#336 -V option not working on QNAP TS-209 with Debian

I'm trying to do flac to mp3 conversion on my QNAP TS-209 and cannot for the life of me get VBR to work. The problem is not with flac, since "flac -d file.flac" produces a good wav copy. Then, when trying wav to mp3 conversion, "lame -b 320 file.wav" works out nicely but "lame -V 0 file.wav" does not work. It gives a file that is way too small and that produces no audible output. The lame histogram shows encoding to only 32 kbit/s. I have tried the -x option but it makes no difference.

I installed lame by adding debian-multimedia.org to my apt sources.list.

Investigation of this bug is at http://forum.qnap.com/viewtopic.php?f=147&t=12356&p=57594

If you do not have access to a TS-209 I'll be glad to assist. Contact me at bjohv052@gmail.com.

    What version of LAME do you use?
    Did you compile yourself or do you get pre-compiled binaries?

    3.98.2 for Debian Lenny ARM from debian-multimedia.org (pre-compiled).

    I don't have access to a TS-209. Can you give me some details how LAME gets configured on that machine? Maybe there is some feature detection going wrong with the configure script.

    Hi Björn,

    the link you gave is very useful. It seems to nail the problem down to a GCC bug, which we need to circumvent by taking care of it in our configure stuff.

    I have already contacted the submitter on the forum indicated and I will put a fix on the HEAD branch of our tree.

    I think that I can backport it, but since the original poster is using binaries compiled by Christian Marillat, I guess that he won't be able to benefit from our changes, since Marillat removes the Debian packaging that I make and does it his way. I have been trying to be in contact with Fabien and he has suggested me some improvements to the packaging and I intend to bring it to the state of the art (or, at least, as close as possible to it).

    Regards, Rogério Brito.

    Not really a problem with lame, but with gcc, it appears. Please let me know if there are any further comments.

    Regards, Rogério Brito.

    P.S.: Martin has told me that he could, perhaps, arrange me an ARM box to use for Debian development. Unfortunately, at this time I don't have anything. I can, OTOH, use the patch linked to from the bug...

    This is closed with the patch that Andres Mejia sent me. It would be good to verify if newer versions of GCC (e.g., 4.5 or 4.6) still have this bug.
