Re: [mad-dev] Xing ID3 and VBR

I'm a little concerned about do_straight_multiplication(); If the file has extra headers randomly placed about it, you can be off by a small amount (or perhaps large amount).

In my experience this isn't really an issue.

For my application, I'd tempted to try finding the time in the following order:

1. check file's extended attribute (OS/2ism here)
2. check for xing header
3. check for TLEN in ID3 v2 tag.
4. count frames
5. assume CBR and just multiply
6. give up

Don't underestimate the amount of time it takes to count the frames. This added around 5 seconds to the start of each song when I did it. Some minimal inaccuracy with frame numbers would probably be acceptable if it increased speed that much.
