Full Version: Incorrect Bitrate with ABR and --resample

I'm experiencing a problem with LAME 3.98b4. When ABR mode is selected and --resample is set to 24 kHz or lower the file is encoded using the maximum bitrate for MPEG-2 (160 kbps) or MPEG-2.5 (64 kbps). When --resample is not used the problem doesn't happend. I'm using the rarewares compile.

Does anybody else have this problem?

Thanks for reporting, we'll try to fix that for the next release.

There is now a bug fix in CVS.
