Summary0002290: No audio in Vorbis rendering
DescriptionTried to reopen 0002265, but didn't find the option. This keeps happening in my system:

- Fedora 14.
- kdenlive SVN r5837.
- FFmpeg 0.6.3-rpmfusion

Including the "aq" parameter (which only appears in the factory profiles for Theora >= 1000K) doesn't solve the issue.

I am unable to reproduce.
What does the render profile look like?
What do you mean by it only works for bitrate >= 1000K?

Btw. I use ffmpeg 0.7.1

Doesn't work on any profile. I mean that "aq" appears only on Theora profiles of 1000K and above.

For instance, Theora 800K looks like this:

acodec=vorbis ab=128k ar=44100 vcodec=libtheora minrate=0 b=800k aspect=%dar

And Theora 1000K is:

acodec=vorbis ab=128k aq=30 ar=44100 vcodec=libtheora minrate=0 b=1000k aspect=%dar

But I don't get audio in any of them.

As developer of xjadeo I know well what one feels when ffmpeg pulls the rug from under your feet :-) Maybe I should ask this to them, but I thought maybe someone here would have already figured this one out. I'll keep researching.

Mmm, ok, apparently this particular version of ffmpeg doesn't include a "vorbis" codec, perhaps a packaging decision? Changing "vorbis" to "libvorbis" does the trick. Apparently libvorbis produces better quality sound, so I guess it is all good.

As far as kdenlive is concerned, changing the theora profiles to libvorbis introduces a new dependency (libvorbis). Maybe it would be a better idea to split "Theora" in "Theora(vorbis)" and "Theora(libvorbis)" group, and show one of them or both depending on their availability?
