File Duration is wrong for some files

[babduljameel]

using (var taglib = File.Create(path))
{
return taglib.Properties.Duration;
}
i tried to use the snippet to calculate mp3 file duration, but it gives me wrong file duration.

Hi I tried with File.Create(path, ReadStyle.Average), but it gives same old wrong duration.
for the attach file the expected duration is 00:21:48 where as the output from the code gives me 00:12:30

Part 17 - Alamaath e Qayamath aur Aalam e Aaqirath - 26.10.2017.mp3.zip

really.
some other programs also gives wrong duration.
badly.

i was looking at the above file. The reason for the wrong duration is the first frame in the mp3 file.
It seems it was encoded using ffmpeg with lavc57.3.
This encoder was inserting an Info frame as the first frame, which has the last byte of the frame header set to 0 and also the 3rd byte contains wrong information.
Therefore taglib is getting a wrong AudioBitrate, which is causing the duration to be calculated wrong.
Taking the values from the next frame produces the correct results.

I guess the solution would be to check if the last byte of the frame header is all 0 and skip then to the next frame.
I'll see if i find some time in the next days.

I'm looking at this right now. I'm not sure what it'll take to fix, but I'll keep everyone posted

[carrzkiss]

Thank you so much for the response.
I am at a dead standstill until that is fixed.
The only thing left to do is to continue designing the website around everything else.

Thank you decriptor.

@carrzkiss Sorry, I've had some stuff come up recently that has prevented me from working on anything at the moment (nothing serious). I'll hopefully have some time in the next week or so

Any updates on this?
maybe it has something to do with this: taglib/taglib#957

[decriptor]

Sorry everyone. My life got flipped upside down a bit. I'm hoping that things will settle a bit in about 3 or 4 weeks.
