no VBR Header in extracted audio

[menachemshapiro]

youtube-dl --version --> 2012.10.09
FFmpeg version 0.6.6-4:0.6.6-0ubuntu0.11.04.1
FFprobe version 0.6.6-4:0.6.6-0ubuntu0.11.04.1
python --version --> Python 2.7.1+
OS: Ubuntu 11.04

I run the command:
youtube-dl -tci --extract-audio --audio-format mp3 OyeafzF4WOk

analyzing the mp3 file that is produced using mp3val give the following error message:
VBR detected, but no VBR header is present. Seeking may not work properly.

Hm...I'd say it's more of an issue with ffmpeg, as it's the one making the actual conversion. Here's what I get when I run the same series of command:

>  mp3val Mashpia\ \&\ Mekabel\ -\ Episode\ 1\ -\ Our\ True\ Nature-OyeafzF4WOk.mp3
Analyzing file "Mashpia & Mekabel - Episode 1 - Our True Nature-OyeafzF4WOk.mp3"...
INFO: "/home/tails/Bureau/Mashpia & Mekabel - Episode 1 - Our True Nature-OyeafzF4WOk.mp3": 12300 MPEG frames (MPEG 1 Layer III), +ID3v2, Xing header
Done!

I'm not getting any error message in that instance, and the MP3 file is encoded with a variable bitrate. I'm using ffmpeg 0.10.5, which may explain it: maybe older versions of ffmpeg don't write any header while newer versions do. It's just a supposition though, but that seems plausible.

Closing as a Ffmpeg issue. Please try to convert manually a video to mp3 to confirm
ffmpeg -i video.flv -aq 4 audio.mp3

I tested the ffmpeg command and got the same problem, so definitely an ffmpeg issue.

Thanks,
