WMA again

[Llorean]

Yeah, and when Preglow offers to help optimize, you should accept. ;-)

Great work Marsdaddy!

[Marsdaddy]

When I had a look at the patch, I noticed you only seem to use 32 bit multiplies everywhere. Might the precision problems be related to this? We usually use 64 bit muls pretty much everywhere we can.

It's not that kind of inaccuracy, which makes me think it's a simple bug -- I encoded a simple sine wave to wma which I then decoded to wav and compared to the original sine wave - it's smooth enough but every so often the sample becomes inverted. I will however probably switch to using 64 bit before submitting.

I appreciate the comment about optimisation and once I shake out these basic decoding bugs I will submit -- functionality before performance! 

Thank you all for your kind comments and interest - it's appreciated. Nice to be a small part of something good.

It sound to me like the sample value could be overflowing. I believe Musepack originally had a similar bug, which preglow fixed.

if this is integrated by the time 3.1 is released, it will make the first official build on iPod even better

I have 1000's of WMAs trapped inside my iRiver H320 / Rockbox, just deparate to be released

Waiting in eager anticipation...

Thanks for your effort, Marsdaddy

I only have a few .wma's, but I think this is such a good feature for rockbox and for rockbox/open-source advocacy that I'll be making / downloading some more files just so that I can help test this. 

Keep up the good work!

Just another vote for wma,

My brother just gave me a bunch of wma files.  He doesn't have the original source, so this codec for rockbox would be a life saver.

Cheers big ears.

I had a dream about this the other day

I've only got a few WMAs that I downloaded from the website of one particular artist. The other tracks by this guy I got from CDs. I can listen to half of his stuff in Rockbox or the other half in the original firmware. Too lazy to re-encode

Thanks for the work you're putting in, Marsdaddy. And everyone else for that matter.

I can't wait until this is finished. My friend just gave me a couple hundred wma's, and neither rockbox nor the apple firmware can play them. Since it looks like it's gonna be a long time since this is released, i guess my only choice is to convert them to ogg. Keep up the great work .

Yeah, real-time WMA decoding would make Rockbox even more totally ass-kicking than it already is. Seriously Inno and iRiver should just ressurect the H1xx series with a better screen and a teeny circuit breaker (for protection against incorrect power input) and just sell it with Rockbox pre-installed. WMA support would absolutely rule! Thank you, good luck and may the god of your choosing speed your progress.

Well, let's first see if Marsdaddy turns up here again. It's been over a month since his last post.

Sounds like your doing some great work marsdaddy - but if you've hit a brick wall or won't have the time to continue things for a while, i think there are a number of people anxiously anticipating this codec (including me) and also a number of people willing to lend a hand if you want. That aside i fully understand wanting to achieve it yourself, i'm exactly the same! keep up the good work.

This is a most exciting project you've undertaken, Marsdaddy.  Please continue you work - this should be a huge deal when you get it working - remember when HP didn't add (enable, actually; since the PortalPlayer chip supports it natively) WMA support to the iPod despite the rumors?  Just the rumors made a pretty big splash.  I've been waiting for this ever since HP dropped that ball.

I would finally buy an iPod if/when this works.

[Llorean]

It wouldn't allow you to play DRM-protected WMAs anyway.
And there are better formats for you to convert your CDs to, so WMA shouldn't really be a show-stopper from buying an MP3 player supported by Rockbox.

Also, where did you get that the PortalPlayer chip natively supports WMA? Are you using "supports" in the sense that it's a multipurpose processor and can decode anything someone writes a codec for?
