Re: Ogg-Vorbis support?
 

Hi

Would you be kind enough to elaborate on that? Is a DSP some sort of an onboard processor for MP3?

Re: Ogg-Vorbis support?
 

Yes. Google for OMAP 1710 (used in N770) or 2420 (N800). There is C55x DSP CPU together with ARM CPU. MP3 decoding runs on DSP.

I also believe that the stock vorbis library makes use of alot of floating point operations which is harder to do for the ARM types. I think I saw an eariler effort to make an ARM version of the library some time ago.

Thanks! You guys sure know a lot. I'm really impressed with the quality of the posts made in this forum. :)

Re: Ogg-Vorbis support?
 

As a business decision i can understand nokia not paying for developing ogg playback in the DSP.

As a proponent of open standards and open source software I find this a sad state of affairs. Ogg is superior to mp3 and patent-free, however the mp3 patent holders keep making vague threats about prosecution against ogg implementations. This scares some companies away. Perhaps nokia too.

This is a crying shame because many games use ogg music. There is a fast ogg decoder (libvorbisidec, also called the 'tremor' library), but it sucks about 10-12% cpu.

To get music playback without the performance penalty i have to convert ogg to mp3 and host the data for the games. What a waste.

I know of one guy who would be interested in implementing ogg playback on the DSP processor, but he's being hampered by lack of access to kernel headers for the dsp. Please support the cause and request dsp accelerated ogg-vorbis playback in the next nokia tablet.

Cheers

subscribe yourslef to the bug report https://bugs.maemo.org/show_bug.cgi?id=1035 the more people do, the more nokia will know how much it is wanted.

(another alternative is to file a new bug about it, then the nokia devs have to mark it as a dupe of the first one)

just noticed that the maemo bugzilla has voting enabled, so you can add a vote to the bug

The tablet software folks do care about Ogg.

Re: Ogg-Vorbis support?
 

I sure wish that OGG was better supported. I have an iAudio X5L that holds close to 30GB of OGGs. That player is ugly but functionally amazing. So I am firmly entrenched in OGG. People need to realize that OGG is better and free. What's not to love?

Re: Ogg-Vorbis support?
 

I am sure they do. I just wish there was a simple solution to the issue. :(
