Hi
I downloaded a music video from YouTube and extracted the audio out with MP4Box. Here is the result: https://www.sugarsync.com/pf/D317495_2839236_755670 foobar2000 plays it well but there is no seekbar slider. However if I play the file with Windows Media Player the seekbar slider works normally so I guess the problem is not in the file itself? This post has been edited by Jarzka: Dec 29 2011, 08:31 |

Raw aac streams don't support sample exact seeking (without parsing the whole file first), so foobar disables seeking. Programs that let you seek in the file are not sample exact. To enable seeking in foobar, put the raw aac file in a mp4 container. You can do this with mp4box as far as I know.

It seems like a Microsoft style answer: "It's not a bug, it's a feature"... I don't know the reason why you can seek in aac files with Media Player Classic, with old "Winamp", with VLC and even with the stupid Windows Media Player and you can't in foobar, unless you put the audio file in an mp4 container. If I want an mp4 container it's ok, but if I want only seek into a dumb aac file, why it's not possible? Forgive my poor english. Regards ggmanci |

foobar2000 mandates sample-exact seeking for the sake of accurate timing and processing. This is not possible in raw AAC files—at least not without consuming a lot of time in order to construct a seek-table like that present in an MP4 container. Thus, foobar2000 disables all seeking within raw AAC.
The other players you mention are presumably not sample-exact, and therefore are not really relevant. Almost all of this was already stated above by The Link. |
