Hey,

I'm experiencing a weird issue. I've done some tests with older version and it's happening too, so it may be because a youtube update?

I'm using this command to get the audio extract only for youtube video:

youtube-dl -o '%(title)s.%(ext)s' --restrict-filenames -x --max-quality 140 {link}

For some reason on Youtube, the extract audio will have a duration twice the one on youtube. So for example I download a 3:30 minutes video, the audio will be 7 minutes.

Does someone have the same problem?

Thanks
Tom

For example :
youtube-dl -o '%(title)s.%(ext)s' --restrict-filenames -x --max-quality 140 http://www.youtube.com/watch?v=h5EofwRzit0

Gives a Daft_Punk_-_Get_Lucky_Full_Video.m4a file of 8:15 where the video is only 4:07

With the command you posted, it doesn't extract the audio because it downloads the dash audio version. According to ffprobe:

$ ffprobe 'Daft Punk - Get Lucky (Full Video)-h5EofwRzit0.m4a'
...

If I just run youtube-dl 'http://www.youtube.com/watch?v=h5EofwRzit0' -x, I also get a m4a file with the right duration:

It works fine with ffmpeg, are you using libav? I'm installing it and will test it.

Wow, that's really weird. As you can see, youtube-dl doesn't do any post-processing, so the m4a file is directly downloaded from Youtube. When you play the audio, what's the reported duration? does avprobe {the m4a filename} reports the same duration? What is the md5 checsum of the file (run md5sum {filename}? in my case it's 97cc60491aacac95ab6f75f99ae08e4d (it should be the same for you).

If I play the song the player just goes at the middle of the song automatically. So for this example at 4:07 and starts playing normally.

The strange thing is I've been using this exact command for the past few months without problem.

I've installed avconv 0.8.9 and it reports the wrong duration. Updating to 9.10 will solve the problem (it reports the right duration), so I'm closing the issue. The audio player may be using the old version of avconv, you should report the error to them.
Thanks for the report.
