Title: Bug in Analyze Audio
Post by: JoeCotellese on May 02, 2006, 08:28:22 pm
Hello,

I seem to have a bug in the Analyze Audio function. Every so often analyzing a group of files would hang the Media Center. I've identified a file which exhibits this problem. Who should I send it to?

Play the file to see if is corrupt.

Check the file for illegal characters, or if it is a very long file name, shorten it if you can.

Sometimes editing the file name will fix it.

Try analyzing just the problematic file.

File is Polythene Pam, the file plays fine, the filename is pretty short. Not really sure what is going on.

Make sure you have the latest MC 11.1. (from the top of this board)

A similar issue was fixed several builds back.

I definately have the latest build.

Here is some more information. I tried again to run the song through Analyze audio and it worked fine.

This problem seems to happen only when I analye a group of M4A files encoded via iTunes. It's never the same song twice. I also have never noticed it when I encode a group of MP3 files.

I have the same problem. The error is different depending on which directshow filter I'm using:
1) with coreaac: MC hangs. The contents of the analysis window is completely white. The contents of the main MC window no longer update
2) with ffdshow: analysis stops but MC is still responding. However, while playback still works for new songs, any further audio analysis is impossible. I get the error 'audio analysis needs files on a locally accessible drive' or something along those lines. Everything else seems to keep working, after restarting mc (killing it is not necessary) analysis works again.

It is indeed always on a random file that the error happens, no matter which directshow filter is used.

I have tried this with haali media splitter as well as mp4splitter. (though I'm not sure how to tell windows to use a specific splitter when both are installed)

Good, I thought I was going nuts.

I seem to have problem number 1. I've never looked to see what filter is in use. I'll check and post it here.
