# Naudilus - Nautilus script for audio file conversion
# by Rafael Rigues <<EMAIL: PROTECTED>> - 02/28/2002
# Translations and feedback are welcome!

# Depends on lame (3.91 recommended), gidalog and vorbis tools and libraries (rc 3 or newer)
# Based on code from convert_to_jpeg (David Westlund)
# Based on code from Archiver/Unarchiver (Patrick Largey & David Westlund)
# Thanks to Aurélio Marinho Jargas for miscellaneous help

# Put on ~/.gnome/nautilus-scripts, and chmod +x it!

# Changelog:

# 03/17/2002 * Version 0.5
# * Info: This version was finished on 03/05/2002, and was meant for personal use only.
#  (at least until I had implemented everything I wanted). However, I'm releasing it now
#  to get feedback from other users.
# * I've discovered the cause for oggenc always encoding files at 342 kbps. It seems to
#  be a bug triggered by the combination of glibc-2.2.4-19.3 and vorbis rc 1. Upgrading
#  the vorbis tools and libraries to rc 3 solved the problem.
# * I've also found that not all versions of lame have the --decode option. I don't know
#  when it was added to lame (and I'm too lazy to check the changelog now), but I'm
#  using lame 3.91.
# * Now I'm using pipes to decode/encode the file simultaneously (thanks to FRS for being
#  so persistent about this), so there's no need to create (and delete, afterwards) a
#  temporary WAV file. It's also one less thing to check if it will be overwritten or not.
# * More code cleanups. "...Smarter! Stronger! More Aggressive! I feellike I could..." :)
# * Now also converts WAVE files to MP3 or Vorbis!

# 03/03/2002 * Version 0.4

# * Spent a whole day trying to reorganize the code, tighten it up and make it look
#  smarter and prettier. Did I succeed? :)
# * Now Naudilus detects if the file exists (both the temporary .wav file created during
#  the conversion and the resulting .mp3 or .ogg file) and asks the user if he wants the
#  the file to be overwritten. If not, the file is ignored, and Naudilus will proceed
#  with the next file.
# * I've found a strange bug where oggenc is now ALWAYS encoding the files at an average
#  342 Kbps, regardless of the arguments I pass to it. I suspect it is a fault on the ogg
#  encoder, caused by a full-scale system update (which included a new version of glibc) I
#  did today. I will find out more about this tomorrow, when I test the script on my
#  machine at work.

# 03/02/2002 * Version 0.3

# * Naudilus now asks which format to convert the files to. Note that if you choose
#  to convert a file to it's current format (eg. convert an MP3 file to MP3), it
#  will be simply ignored, and Naudilus will proceed with the next file.
# * Possible conversions are: MP3 -> WAV, Ogg -> WAV, MP3 -> Ogg and Ogg -> MP3.

# 03/01/2002 * Version 0.2

# * Changed the name to "Naudilus". Thanks to Fabio Ricardo Schmidlin for the name!
# * Detects the filetype before attempting to convert the file.
# * Uses the file extension to determine which kind of file it is, if the filetype
#  detection fails.
# * Added Vorbis to MP3 conversion.

# 02/28/2002 * First version. It seems to work! :)

# And now, the incredible, ever expanding TO-DO list!!

# * Check for write permission before trying to create a file. If such permission does not exist, ask
#  the user where to write the file.
# * Recurse directories and subdirectories (Dangerous??)
# * Generate MP3/Ogg files with complete tags (artist, album, genre, etc...). Grab the tags from the
#  original MP3/Ogg file

# Talk is cheap! Now show me the code!!!

Salve e feche o gedit. Depois entre com o comando:

Código Selecionar Expandir

chmod +x ~/.gnome2/nautilus-scripts/Converter\ arquivo\ de\ audio

Pronto. Agora basta clicar com o botão direito do mouse em cima de um arquivo de áudio e ir em Scripts > Converter arquivo de audio.

Não seria isto
http://ubuntuforum-pt.org/index.php?topic=442
a funcionalidade é a mesma...

[LedStyle]

Olha... agora que vi a foto parece que é a mesma coisa... rs. Mas eu peguei o script la no site do G-scripts. Tava procurando uns scripts legais pro nautilus e encontrei isso ai.

De qualquer forma funciona que eu ja testei hehehe.

Fiz igual vc falou e qnd cliquei no arquivo>converter não apareceu nada...

...cliquei no arquivo > converter não apareceu nada.

Eu busco a praticidade da vida, complicar pra que? Para converter para Ogg Vorbis, MP3, FLAC ou WAV, eu uso e recomendo o SoundConverter. O único defeito que acho é q a maior qualidade é só 256 kb/s.

Fiz igual vc falou e qnd cliquei no arquivo>converter não apareceu nada...

tem que mudar o DONO e  o  GRUPO do arquivo para "root"

ai aparece.

e o script é legal demais, usava muito isto no KUBUNTU, pois o KONQUEROR, tem muito mais opcões que facilitam a vida usando o "gerenciador de aquivos" acho que quanto mais opções tiver melhor para manipular os arquivos.
converter, abrir com.., editar, mandar pra p*** q** p****.
