godt set, det havde jeg ike tænkt på. Der er en shared object-fil der hedder: export_lame.so

Prøvede med:

Kode: Vælg alt

transcode -i /dev/dvd1 -x dvd -T 1,-1 -a 0 -y lame -m audiotrack.mp3

Starten ser normal ud, men:
