[vlc] Re : Re : ogg help

[jean legrand]

Here is a possible test :

0) Assuming vlc is configured with '--enable-flac',
1) export a sound in Audacity with .flac extension : cbA.flac (created by Audacity)
2) run
vlc cbA.flac --sout file/ogg:cbAtbV.ogg (tranformed by Vlc)

Now, vlc can read cbAtbV.ogg but Audacity can't.

The header of an ogg created by Audacity :
