Basics - transcoding flac to mp3 in V 2.0.1

[ady_p_uk]

I recently downloaded Videolan 2.0.1 for Windows to convert some flac files to mp3.

It's been a while since I last used it, so I would have been using version 1.x.x, where I remember having to install a nullsoft codec in the preferences menu and also to select mp3 output. 2.0.1 is totally different and the current wiki guide for transcoding..

http://wiki.videolan.org/Transcode#Tran ... the_Wizard
http://www.videolan.org/doc/streaming-h ... /ch02.html which shows the sequence for an earlier version with <File>, <Wizard> options in the drop down menu - rather than <Media>, <Convert/Save>??

Anyway, here is the process I have been using ..

<Media>
<Convert/Save>
<File>
<Add> (specify source filename.flac via browse function)
<Convert/Save>
<Convert>
<Browse> (specify / create destination file.mp3)

oddly at this point the only extensions available are .ps, .ts, .mpg, .ogg, ,mp4 & .mov

<Profile> MP3 audio selected from drop down
<Start>

VLC then appears to be processing the conversion, with a blue progress bar and a time scroll at the bottom of the player, yet when I check the .mp3 output file it reads 0 bytes. I've tried the same using .mp4 format too

Am I missing some transcoder add-ons which I need to install?

I remember this being the case for the older version I was using in early 2011.

I even tried to run it using the command line function in WIN XP via <Start>, <Run>, <Cmd> and it threw a wobbler at C:\Program Files bit

Confused

Any pointers would be most appreciated.

Hi
I've just tested this with Windows XP and VLC version 2.0.1
With command line....

Code: Select all

"C:\Program Files\VideoLAN\VLC\vlc.exe" filename.flac --sout="#transcode{vcodec=none,acodec=mp3,ab=128,channels=2,samplerate=44100}:std{access=file,mux=raw,dst='C:\filename1.mp3'}" vlc://quit

It gives an mp3 file, size 0KB.

Also tested it with a wav file...

Code: Select all

"C:\Program Files\VideoLAN\VLC\vlc.exe" filename.wav --sout="#transcode{vcodec=none,acodec=mp3,ab=128,channels=2,samplerate=44100}:std{access=file,mux=raw,dst='C:\filename2.mp3'}" vlc://quit

This works OK.

Same results with Ubuntu and VLC version 2.1.0-git Rincewind (revision 1.3.0-git-2068-gb1b423c)

So it looks as though there's a bug when converting flac files.

Probably same as this here ---> viewtopic.php?f=13&t=99204

What are the FLAC samplerates please?

Hi j-b
The flac file that I used in the post above is this:-

Code: Select all

Audio Format : FLAC Format/Info : Free Lossless Audio Codec Duration : 1mn 0s Bit rate mode : Variable Bit rate : 880 Kbps Channel(s) : 2 channels Sampling rate : 44.1 KHz Bit depth : 16 bits Stream size : 6.34 MiB (100%) Writing library : Lavf54.2.100

It's (probably) the same file that I used with the original tests for trac ticket 6400.

Any update on this?

There is a bug created, I think.

[TigerRag]

sorry i don't understand

[luke823]

Is there any update on this?

Transcoding audio to mp3 works for all formats except flac. With flac it just exits immediately with no obvious error in the log. Thanks.

[Jean-Baptiste Kempf]

Yes, the bug is fixed in 2.1.0-git
